A phone program that can open an intercom. Useful tips on how to open any intercom without a key. Opening the Eltis intercom

In the last article it was not possible to cover all the options for opening an intercom, and I had to write a second article in which we will look at other intercom models. We will help you get into your entrance if you accidentally forgot your keys at work or at home.

In this article we will consider the following options for opening intercoms:

1. Open the intercom Laskomex AO-3000.
2. Open the intercom Build Master.
3 . Open the Techcom intercom.
4 . Open intercom Berkut LS2001.
5. Open the Polis intercom.
6. Open the Keyman intercom.
7. Open NFC Intercoms.

How to open the Laskomex AO-3000 intercom?

If you are wondering how to open the Lascomex intercom, then you should know that Lascomex 3000 is a cipher lock that can be opened without having specialized knowledge, like some other intercoms with a similar system. To access system parameters castle, you need:

Press the keys with the image of a key and “0” four times in turn;
. enter the password pre-set by the manufacturer to enter the system parameters (standard for all) - 6666 (the screen will show “SSSS” - indication of entering the setup menu);
. when the “P-” icon lights up, enter the number 8 (the installation code to open the door or to service the power system of the code lock).

If you carry out such manipulations and lock the door using this lock, then within 45 seconds you will have access to the house.

How to open the Stroy Master intercom?

Sometimes it happens that the technicians who install intercoms change standard password from the manufacturer and then it will be quite difficult to get into the premises, but if this does not happen, then the following combinations should be entered in turn:

1234, 6767, 3535, 9999, 12345, 0000, 11639. Maybe today we were lucky, and one of the options did work, then press “B”, open the door and then press “C” (so that the system continues to work as standard mode).

How to open the Techcom intercom?

In order to open doors with intercoms from this manufacturer, you need to press in turn (without releasing the keys) the numbers 1 6 0 (possibly 2 5 8 in another case *) and release them in the same sequence, but vice versa - 0 6 1 (or 8 5 2 respectively*). A signal will sound and the “----” indicator will flash, which will mean that you are ready to enter the password “4321” (possibly 1234 *) (standard code for this brand). Next, press “B”, then “3” and “B” again - the door will be open.

*- For new version intercom software firmware.

How to open the intercom Berkut LS2001?

This version of intercoms inherited the bypass paths from MetaCom and Digital. In order for the door to open you must:

. “1” - “key” - “5702”
. “100” - “key” - “7272” or “7273” (the first variation of the code opens entrances with apartments from 1 to 127, and the second - apartments from 128 to 256)

How to open the Polis intercom?

It is also a Reinmann 2000 brand intercom (it was like this until 2001, after which it was improved). It's easy to hack, but a little long. To do this, enter: “key” - “987654” - “123456”. The letter “P” will appear on the display, press the number “8” and the entrance will open for 45 seconds.

It is possible that this intercom is a new type Polis-51TM or Polis-52TM (both without a digital display), then you need to know the individual code. If you don’t have one, it’s easier to jerk the door sharply, use a special mechanical key, or use a regular shocker to short-circuit the electronics of the lock (there is a possibility complete blocking door and then it can only be opened with the help of an installer).

How to open Keyman intercom?

One of the safest intercoms in terms of bypassing a special code or identifier. The probability of hacking such an intercom is extremely low - approximately 5%. But there is still a chance that when installing it, the technicians were lazy/forgot/deliberately left the factory codes and identifiers. To access the door, we carry out the following manipulations with codes:

. “Call” - code “100” - password “789” - sound signal - standard settings password “123456” - number “8”
. “Call” - “170862” - sound signal - number “0”.

It is necessary to mention the reliability of the security software of such intercoms, since they are perfectly protected. Their firmware will block further actions leading to unauthorized access to the intercom settings and subsequent opening of the door.

How to open NFC Intercoms?

There are intercoms that work using NearFieldCommunication technology, NFC (“near field communication”, literally translated). Intercoms based on the reception and transmission of a network signal (data packet) can only be opened by the operator of the main management unit - he is also the owner of the apartment or the concierge.

When a signal is received from the card or key receiving panel to the control module, the signal processing server determines whether the received request to open the door is valid, and only then unlocks the door lock. This means that they can only be hacked from the inside and with a computer or tablet/smartphone. Such intercoms function thanks to IP telephony: opening the door using a code/password/sequence of manipulations with numbers and auxiliary keys will not work at all.

Video. How to open Keyman intercom?

Everyone knows that utility workers open the intercoms of a huge number of houses without carrying around a huge bag with keys to all these devices. They use the entrance to the programming mode, in which opening the door is far from the most complex function.

Manufacturers do not pay due attention to complicating access to the program mode, as a result of which an ordinary person who does not have special professional skills in programming electronic devices, it becomes possible to provide keyless access to the entrances of residential buildings equipped with intercoms.

Opening the intercom Visit

If the factory settings are not changed, there are 4 code options: *#423; 12#345; 67#890; *#4230.

To access using the service menu: #999. After two intermittent signals, enter: 1234 (standard), if there is an error, enter: 0000; 9999; 3535; 12345; 6767. The access signal is one sound, the refusal signal is two sounds.
A way to access the service menu using three buttons. Press “2” (wait a couple of seconds), “#” (another couple of seconds), “3535” - then the door opens.
After pressing “*”, the program mode is exited.

Opening the METAKOM intercom

Three ways to open METAKOM intercoms:

1) Press the call button, then dial the number of the first apartment in the entrance and press the call button again. The letters COD should appear on the display, dial the numbers - 5702.

Recently, they have been widely used. These devices work as an entry system, allowing only those who have the appropriate key to enter the house. There are times when the key is forgotten at home, lost, or simply fails. Naturally, the question arises of how to get into the house in this case.

There are many ways to open a door using special codes or universal keys. Despite the fact that there are such methods of opening doors, many users are interested in whether it is possible to open the intercom with a telephone.

It turns out that such a possibility really exists and it is realized through special technology, which is called NFC. Below we will discuss the main aspects of this wireless technology and under what conditions it is possible to use using NFC open the intercom.

What is NFC technology

NFC is wireless technology, with which you can make contact between two devices. NFC is a continuation of the well-known contactless data exchange technology RFID.

The difference is that RFID tags can be read from a distance of several meters, while NFC tags can only be read from a distance of no more than 10 cm.

When transmitting data using this technology, an initiating device and a passive module are used. The device generates a magnetic field that affects the passive network, transmitting data.

To transmit data using NFC technology, special coding is used, which differs in modulation index, which depends on the data exchange rate. It is important that NFC devices can support two processes in parallel - transmitting and receiving data.

Thanks to this, these types of devices can monitor the magnetic field and detect inconsistencies if the received signal does not meet the required parameters. Such capabilities of NFC technology are actively used for contactless reading important information in various systems.

There are three main ones:

Emulation of cards and other access elements for contactless identification of an object. This method is actively used to emulate plastic cards on a smartphone, which allows you to make contactless payments using your phone. The data that is read from the phone is not stored in its memory, but in a special chip that is supported by the phone system. To be able to emulate a card, the phone must support NFC technology. In addition to card emulation, this technology allows you to copy the intercom key to NFC phone and use it to open intercom locks.
The second area of use of NFC technology involves the use of devices in the form of scanners of corresponding NFC tags, which will allow access to various data. Recently, these types of tags have been intensively used instead of conventional barcodes.
The third option for using NFC technology is called “Peer-to-Peer”. It provides the ability to exchange data between two devices. For example, you can support wireless data exchange between two devices that have NFC tags.

Is it possible to open an intercom using a smartphone with NFC?

To look for an opportunity to open an intercom using a telephone, it is important to understand whether such a possibility exists technically. Firstly, the installed intercom must provide the ability to use NFC tags to control its operation.

These must be special devices that support the appropriate NFC technology for reading information that allows access to the facility. NFC intercoms can only be opened using the appropriate tags; in this case, it will not be possible to gain access using passwords or special codes.

Secondly, not every phone or smartphone is suitable for working with this type of intercom. The phone must also support NFC technology in order to be able to exchange data with the electronic intercom module. To record tags on your phone, you should use a suitable software which is suitable for operating system installed on your smartphone.

Conclusion

If you want to control access to your home through your mobile device and store the intercom key in your smartphone, you should choose exactly the intercom that supports NFC technology. You should also make sure that the NFC tag with the intercom key code can be recorded on the phone. Then you won’t have to carry the keys to the intercom with you, but will be able to get by with a smartphone that is always at hand.

Many of us are familiar with the situation when we need to enter a house, but due to the lack of a key to the intercom system, this becomes impossible. Of course, you can try to call your neighbors or wait until someone comes into the entrance. However, there are ways to get inside without the help of other people. We will tell you how to open the intercom without a key.

When is tampering with the intercom system considered a crime?

Opening an intercom without a key can be considered by law as illegal actions in two cases:

when you enter a house with malicious intent, for example, to take possession of someone else's property. From the point of view of the Criminal Code, such actions are considered hacking and entail appropriate punishment (fine or imprisonment for up to 6 years, depending on the severity of the crime);

if during the opening of the intercom you cause damage to it, due to which it ceases to function. Such actions can be regarded as damage to property, and the degree of punishment is determined depending on the amount of damage.

So think three times before open the intercom without a key. Perhaps it’s better to turn to your neighbors for help?

Universal ways to open an intercom without a key

If you can’t wait for help from anywhere or from no one, then all you have to do is resort to one of the methods that helps you cope with the intercom system without having a key.

Intercom, or intercom system - electronic system, consisting of devices that transmit a signal from the calling unit to intercom. The intercom system is divided into single-subscriber and multi-subscriber devices. It can be equipped with automatic locking devices (ALDs) of both electromechanical and electronic types. Wikipedia

The main thing you need to know about intercom locks is that they are magnetic. They do not have the usual latching pawls of mechanical locks; the door is held in place by the force of a magnet. Therefore, you can open such a lock using force, but it is important to correctly distribute the effort.

You should rest the toe of one foot against the static door, grab the handle of the opening door with your hands and sharply pull it towards you. We don’t recommend simply pulling: the force with which the magnets hold the door corresponds to a weight of 400 kg. Think for yourself: can you move a stone with such a mass?
Another effective way to open an intercom is to purchase a universal master key. It can be suitable for all models of locks or intended for intercoms of a certain type trademark. In the first case, the percentage of openings will be low, in the second - out of 100 attempts, 85-99 may be successful.
There is another method that can also help. Call any apartment, introduce yourself as a utility service employee (a plumber, a telephone operator, an Internet communications or satellite TV repair specialist) and ask to be let into the entrance. If you come across a gullible person, you will get into the house without any problems, but cautious and suspicious tenants will not let you through.
A piezo lighter can also help in such a situation, but, as experts who have already used it write, this method does not always work. The piezoelectric element must be applied to the place where the key is usually applied and current must be passed. If you're lucky, the door will open.

Since the power supply for intercoms is the electrical network, the lock can temporarily malfunction by making short circuit. It is enough to short-circuit the light bulb at the entrance. But keep in mind: not all residents will react to such an act with understanding.
Touch-sensitive models of intercoms are more sensitive, and therefore can be unlocked by exposure to low temperatures. Apply ice or snow to the screen, and after 10-20 minutes the lock will turn off.
If you intend to regularly visit a house with an intercom system, try to “deceive” it in this way. Apply several layers of tape to the magnet, leaving a small contact area untouched. Thanks to this, the lock will work as usual, but opening such a door will be easy - you just need to pull harder.

How real is it? open the intercom using your phone, watch the video:

Codes for intercoms “Visit”, “Metakom”, “Tsifral”, “Eltis”

Open the intercom without a key you can using universal system codes. They are there in case the installer needs to gain access to the lock. We have collected instructions for their application to the most common intercom models.
