How to open any intercom without a key using Metacom. A guide for those who have poor memory: how to open an intercom without a key. Open Eltis system without a key

Each intercom manufacturer has a so-called developer code: knowing them is useful in case you forgot the magnetic key when leaving the house in the morning or lost it.

These codes work if the device’s factory settings were not changed when installing the device. As a rule, most installers do not bother changing standard parameters, although there are exceptions.

Opening the entrance door using the developer's code is not illegal!

You can safely use the combinations below if they suit your device. Do you think they could be used by attackers? Alas, they are the ones who have known these codes for a long time, so any such combinations are an open secret. Just try whether they are suitable for your intercom or not. And then you’ll see they’ll come in handy.

How to open the “Visit” intercom

One of the most complex options, since there are several basic codes for these devices.

You can try dialing *#423, 12#345, 67#890 or *#4230. If none of these combinations work, then you can try to open the intercom using the developer menu.

You can enter it after entering #999. When you hear two intermittent beeps, dial code 1234.

If this does not help, try the sequences 0000, 9999, 3535, 12345, 6767. If this does not give the desired result, then press 2, wait a couple of seconds, then #, then 3535.

The need for safety comes first for many, and this is at the level of instincts. Therefore such electronic devices how intercoms are so popular. After all, competent protection is necessary for any home, as well as to preserve the peace of mind of the homeowners themselves. The modern market offers a huge range of products, and you can choose suitable option, only by studying the characteristics of individual models and interesting offers from manufacturers. But there are often situations when our inattention or poor memory forces us to leave the house without a precious key. In this case, knowledge of how to open an intercom without a key will come in handy. We will consider this issue in today's review.

What is an intercom: purpose and areas of use

An intercom is a security device that has a wide range of applications. It allows you to save entrances from the antics of drunken youth, and apartments from visiting robbers. In an organization, such a device is necessary to protect against unwanted visitors. Video intercoms can also be used as a simple, but effective system video surveillance. Technology with a video function is useful when you need to leave children at home alone.

There are also some statistics. The intercom helps protect the entrance from drug addicts and homeless people by 98%. According to utility workers, costs for repairing the entrance, painting walls, repairing elevators and replacing railings are reduced by 90%. District police officers note that thanks to intercoms, the number of complaints about theft from apartment owners has decreased.

The principle of operation of the intercom: device features and encoding

Let's look at the design features of the intercom. Its constituent elements are two blocks. One is a calling panel, and the other is a subscriber device in the form of a telephone handset. An additional element is a lock with a magnet or mechanical type. You can open the device remotely from your apartment or using a special key.

The product diagram for individual needs involves the use of a relay with an electromagnetic field for switching power and communication circuits.

Let's consider the main stages of the intercom:

press the call button on the device panel;
the contacts close and the signal passes to the subscriber device. At the same time, the homeowner hears a call signal;
Depending on the device model, you need to pick up the handset or press the intercom button. An electromagnetic relay switches the elements of the microphone and loudspeaker;
After communication, the owner can approach the door or open the door with a simple key press.

Multi-apartment intercoms operate on the principle of a mini PBX. They come in two types:

Analog- the most common option. They create communication, control over the lock and a system for passing residents using the same type of key. Each apartment is connected to the device with two wires. A multi-core harness stretches along the entrance, connecting the wires of the calling panel to the subscriber device. An important component of the system is the switch, through which communication is carried out.
Digital intercom differs little from the first option, but the encoding of numbers in it is performed in the binary system. A two-wire wire is used for communication, making installation of the entire system easier.

All residents must remember secret codes or a password to unlock the intercom. This knowledge will be needed if the key is lost. The device cannot be unlocked or recoded by a person who is not a service technician.

Basic ways to open an intercom without a key

But what if the key is lost and you need to do something urgently? Not everyone knows how to open a door with an intercom without a key, but there are some interesting techniques:

use of force. At the bottom of the door, under the handle, you need to rest your foot and sharply pull the handle. The stop is especially important here, so you need to pull the door with pressure from your foot;
universal key. There is a special key that is suitable for any device. But the keys can vary greatly;
use of code. It is important to know certain combinations of numbers to hack a program;
expectation. If the intercom is in an apartment building, then you can wait until the neighbors arrive;
go to the menu. This will require knowledge of codes;
cooling. IN winter time you can put a snowball on the keyboard and after 15 minutes an error message will appear and the lock will open;
use of a stun gun. The device must be applied to the reading device and given a shock.

Is it possible to make a universal key for an intercom with your own hands?

Keys for security systems come in various designs. This can be a contact-type carrier - a tablet, as well as contactless magnetic keys, key fobs or cards. In rare cases, two-pin keys are found. Each key has a specific code, which is recorded at the manufacturing stage. But the code can be changed. This can be done if the final stage of the firmware is not completed or the workpiece can be changed.

Making a universal key for an intercom on your own may not be so easy, because there are no completely universal solutions. There is also a tablet suitable for various locks, but much is determined by the manufacturer himself.

In conclusion

Now, how to open an intercom without a key is not a secret for you. And this is especially easy to do if you know the codes. Print out this review and place it in the inside pocket of your bag. It may well happen that someday you may need them, and you will thank the author with a like or repost. But it is worth remembering that many methods, if used incorrectly, can cause great harm. If you have any questions, you are welcome to discuss.

The process of developing and entering special numbers for intercoms into the lock is carried out at the stage of manufacturing the device, so most often they are the same for all models of the same company. But they may change depending on the wishes of the representative company.

But often, devices that have not been reprogrammed end up on the sales market, which means that almost every modern person can easily enter an entrance with an installed lock if they know the required combination of numbers.

Legislative justification

In accordance with the provisions of the current legislation, anyone who has forgotten the keys to the entrance, lost them, or, if necessary, to urgently get into the house, can open the doors of the entrance, garage or office by dialing the necessary numbers in a certain sequence. It is also allowed to use the code if, for example, a person was invited to visit, but a friend (girlfriend) does not answer the call on the intercom.

However, hacking doors and electronic locks in this way, for fraudulent purposes, for profit, robbery and robbery is strictly prohibited by law. Otherwise, criminal penalties follow.

Factorial

The intercom of this company is characterized as one of the most reliable, which is almost impossible to open! This is a myth! The manufacturer regulates its products as equipment that requires a mandatory change of factory settings, but you can still try to hack Factorial!

In order for the SIM to open, you need to enter the six-digit code 000000 and 123456 on the keyboard panel.

If in this case the door does not open, there is additional opportunity, sequential key combination:

"180180".
"call button"
"call".

Metacom

A fairly simple intercom, with a system circuit using Factorial technology.

Such a device can be opened in three different ways:

It is necessary to enter sequentially the following combination of numbers and keys located on the control panel:
- "Call button."
- “Number of the 1st apartment of the entrance.”
- "Call button."
- "The display shows the word COD."
- "5702".
If the first method does not give the expected results, you should use the second method:
- "65535"
- "call"
- "1234"
- "call"
The third method is much simpler, but requires entering prime numbers accurately and consistently:
- "1234"
- "Call"
- "Challenge Again"
- "4568"

Metakom locks have a model MK - 20 M/T, the opening of which is significantly different from other standard types and involves two opening methods:

First method:
- "Call".
- "27".
- "Call".
- "5702".
Second method:
- "Call".
- "Call".
- "4526".

Visit

Today, the equipment of the Visit company is as reliable and safe as possible from burglars and intruders, in comparison with analogue options. This is due to the presence of a large database of system codes and keys, which are not so easy to pick up in the future. The company's employees pay special attention experiments with system programming of your intercoms.

However, if the supplier company has not changed the factory settings of the system, you can try to hack them by entering the following combinations to choose from:

*#423.
12#345.
67#890.
*#4230.

In addition to this method, you can use the device service menu, to activate which you need to press the #999 keys, after which two short beeps will sound and you can enter the standard code 1234 or 0000; 9999; 3535; 12345; 6767.

If after this one signal sounds, the door has yielded to opening; if two signals, unfortunately, all attempts were in vain.

To adjust the menu options of the Visit intercom company, you should know several basic rules and techniques that can greatly facilitate the process of using the system in a wide variety of life situations:

Buttons: “2” – pause:
- “#” is the second pause.
- “3535” - opening the door.
Buttons: “3” – copy of the key to the intercom: “#” – entering the attached key into the system database.
- “4” - delete all saved keys from the memory database.
- “#” - confirms all changes and settings.
- “*” - exits the menu option.

Digital

In order to enter an entrance or house on which a Digital lock is installed, you can use two proposed methods:

The following steps must be followed sequentially:
- Enter “07054” or press “call”.
- Press “41” or “call”, “1410”.
The second case will be relevant if the house has apartments numbered 100, 200, 300, 400, then:
- Press "call".
- Enter apartment number 100 or 200.
- Press "call".
- Enter the combination “2323” or “7272” or “7273”.

Eltis

Such electronic systems are the simplest, both to use and to open without a special key. This is due to the fact that almost all codes and electronic keys are standard and of the same type.

To open such a door without a special key, you will need only two simple combinations that will surely work:

"Call" + "2323".
“Call” + “7273”.

Keyman

The intercom from this company is the most reliable, which almost no burglar can crack, especially an inexperienced person encountering such a problem for the first time.

To open such an electronic lock, there are only two combinations, when used, not all doors open:

Press the “K” button:
- Combination "100".
- “789” (followed by a beep).
- "123456".
Press the "K" key:
- “170862” (followed by a beep)

Universal key

Today, doors with electronic locks are so common that they are installed in almost every home and in every entrance. The technology on which they are based is called Touch memory, which is opened with a special key-tablet.

And if there are a lot of such doors, it means that each person will have to carry several of these keys on his key ring: for home, office, garage, etc. This is quite inconvenient and impractical, which is why a universal electronic key for the intercom was created that opens everything doors from various manufacturers.

1. Where to buy

Today, such universal electronic keys are widespread, so purchasing them is not difficult. For example, it is very easy to buy such a key on the Internet, in special stores, in repair departments and in the provision of services for the production of individual keys.

2. How much does it cost?

Special universal keys for intercoms have different prices, depending on the manufacturer and configuration; on average, today the price ranges from 300 rubles to 600 rubles.

Universal keys open up to 90% of electronic magnetic and mechanical locks, as well as many doors made in China.

3. How it works

These keys have a specially designed chip inside that contains 64-bit code developed by specialist manufacturers. The code consists of a 48-bit unique serial number, an 8-bit code and an 8-bit checksum code.

Upon contact with the door electronic panel, the developed code is transmitted over a single-wire bus in serial form. So, the code is read by a receiving device, a memory device, which emits a sound signal when the doors are opened.

Pros and cons

Such keys are becoming necessary and relevant for workers in the following specialties:

Postmen.
Policemen.
Couriers.
Housing and communal services employees.
Doctors.
Repairers (plumbers, mechanics).

Before trying to use one of the above combinations, it is recommended to try calling one of the apartments and politely and tactfully explain the current situation in “human language”. In many situations there are good-natured people who understand the complexity of what is happening and open doors.
There are several methods for unlocking an electronic door using a stun gun; to do this, you need to attach the working device to the reader panel and apply a shock.
You can use force to break such locks (for men), to do this you need to hit 10 cm below the reading panel, in the place where the electronics are directly located.
All of the above options for pressing buttons and entering numbers to open electronic locks are only relevant if the customizer has not changed the factory code combinations.
The combinations are quite varied, depending on the purchased model and series of a particular lock.
If you need to pick a lock in the winter, everything is done much easier. You need to take a lump of snow and place it on the keyboard panel. The lock can be opened after an error message appears on the screen. This is due to the fact that with a strong temperature drop, the lock malfunctions due to hypothermia.
For locks with a magnetic system (important! without mechanics), you can open it using your own strength. It is necessary to place your foot on the side where the door directly opens and pull the handle firmly - the door will definitely open.

Today, installation and maintenance companies pay great attention to issues of not only the convenience of device users, but also the overall reliability and vandal resistance of the access control solution.

It is in matters of unpretentiousness and reliability, as well as minimal possibilities of unauthorized access, that one of the leaders is the KS intercom.

These devices have a fairly impressive list of advantages, both from the installer companies and from ordinary residents of the entrance.

Features of KS intercoms

KS intercom can confidently take a leading position in terms of technology.

In design:

modern polymer glass to protect the miniature display;
completely contactless, maintenance-free keyboard, contact is detected by infrared sensors, finger position is tracked by software;
the front panel is a solid piece made of durable metal;
The display is clear, bright, and positioned so that information can be viewed through the protective glass without distortion from any angle.

KS entrance intercom 2006 devices can work with two types of keys, both the usual Touch Memory tablets and contactless ones (Proxy modification).

Also, all models have a convenient feature for installation companies: the equipment is compatible with a huge range of magnetic locks and can work with tubes from different manufacturers.

The entrance KS intercom works reliably at temperatures from -40 to +55 degrees, is easy to install, is protected from moisture, and guarantees reliable operation of the finger position detector in the presence of a wide variety of interference in the coverage area of infrared sensors.

Opening these devices, as well as opening intercoms, is quite difficult. However, under certain conditions, it is quite possible to get into the entrance, change personal codes, and carry out some types of programming.

How to open a KS intercom without using keys

Like all devices for controlling entrance access, there is a standard KS digital intercom code.

The instructions for installers require changing this set of numbers. Even the documentation for specific device models takes into account that the master sets his own personal number for access to programming and service functions.

However, the KS factory intercom code for some models is quite complicated, so installers often do not bother changing the standard sequence. Therefore, you can get into the entrance using one of the digital combinations.

There is also the simplest, but time-consuming way to open a door with KS intercoms. It works on all models with a contactless keyboard, including Akrades modifications and others.

To unlock a magnetic lock, you will need:

block more than two openings for the passage of IR rays;
wait 10 to 12 minutes;
After Err appears on the display, wait another 45 seconds. It is at this interval that the intercom will begin to turn the lock’s power on and off for 10-15 minutes.

The holes behind which the IR LEDs and tracking sensors are located are located at the end of the recess in which the device’s keyboard is located.

They have a very small diameter. The instructions for the KS system clearly indicate that the transition to emergency mode occurs only when 2 or more sensors are blocked.

You can close the holes using your palms (there are 3-4 of them at each end of the recess), if you have the patience to stand for 10-12 minutes. Or - seal them with thick electrical tape. This method is guaranteed to work on all CS models with a contactless keyboard.

Settings mode

All detailed instructions for programming are given in the documentation for the specific model. Most full set commands has the latest model KS intercom 2006.

Entering the service mode is done by dialing the combination K-240361-call-0000-call. Here 0000 is the individual code of the installation wizard; you can enter the settings change mode only if the service company has not changed this set of numbers.

If you successfully enter the programming mode, the display will display a sentence like Here you can immediately unlock the lock by pressing 0 (leaves the intercom in programming mode) or 8 (unlocks the doors and exits the mode).

Mode 5 turns on or off the ability to open the door from the handset or use the apartment access code. To change the parameter:

press 5;
dial the apartment number;
press K;
enter 1 to enable opening by handset and code or 0 to block the option.

This section of the settings will be extremely useful if for some reason the service company has disabled the intercom for the subscriber. If the installers have not set individual access codes for the apartment, this can be done from the programming menu. To do this, press K-subscriber number-K-four-digit code-K.

An unpleasant feature of the KS series intercoms is the inability to enter new keys for an apartment into the device’s memory without a special master key, which only the service company has.

Therefore, if one of the contact tablets issued at the conclusion of the contract is lost, the easiest way would be to order a universal key, the production of which is offered by many workshops.

Codes

For CS intercoms, there are quite a few known combinations for opening the door. Depending on the modification, the following may be suitable:

K-0000-98-K or K-000000-98-K;
K-377-698-K;
K-0903-98-K;
K-240361-call-0000-call-8.

All changes to the main service codes, assignment of a master key and other operations for adjusting the zero security level cannot be carried out without opening the device and closing the contacts on the electronic board.

It is also impossible to reset the settings by applying voltage via the service bus (which will also require physical access to the intercom).

Universal key

As mentioned above, CS access systems offer high compatibility with equipment from various manufacturers. This applies not only to locks, but also to contact keys.

KS intercoms work with tablets from all four well-known manufacturers. Therefore, making a universal key for the entrance is not difficult. This service is offered by many companies and private workshops.

It works according to two main methods. The first uses factory codes, which are necessarily written by the manufacturer of the access control system into the device’s memory.

They are stable and depend on the model of the intercom system. Another technique is the use of area codes, if entrances are equipped centrally and companies prescribe digital sequences transmitted to firefighters, police, and doctors.

Such keys operate within a certain sector of the city, but are guaranteed to open doors.

Conclusion

A correctly installed KS intercom with reprogramming of its individual code is almost impossible to open and reprogram without obtaining universal access.

However, the ability declared by the manufacturer to block the sensors and put the device into emergency mode gives a chance to get into the entrance quite easily. But, in order not to create difficulties, it is rational to order spare universal keys.

Video: How to open a KS intercom without a key

Nowadays it is almost impossible to find high-rise buildings whose entrances are not closed with steel doors. The only difficulty in using an intercom is the loss or demagnetization of the key. IN similar situation, if the neighbors do not answer the call (they are absent, they do not hear), and there is no one at home, a lot of problems arise.

Companies involved in the installation of protective systems of this type are silent about many things. To the question of apartment residents who do not want to donate money for “modernization” front door on how to open an intercom without a key, the answer is standard - purchase in the required quantity. Is this true and what to do in case of force majeure?

There is no full guarantee that these tips will help you open any intercom without a key, but certain techniques sometimes turn out to be effective: tested. Much depends on the features of the locking device design, the thickness of the steel sheet, the quality of door installation, and a number of other factors. But in a critical situation, in the absence of a choice, any methods are good.

El/discharge. It is enough to bring the source (piezo lighter, stun gun) to the “socket” for applying the key, the automation can work and break the power circuit of the magnetic lock. After this, the door will open easily.
Jerk. Installation of an intercom requires strict adherence to a number of rules. In practice, they are not always observed. You can try to press down on the steel sheet and then sharply pull it towards you. Sometimes two or three attempts are enough and the door will open. Naturally, you will have to apply a fair amount of force, and therefore this method is recommended only for men.
Hit the door. You need to hit in the area where the magnet is located. If the device has already partially exhausted its resource, or was installed incorrectly, the force of attraction of the canvas may weaken. Then you can open the door with a strong jerk. One of effective ways when solving the problem of how to open the intercom with Metacom without a key.

If there is no shortage of time, there are other options - call your neighbors (they may not hear the intercom buzzer). As an option, wait until a person coming out of the entrance opens the door from the inside (or someone who has a key comes up).

Methods for unlocking various systems

*B – call button (key)

For any of the schemes, the role of the “magic key” is played by a specific intercom code, that is, a combination of symbols and numbers. It is different and depends on the model of the protective system.

Metacom

B + (No. of the first apartment in the entrance) + B. After the COD letters are displayed, the combination 5702 is dialed.

The lock, if the factory metacom codes have not been changed, should be demagnetized. If it doesn’t help, you should move on to other options.

1234 + V + 6 + V + 4568
V + 1+ V + 5702
V + 5 + V + 4253
V + 6 + V + 4568
65535 + V + 1234 + V + 8
65535 + B + 7418378
B + 1803
B + 1234567

To open the Metacom modification MK-20T/M intercom, the following master codes are used.

V + 27 + V + 5702.
B + 1 + B + 4526

Forward

Inexpensive and reliable Forward systems do not differ in circuit complexity; open with several codes:

K+1234
K + 557798 + K
123 + * + 2427101
2427101

Digital

Opening a cyfral intercom without a key is more difficult - there is no single encoding for all models.

For apartment numbers with “round” numbers (100, 200 and so on):

B + Apartment No. + B + 2323 (options – 7272, 7273).

For intercom series:

“M” – 07054. If it doesn’t work, then B + 41 + B + 1410
“CCD” (model 2094/1M) – B + 0000.

When ON is displayed, press button “2”. The appearance of OFF symbols on the display of the control unit indicates reprogramming of the intercom. In this case, any further combinations are meaningless; the door will not unlock.

"CCD" (model 2094/M) – 0000 + V

After “COD” appears, buttons 1 to 6 + B are pressed in turn.
The second option is 456999 + V.
The third method is 123400 + V. After displaying “F0” + 601

Eltis

Opening the eltis intercom is not difficult - it is one of the simplest systems; There are few options.

V + 100 + V + 2323 or 7273

You can solve the problem of how to hack an Eltis intercom using codes that apply to Digital models. Which ones are suitable is tested by practice; For different Eltis series, only one, maximum two combinations are suitable.

Visit

"Visit" intercoms are available in different modifications, but the algorithm of user actions, regardless of the block series, is the same. There are some nuances associated with the absence of some specific buttons, so you will have to navigate according to the situation.

* + # + 423
67 + # + 890
12 + # +345
* + # + 4230
“#” + 999. After 2 intermittent signals, four digits are dialed in a row, from 1 to 4. Options for the last combination are 0000, 6767, 12345, 3535, 9999
“2” + short wait + “#” + same + 3535

There are no “#” and “*” buttons on individual CU panels. In this case, try the combination “C” + “K”

Advice. For models without a display, you can try pressing “1” and then dialing any combination of 4 digits. The probability of the electronics triggering is small, but if there is no other way out, this is an option.

Factorial

You can open a factorial intercom without a key using several code combinations.

A set of numbers from 1 to 6
Code 000000
"Five". After “180180” is displayed, press buttons B + 4 + B

Marshal

The first thing to do is determine the number of the last apartment in a given entrance and add 1 to this number. For example, 20 + 1 = 21.

Techcom

One of the devices that is very difficult to open with a set of numbers and symbols without a key. Therefore it will be needed; Suitable for any series of Techcom intercoms.

Working with buttons “0”, “1”, “6”. They are pressed simultaneously, then released one by one in the sequence 0 – 6 – 1.
After the signal, enter code 4321
B + 3 + B
The key is presented; perhaps it will demagnetize the lock and the door will open.

Note

On steel doors other models of intercoms are also being installed - “Stroymaster”, “Kron”, “Arcades”, “Secret”, “Pirce”, “Komaks”: and that’s not yet full list protective systems. Judging by the information on the Internet, almost all of them cannot be hacked by guessing codes.
On sale “from trays” there are so-called universal master keys (the same keys with special firmware). They open almost all doors, regardless of the installed electronic system. In addition, they are inexpensive - from 100 to 150 rubles, and therefore there is a great demand for them. The plus is obvious - it’s very convenient. But not everyone understands what the systematic use of these keys leads to. The result of such a “service” is incorrect operation of the intercom with subsequent failure of the control unit. And repairing its electrical circuit, especially replacing the unit, is not cheap.

It is better to prepare for possible troubles in advance. Therefore, it is worth contacting the intercom service company and finding out the codes for opening. If its employees refuse an oral request, make a request in electronic (written) form, appealing to the relevant law (PZPP; latest edition of 2017): the consumer has the right to receive all information about the service or product provided.
