Independent manufacture Cranema immobilizer In most modern cars An immobilizer with a radio frequency label is applied (RFID - Radio Frequency ID) in the key. Its code is read using a frame located around the ignition lock socket. Tags, as a rule, passive. Those. Power supply is obtained from the magnetic field "pumping", induced in the tag antenna. Basically uses the frequency of 125 kHz. In some cases, the frequency is 13.56 MHz. In contrast to the antenna of the transceiver, which is a frame, in a label from compactness outputs, use ferrite antenna (thin wire wrapped on a rod from a high magnetic permeability material).

When connecting a remote engine start system, you need to bypass the implementing system of the immobilizer. To do this, you need the key prescribed in the car (label, chip) and the correctly connected crossover in which the key is invested. Passage in normal mode is disabled, connected only at the time of the remote start (or autorun). Usually, the sparkler is a box with an antenna frame and relay. And if not purchased, it is easy to make it yourself. In some cases, it is even preferable, because It will be possible to make a much more compact design, which is much easier to hide very deeply.

1. We make a frame on the ignition castle. To do this, we make a mandrel (for example, from cardboard) of the desired diameter, under the ignition lock. We need our frame to fit exactly there. On the mandrel we wake the cooler tape or tape (it thinned) sticky side up.

We wind the winding wire, 20-30 turns with a diameter of 0.1-0.3 mm. The wire can be taken from the coil of the automotive relay. One relay you can sacrifice one coil enough for several crowders. We do so carefully we need compactness. Cutting the edge of the tape, we ride it on our winding.

Excess the tape gently cut off with scissors. The annular frame is obtained, quite thin.

Then we ride the wire and turn the conclusions. Fix them with a tape. Frame is ready.

2. Wash the key or chip In the same wire, the frame of 20-30 turns, soldering the conclusions, closed with a tape.

3. Installation We install the first antenna into the ignition lock casing, and the key with the frame will later need to be hidden somewhere in the car so that the potential attacker has spent as many times as possible in search if he does something at all.

4. Connection Connect the frames and the relay, built into the immobilizer to bypass as shown in the diagram.

Our key will be shown the car only for the distance of the remote start. The wires that our additional framework connect are needed as thoroughly in the standard wiring. They should be as difficult to identify.

5. Nuances Rarely, but there are cases when even the thinnest made frame does not climb into the ignition lock casing. Then you have to include our additional antenna with a key to the gap. In this case, the second antenna in the casing of the ignition lock is not needed at all - we include our winding around the key instead of a regular start-up, switching it to the relay contacts.

In this article, we will tell a little information about the blocks of the immobilizer crossover.

To install the automotive alarm with the autorun function, you need to solve the engine launch task without a key in the ignition lock.
But in the modern car there is anti-theft system - Immobilizer, and the engine does not start without a chip key. There are as invincible crawls of immobilizer, and the usual, about them will be speaking today.
How does the immobilizer cross work and how can a car be laid without a key in the castle?
The ignition lock is an immobilizer antenna, which when turning on the ignition, begins to poll the chip key. The radius of the antenna of the immobilizer is only a few millimeters, which is why it is not enough to just put the chip key into the car's salon - the engine will not start. It is necessary that the key read the key at the time of launch. To do this, make a ready or homemade antenna in parallel with a regular antenna of the immobilizer, which is on the castle. Here is a photo with an example of unsuccessful homemade antennas that are wounded finely wire straight to the standard antenna and grabbed black tape, all this is not aesthetically, very harpko and most importantly - not reliable:

Next task to repeat the operation of the immobilizer's regular antenna on a remote and hidden parallel antenna. In the immobilizer commander, there is a built-in antenna. There and placed chip or autorun key.
The general view of the immobilizer speaker is a small plastic box with connectors:

Inside the module of the immobilizer, there is a board, a pair of diodes, a relay and antenna for reading the key.
It is in the rounder that is placed chip or a whole key. And by the way, it is not always done correctly. We constantly warn you that you do not need to hide a whole key, and more correctly make a separate, additional immobilizer chip.
But this is the floor of the case, now you need to place it correctly in the antenna.
The antenna in the commuter module is a train, it is in it that the chip or chip key is placed. For the maximum resistant reading of the chip, it should be inside the antenna from the loop and across the turns of the antenna.

But there is one important subtlety: Ideally, the antenna coil should be a cylindrical shape, otherwise the chip can be read unstable.
This is how it is undesirable to use an antenna in the side of the corporator, of course, in ideal conditions, the chip will be read, but at low temperatures of the already characteristics of chips deteriorate, and the incorrect form of antenna and can make autorun it impossible at all:

It will be right when placing a chip into a traizer block loop antenna, give it a form other than flat and close to cylindrical. To do this, it is convenient to place a chip into some permeable material with a shape, such as foam, foam rubber, etc. ,.

Here is an example of the correct form of the immobilizer trailer loop.

And here is another example of "savings": instead of the cross, simply use the key to which the wire is wound and fastened with a tape.

The quality and reliability of such a substitute for the immobilizer is doubtful, and it looks terrible.

When using an immobilizer of high-quality immobilizer in a corporate partner, without battery chips, as well as their correct location, guarantees the launch of the car in any conditions. And the manufacture of additional keys and chips, and not the donation of one of the work keys of ignition will save from cases and problems associated with opening cars.

The immobilizer crossover module itself is connected to the main block of alarm and parallel antenna, is removed and hiding inside the car's cabin, preferably in a secret, hard-to-reach place.
Addition: The following information is incorrect!
Just do not mistakenly think that if there is a chip or key in the crowder, then the car can be made by a simple key - a simple blank without a chip. Not! The immobilizer commander module is turned on and polls the chip placed in it only at the time of the remote launch from the alarm key fob. For this, there is a relay inside the commander. And even if the car is headed with autorun, then without a valid key with chip, the car will not go anywhere. Since sowing in a car, started with autorun, you need to turn the correct chip key in the lock and remove the signaling from the autorun mode. Here at this moment and the key is surveyed in the ignition lock. And only if there is the right key, the engine will continue to work. Otherwise, it will stall.
The end of incorrect information.

The main theme of today's article will be the corporate immobilizer with their own hands. Immobilizer is considered one of the most common and time-tested protection devices. vehicle. So, the submitted article posted answers to such fairly common questions:

How to get around the full-time immobilizer?
What is the corporate immobilizer?
Main types of immo spectrors;
What should be the perfect commander?
Is it possible to make a corporate speaker with your own hands?

basic information

It is called immobilizer electric devicewhich deprives the vehicle to start the engine. Thanks to this complex, not only the protection of the vehicle from the hijacking is ensured, but also the comfort of its use. But there are cases when there is a need to bypass immo. The question of when such a need may arise. The answer is simple, sometimes necessary bypass Immo and most often such a need arises in such cases:

With the hijack of the vehicle;
With loss of keys or breakage of the standard immo;
When installing automotive alarm with auto start.

When an alarm is installed on a vehicle with autorun, you need to run a standard immo for a while, for this launch of the vehicle, and then saving all the possibilities of standard auto protection, to improve the level of protection against hijacking and the normal functioning of systems that are directly related to it. . Usually motorists use several methods of establishing and here are the main of them:

Bypassing the immobilizer of the VATS system;
RFID System Scope Module.

To date, there are a couple of parts bypass staffing immobilizer. When establishing a corporator, be sure to take into account the type installed system Launch vehicle. There are such types of vehicle launch:

The auto start system using the key. In this case, bypassing the key in the ignition lock.
Auto start system using the start and stop key. In this case, you need to carefully connect the key.

On both system running vehicles can be installed. incinual sidepart standard immobilizer. In general, the perfect bypass of the regular immobilizer must comply with certain requirements. So, bypass must comply with such requirements:

The manual must be carried out by automotive alarms and have a universal connection scheme;
Bypag should maintain the maximum number of models of vehicles and car brands of automotive manufacturers;
Bypag should not cancel the actions of the standard immo. That is, the functions of the IMMO should remain the same to protect against theft or illegal penetration into the car salon.
Saving standard immo should not interfere with the use of any full-time keys;
Bypass must have a small cost. It is best if its cost is less than the cost of the key with the chip.

If the RFID system is installed on your car, then reading occurs using the chip antenna, which is located in the ignition key. This chip transfers the low power signal. The immobilizer commander with the submitted system has an elementary connection scheme. This is a standard extension to determine the chip, with ON / OFF function. A similar function corresponds to the corporate speaker or equipment, with which the car engine is launched. Connecting an immobilizer crawling unit makes it possible to manage and disconnect.

How is the immobilizer shutdown? The immobilizer shutdown is a more efficient method, since after that the vehicle owner will no longer encounter similar problems. The immo speaker is a small box in which the reader and relay is located. It is in the bypass module that the spare key is placed. Red wiring must be connected to +12 volts, and black to minus. Next, you need to check the operation of the automotive engine starting.

If the RFID system is installed on your car, the resistance is detected, the feeding resistor, which is built into the ignition key. How is the immobilizer shutdown? To do this, you will need to connect the crossover to the wiring of the VATS system. Cut one wiring and determine the resistance of the resistor. For this you need:

Establish a multimeter and an ohmmeter;
Set the ignition key to the ignition location;
Connect a multimeter and an ohmmeter.

Please note that the accuracy of the readings should be rounded up to two decimal places. Next, it is necessary to choose the desired resistor. In order to include bypass, connect the first end of the cut wire to a closed relay contact, and the second to the general contact relay. Connect the resistor on one side to the open contact, and on the other to the uncut wire. Connect the relay winding with one end to +12 volt, and the other to the alarm. Thus, you turn on the immobilizer bypass.

Independent manufacture of bypass

If you do not have the opportunity to purchase an immobilizer bypass module, then it can be made with your own hands. In order to make it with your own hands you will need only three subjects, such as:

Second key chip;
Wire;
Relay;

You will also need in the manufacture of a traver with your own hands patience for guessing the number of turns. From the very beginning you need to make the coil for the ignition lock and the key with the chip, and then connect them to the relay. In the manufacture of the coil for the ignition lock, you need to wind the wire on the standard coil. The number of turns may vary from ten to fifty. For the manufacture of the coil, a cylindrical subject is needed, the diameter of which is slightly larger than the ignition lock. As a cylindrical subject, you can use Scotch. So, for the manufacture of the coil with your own hands you will need:

Scotch;
Insulating tape;
Transformer wire.

Now consider the coil manufacturing algorithm with your own hands:

Cut the piece of tape, the size of which should be about 15 centimeters;
Mix the tape to the tape, and the sticky side must be at the top;
Mix the wiring over the tape by making about ten turns;
Take up a slightly to the isolate and wrap it up;
Remove the polenta and do more superfluous;
Sold down to the wires wiring and plunder it with a tape.

Next, you need to install the resulting coil on the ignition lock. For the manufacture of the coil for the key, you need to wind the wire on the key, and the number of turns should be within seven to twenty. After that, wrap the coil with a tape and collect the whole design together.

Well no

Immobilizer is a device that provides reliable protection of the car from the hijacking. Even if the attacker tries to turn it off, the elements of the machine will still remain blocked. The importance of the part is really hard to overestimate: some insurers in the absence of it refuse to execute CASCO. But sometimes a protective device can bring trouble to the owner of the car. In this case, the immobilizer commander will be useful.

What is an invincible immobilizer commander for alarm and how does it work?

Today, many car owners set to their transport alarm with the automatic engine warming function. If there is such a system, the start of the motor is remotely.

However, regular protection may interfere with the inclusion of systems: it requires a native key equipped with chip. In order for the alarm to continue the normal operation, the immobilizer crawling module will be required (if you wish the antenna of the immobilizer, it can be connected to the transponder, but in this case the car starts a simple blank).

Module circuit requiring chip: Starline BP 03, Scher Khan (Sherry) BP2

Most cars are equipped with RFID systems (Europeans and Asians) and Vats (Americans). In the first case, to start the engine requires a pre-recorded key with a chip. In the second case, the resistor in the key must have certain resistance parameters. That is, in both options, the car can be run only if there is regular key: hacking or connection of wires will not help.

Cheap Bypass modules are a small container in which the second key is placed (or transponder). When autorun is activated, the system transmits information that the chip is in the machine, and all systems are unlocked.

Module for bypassing the standard immobilizer of this type have straps StarLine BP 03, Sherchan BP2 and others.

Purpose

The STARLINE BP-03 module is designed to automatically shut down the RFID (RADIO Frequency Identi? Cation) when the engine is remotely started.

The RFID system is used on most modern cars. The transponder, the code of which is interviewed when the engine starts the key is built into the standard car ignition key. When remotely or automatically start the engine, this system will not allow the engine to start. To solve this problem, the BP-03 module is intended, automatically transmitting the standard transponder code during the remote engine start.

The BP-03 module requires a spare key with a transponder, which can be ordered from a company supplier of this brand.

Installation

Installing the module is performed in the following order:

Open the central block housing and put the spare key with the transponder inside the flat antenna by fixing it from moving.
Close the center of the central unit.
Secure the block in a secure hard-to-reach place, for example, behind the instrument panel.
Connect the module wires according to the connection scheme.

Connection

Red wire - Plus power, connect to the chain, in which there is a voltage + 12V when the ignition is turned on.

Black wire - Negative control input (70mA). When submitting a negative potential for this input, the transponder regular key code is read. Connect the black wire to the output of the remote start system, providing the potential of the case at the engine operation.

Gray wires - Depending on the configuration, connect to the outer frame antenna, installed around the ignition lock, or wrap the antenna from several turns of the wire, on top of the standard RFID antenna.

Connection diagram 1.

Secure the outer frame antenna on the ignition lock cylinder and connect it to the connector at the end of gray wires. It is important that the distance between the standard RFID antenna and the BP-03 antenna module was minimal.

Connection diagram 2.

The scheme is recommended in cases where the installation of the frame antenna is difficult due to constructive features car. Mock the antenna from several turns of gray wire over the regular RFID antenna on the ignition lock cylinder.

It is important that the distance between the standard antenna RFID and the antenna module BP-03 was minimal.
