Information on opening intercoms

As you know, to set up an intercom you need to gain access to the programming mode. This is usually done by typing the password on the numeric keypad. After entering the installer mode, the specialist who dialed the code has the opportunity to both open the door with the intercom and change any system settings without opening the door.

It is this part of the system that manufacturers have devoted Special attention. However, the implementation of security system control is not always reliable, which allows you to both open an intercom without a key and hack into intercoms of any brand.

This happens most often not because of manufacturer errors, but because of laziness or inattention of the installer. Service codes of intercoms, or - as they are also called - secret codes of intercoms, are set by the manufacturer and are the same for all models. Installers do not change these codes when installing and configuring the system, which allows, in most cases, to open intercoms without a key or the use of special equipment.

Let's make a reservation right away: this is not a FAQ on hacking intercoms, which contains all the intercom codes. The universal reference book that we offer in this article contains only those codes that allow you to simply open the intercom without a key. We will not provide master codes for intercoms used to change system settings, just as we will not reveal some other secrets of intercoms.

And the main thing is for each of the readers to clearly remember: opening an intercom if necessary is an acceptable matter, and hacking an intercom for personal gain is punishable according to the criminal code. So if the main purpose of searching for material on how to hack an intercom was precisely such intentions, then at the same time look for the latest edition of the Criminal Code of the Russian Federation.

In the article we will consider information on opening intercoms of the following types: Barrier II, IIM and 4; VIZIT ( different models); Cyfral (various models); Eltis; METACOM; Rainmann; DomoGuard; Blink; T-Guard.

But before we begin, there is one more thing to mention: universal code for an intercom of any type - this is a fiction; each manufacturer indicates its own code for opening the intercom. How to find out the intercom code? If the installer did not consider it necessary to change the master passwords, then the descriptions below will help to do this. Otherwise, you need to contact your installer for the code.

Hacking Barrier II and IIM intercoms

An ancient Soviet intercom of the “Barrier” type with a mechanical lock and a flat magnetic key can now be found no more often than a mammoth. But anything can happen, and such an intercom may well be in some equally ancient house. For models 2 and 2M there is an unchangeable opening code - 1013. But, in principle, the intercom opens without problems with a pair of small magnets, which you just need to move around the area to apply the key.

Barrier - 4

The fourth model of this type of intercom is single-user; it was installed in entrances with concierges. Therefore, it will not be possible to type a permanent code, but you will have to tinker with magnets until the bitter end. The key of such an intercom contains three magnets.

How to open VIZIT intercom without a key

Visit intercoms are a little more difficult to open. The codes on them are significantly diverse. Often the * and # keys are missing from the keyboard, instead the C and K keys are used, respectively.

If the standard settings of such an intercom have not been changed by the installer, then the door should open when *#4230 or 12#345 is entered. Opens recently installed intercoms with visit code *#423 or 67#890

How to hack intercom vizit through the service menu: dial #999 – this is to enter the service menu, wait for two short beeps, then enter the master code (default 1234). The visit intercom, which is being hacked, should respond with one short squeak. If you entered an incorrect code, the signal will be two-tone. In this case, you can try standard variations of master codes - 6767, 3535, 9999, 0000, 12345, 11639.

After entering the service menu, you can either open the intercom visit or perform a number of somewhat more complex operations.

So, combination 2 - pause - # - pause - 3535 - command to open the intercom door without a key.

Button “3” is configured to program keys for the intercom. After pressing key 3 in the service menu, you need to attach the key to the reader, press # and wait for the beep. That's it, the key is entered into the intercom memory.

Button 4 erases keys from memory.

* - exits the current mode.

# - used to confirm changes.

It will be a little more difficult to open the “Visit” BVD-3xx intercom - without a display and indication LEDs. To open the door, you need to press 1 in the service menu. However, hacking the intercom is not always successful. The visit will be successful in the case of the BVD-34x model (with a left-sided receiver).

How to open the Cyfral intercom

To open the Cyfral intercom you need:

a) if there are apartments in the entrance with numbering divisible by 100 (100, 200, 300, etc.), then the code must be entered as follows: call key (code 1) call key (code 2). In place (code 1) you need to enter the apartment number divisible by 100, and in place of code 2 - 2323, 7272 or 7273.

b) for intercom models with the letter “M”, you can try the code “call key + 41” or “call key + 1410”. Sometimes the door opens if you simply enter 07054.

The CCD-2094.1M intercom needs to be opened differently. You can distinguish it by a burning or flashing line on the screen. If you dial the code “call + 0000”, either the door will immediately open or you will enter the service menu (ON on the screen), then you need to press 2, after which the door will open. If OFF appears, the Quick Entry mode is disabled. This means that an installer who has been installing Digital intercoms for a long time was working. Accordingly, he changed the access codes.

Intercom codes Cyfral CCD-2094M

To open an intercom of this type you need to dial the code “0000 + call key”. The display should show “cod”. You need to enter the code 123456+“Call” or 456999+ “Call”, sometimes the combination 123400+ “Call” is used. We wait two to five seconds. If “f0” appears on the display, then access to the system menu is open. To open the door, you need to enter code 601.

If you want to visit this intercom (or rather, its owners) regularly, then it is better to enter your own key into the intercom memory, suitable for the Digital intercom. To do this, press the call key and keep it pressed until a message appears on the display indicating that you have entered the service mode. Then press “five” and enter the number of the existing apartment in the entrance. The display should change to TOUCH. As soon as this happens, apply the key. If you come across a model with an old optical key, then instead of the apartment number you need to dial 600, then insert the key and press the call button.

How to open the Eltis intercom

Eltis intercoms, the codes for which are not varied, are quite easy to open. There are two options for service combinations that will ensure “neat hacking” of the Eltis intercom: “call key 100 call key 7273” or “call key

100 call key 2323". If hacking the Eltis intercom does not succumb to such combinations, you can try options from Digital intercoms.

How to open the METAKOM intercom

Hacking a Metacom intercom is done according to the following scheme: you need to press the call button, then enter the number of the first apartment in the entrance and press call again. “COD” should appear on the display. After which you need to enter the actual code - 5702. If this method does not work, then try the combinations 65535 + call button + 1234 + call button + 8 or 1234 + call button + 6 + call button + 4568.

And also about how to hack the Metakom MK-20 M/T intercom without dancing around the keyboard. In principle, this model does not and will not have a system of protection against the use of master keys. Therefore, if you bring a “tablet” without firmware to the intercom reader, it will automatically enter programming mode. If you don't have a tablet, you can persuade it to open using the numeric keypad. The Metacom brand MK-20 M/T intercom code can be “call button + 27 + call button + 5702” or “call button + 1 + call button + 4526”.

How to open a Rainmann intercom

Reinmann 2000 models, as well as those intercoms of this brand that have a dot on the left on the display, can be opened as follows:

Press the “key” button on the numeric keypad and enter the code 987654. The reaction to this operation should be a double squeak. Then enter the code 123456. The letter “P” should appear on the screen, which indicates that you have entered the service menu.

4 - lock the door;

6 - turn off the intercom;

8 - open the door;

How to open the DomoGuard intercom

DomogarD intercoms are a little more difficult to open. You need to hold down the C button and wait for the squeak. Then quickly enter the service combination - 669900, press the call button and enter the apartment number one unit larger than the last one in the entrance. The intercom will respond by displaying “F—“ on the display. It means that we are in the service menu. To open the door, dial code 080. To enter a new key into memory - code 333, to disable the door lock - code 071

How to open the T-Guard intercom

Hacking this intercom is the simplest of those proposed. Press “call button + 00000 + call button twice.” The main thing is to do the last two clicks very quickly. The door is open.

How to open the Factorial intercom

The system of these intercoms is similar to Digital. The service menu is entered after the 6-digit Factorial intercom code is dialed. Usually this is 000000 or 123456. However, installers claim that hacking the Factorial intercom is practically impossible, if only because the Factorial intercom code must be changed during installation - this is one of the mandatory service settings. But you can try this combination - press the “5” key until a service message appears on the screen (3-5 seconds), then dial 180180 + call key + 4 + call key.

How to open the Blink intercom

This is the only single-user audio intercom widely used on the Russian market. It has neither a screen nor a numeric keypad and is usually installed in houses with a concierge or in private cottages. Therefore, service combinations will not help here. An ordinary D9-0.1 battery will help - “Krona”, “Corundum” and the like. The European type of such battery is 6F22. So, under the bottom panel we find false bolts of a strange shape - they exactly correspond to the “Crown” connector. We attach a battery to them - and voila, the intercom is open.

Manufacturers of entrance intercoms install special codes on their devices that allow you to open the door without a key. Such combinations are used by maintenance technicians. Secret codes are not disclosed to strangers, but in some cases of force majeure this is necessary. Knowing how to open an intercom without a key, you can save a person in trouble or prevent a crime from being committed. After reading the guide below, you will understand how this is done. Use the knowledge you gain wisely, since using codes for personal gain is a criminal offense.

Ways to open a door with an intercom without a key

Each company that produces electronic door locks uses its own individual access codes. They work flawlessly if the technician leaves the factory settings during installation. In all other cases, the process of opening the door without a key becomes significantly more difficult. This requires entering the settings menu, which is not easy to access. However, many locks in our country are installed without changing the password, so in case of emergency you can open the door with an intercom without a key. Let's look at this in more detail.

Cyfral

Door locks from this manufacturer differ in a number of features. To understand how to open a Cyfral entrance intercom without a key, use the following recommendations:

1. At the entrance where there is an apartment with a round number (100, 200, etc.) the following combination is used: “call + code1 + call + code2”. IN in this case“code1” is the apartment number from this entrance, a multiple of 100, and “code2” is the code of the device itself (23 23, 72 72 or 72 73).
2. Devices marked with the letter “M” are opened with the combination “call + 41 + call + 14 10”. If this doesn't work, try entering "070 54".
3. Any CCD-0294.1M model with standard settings will open when you enter the “call + 00 00” sequence. If the message "ON" appears, press "2" and the door will open. The answer "OFF" indicates that the passwords have been changed and you will not be able to open the door without a key.
4. Models CCD-2094 and CCD-40 open without a key using the combination “00 00 + call”. After entering this sequence, the message “cod” appears. Next you need to enter the secret password “123456 + call”. If that doesn't work, try "123400+call". In some cases, devices of this model may show an "f0" message. If you see it, enter the numbers "601".

Keyman

Breaking the security of this manufacturer is a real problem. At the moment, two working combinations are reliably known: “K + 100 + 789 ... sound signal ... 123456 + 8” and “K + 170 862 ... sound signal ... 0”. Using them, you can open 2-3 Keyman doors out of ten. If the above methods do not work, you will not be able to break into the door without a key or chip.

Marshal

Modern models of this company open with serious difficulties, since during installation they use house and apartment numbers as an access code. For all old access door locks, a simple combination works: “number of the last apartment, increased by one + K5555.” In addition, some Marshall models open without a key with the password “240 361”.

Eltis

You won’t have to think long about how to open the entrance intercom from this manufacturer without a key. One of two standard combinations will help you:

• “call + 23 23”;
• “call+ 72 73.”

Metakom

If, when installing the door, the installation team did not receive instructions to change the access code, one of the three schemes described below will help to open the lock from this manufacturer:

1. “bell + number of the first apartment in the entrance + call.” After this, enter the standard Metacom password - “57 02”.
2. “655 35 + call + 12 34 + call + 8.”
3. “12 34 + call + 6 + call + 45 68.”

Opening the METAKOM MK – 20 M/T model is carried out in a different way. It uses one of two sequences:

• “call + 27 + call + 57 02”;
• “call + 1 + call + 45 26.”

Forward

Finding the secret master code of the Forward device is not so easy, since in most cases, during installation, combinations associated with the address are installed. The components can be house and apartment numbers. In some cases, the encoding includes the telephone number of one of the outermost (first or last) apartments in the entrance. However, there is a standard encoding that will work if the technician did not change the password during installation. Write it down for yourself: “24 27 101.”

Factorial

The security system of this brand is in many ways similar to Cyfral access door locks. They are widespread in St. Petersburg, but local experts cannot say exactly how to open a door without a key. A single password exists, but it rarely works, since a unique code is almost always entered during installation. This is necessary to ensure that residents of the entrances do not use intercoms for free. However, you can try. Dial the following: “00 00 00 + 12 34 56”. If it doesn't work, try the combination "5 + 180 180 + call + 4 + call".

How to find out the universal code from an intercom

A universal code for all intercoms is a myth. Each company programs its devices so that they open with a couple of secret combinations. If, when installing the door, the installers do not consider it necessary to change the codes, everyone will be able to enter the entrance without a key. Master codes are known only to service employees, but they keep them secret and have no right to disclose them to anyone. However, there is alternative solution– universal key for intercom. It is inexpensive and works almost flawlessly. With it, you don't have to remember long codes that work every time.

Video: codes for opening intercoms

Watch the video below to understand how to use the intercom if you don't have a key. There is nothing complicated about this, you just need to enter the combinations correctly, listen to the sounds and carefully look at the display. Follow the recommendations from the video and you will understand how to hack the intercom at your entrance. This knowledge can be useful if one of the residents urgently needs help.

At many entrances, intercoms are now installed at the doors; they prevent unwanted characters from entering the front door: persons of no fixed abode, drug addicts and representatives of the criminal world. But at the same time, it also happens that it is difficult for the residents themselves to overcome the closed door, for some reason they are left without a key.

What is the code like?

There are times when you need to find out the code from the intercom. For example, many people have experienced a situation where the key was lost or forgotten at home. Then you have to wait for someone with your key. But you can do it differently. How to find out the cyfral intercom code?

If you have a cyfral intercom, the opening code will most likely be universal.

Each of the intercoms has built-in menus designed to encode keys, as well as assign codes to apartments and other parameters. There are also universal access codes. These codes are set identically at the factory. If you have a cyfral intercom, the opening code will most likely be universal (“1234”). It happens that the company that installed the intercom did not change this key for some reason, this code will do. This happens quite often and it even happens that the cyfral intercom code can match any other intercom of other brands and manufacturers.

Intercom Cyfral CCD 20

If you need to find out the code for the Cyfral CCD 20 intercom, you can use the password “123456” generally accepted for this design. The code used for access is the same as everywhere else (“1234”). And also the code for the table with the setting encoding “000”. It allows you to set a doorbell to a specific number. This is usually the subscriber's apartment number. You can also use it to register an electronic key code for a magnetic lock.

Intercom CCD-2094

Intercom code CCD-2094. A door with such a lock opens like this: dial “B” and “0000” and after that the door will either open or the service menu will open (the code image on the screen will change to “ON”), then you need to use the number “2” and then open door. Although the value “OFF” may be displayed, this means that the quick entry mode is turned off. The remaining passwords for controlling the intercom in this case were also changed.

If the universal cyfral intercom code does not work, you need to use the following combination: enter the numbers “0000”; when the word “ON” appears, press “2”. After that, when “Cod” appears, enter the password “123400”. If this set of numbers does not work, enter the passwords “123456” or “456999”. If the password is entered correctly, the message “FO” will be displayed. In this case, you should use the combination “6” “0” “1” and then the door can be opened.

You can also register your own key in the intercom memory. To do this, you need to press the “B” key and hold it until a message appears on the display indicating that you have entered the service mode. After this, you can enter the electronic key into the intercom memory. To do this, press the “5” key and press your apartment number. The display will show “TOUCH”. Then you can apply the key.

These recommendations may not always work. A responsible company for the installation and maintenance of intercoms tries to immediately change the access codes for managing the lock settings to their own to prevent unauthorized actions with the device. But in more than half of the cases, it turns out that the installer did not change the factory settings, which makes it possible to penetrate the door with such an intercom. Usually this is done by companies that do not plan to maintain this front door in the future; they simply installed a door with an intercom and that’s it.

Cyfral is a domestic research and production enterprise that has a full line of classic security systems: from standard video and audio intercoms and intercoms to power supplies and electromagnetic locks.

The company has its own plastic molding, mechanical and assembly workshops. The company's product descriptions honestly and openly publish some of the legal information, which allows this company to be trusted and confidently cooperate. It has not been on the market for very long: it became an adult only in 2016.

But, like all other intercom systems, users of this brand are not insured against the loss or breakage of their own keys; the need to enter the house did not bypass residents under the auspices of the protection of this system.

Codes and everything about them

To open the doors of the Digital intercom system, you need to know the following universal codes:

• В-100-В-7273;
• В-200-В-7273;
• В-300-В-7273;

There is a single code for system operation:

0000-V. Wait for the inscription “Cod”, enter 12345-B. If everything is correct, the message “F0” appears, and then you can work with the service menu, for which there are the following commands;

65535-В-1234-В-В-apartment number-В-7. This code records the key to a specific apartment;

65535-В-1234-В-В-apartment number-В-7-0-111. Deletes all keys recorded for a specific apartment;

65535-В-1234-В-9-9. This is a recording of a new master key, and the prefix -0-111 at the end allows you to delete all existing master keys in memory.

Important: most of the mentioned codes for system intervention are used on freshly installed intercoms, that is, only those released from the factory.

Installation technicians always change them during installation, so many operations have to be carried out at random, but practice shows that the “ ” and “ ” commands can readily be used.

Conclusion

Perhaps, even though “Digital” is a rather secondary product, imitating “Visit” in many respects, what cannot be taken away from it is its conscientiousness in the quality of work and the presence of beautiful codes, which are a pleasure to enter. Description of company products
