What is a grabber is familiar to many computer scientists. This is a program, the purpose of which is to collect information from various sites for the purpose of subsequent placement on their resources. In other words, the program is a thief. With the development of the automobile industry, when a modern car began to resemble a computer on wheels, many motorists had to face the concept of "grabber", or rather "code grabber".
PURPOSE OF THE CODGRABBER
A code grabber is a device designed to deceive a car alarm. Initially, it had a rather peaceful purpose - code gabbers were used in service services to unlock the car's alarm in case of its failure. But the criminal world has found a different purpose for this device.
Criminals, using code grabbers, intercept the signal code sent from the car owner's key fob when the car is armed. This code is remembered and used at the right time to enter the car.
VARIETIES OF CODGRABBERS
The most common code grabbers come in three forms:
The Dialogue protection scheme is considered the most reliable. The principle of its operation is that the signal sent from the car owner's key fob is received by the car alarm control unit. After receiving a signal, this unit checks whether there is in the memory the device that sent this signal (key fob). Then it sends back its request signal to the key fob. The keychain processes it according to a secret algorithm. The processing result is again sent to the signaling unit, where it is reconciled according to the same algorithm. Only after comparing the results by the control unit, the car is disarmed.
But the algorithmic code grabber successfully copes with such complexities. After intercepting the signal from the key fob, the manufacturer of the security system is determined. Next comes the comparison with the factory "secret" codes base, and the graber starts working in accordance with the received data. The factory database is formed due to information leaks from the manufacturers.
Safety alarm with auto start
From the above, a sad picture emerges that there is a code grabber for each alarm. This is partly true. If the alarm is electronic, then sooner or later there will be craftsmen who will crack it. Nevertheless, there is no need to give up. The creation of anti-theft systems and the discovery of ways to hack them has become a kind of sport. And this struggle between good and evil will never end. So there was an anti-code grabber for the code grabber, which can be purchased on the Internet for a certain amount, in fact, like the grabber itself.
Therefore, in order to protect your car, along with electronic security systems, it is advisable to use mechanical means of protection.
MECHANICAL MEANS OF PROTECTING THE VEHICLE AGAINST THEFT
Gearbox blocker
Modern mechanical anti-theft devices are blocking devices for transmissions, steering systems or pedals. Even if attackers manage to open the car using a code grabber, it will take at least additional time to remove the mechanical anti-theft protection. And if we take into account the fact that for the hijacker, seconds are counted, then it is quite possible that he will not waste his time hacking an additional mechanical system. In addition, manufacturers of mechanical anti-theft devices are constantly improving their devices, supplying them with their own secrets.
IMMOBILIZERS
Where is the standard immobilizer
Immobilizers are also one of the popular methods of protecting a car from a code grabber. The meaning of the immobilizer lies in its name. Translated from English, it is an immobilizer. It opens one of the electrical circuits supplying the starter, gasoline pump or ignition. The machine is locked or unlocked only with a special key or key fob. There are immobilizers that allow you to start the car unauthorizedly, and the blocking is activated only after a while along with the sound of the alarm. This is done in case the attacker does not have time to disarm the device.
Code grabbers are used not only by car thieves, but also simply by lovers of other people's goods. They don't need a car. Thieves are content with the things that the owner left in the car. The machine is opened, and after the appropriation of all values, it is closed again. Therefore, there is no need to leave valuables and documents in the car. Among other things, leaving the car unattended at the service station, it is better to take the alarm key fob with you, and put the security system into service mode. This is necessary to eliminate the temptation of unauthorized persons to add an extra key fob to the system. The number of key fobs tied to the security system must be kept under control.
All of the above means of protection and simply caution can protect the car from encroachments on it by intruders, regardless of which code grabber they use.

VARIETIES OF CODGRABBERS
The most common code grabbers come in three forms:
- Code grabber for signaling using static code (simple and cheap security systems).
- A code grabber that uses a substitution code when working. The device is equipped with a jammer, which suppresses the code sent from the "native" key fob, and replaces it with your own. Therefore, if the car did not arm itself from the first press of the button (the alarm did not turn on), but only triggered on subsequent pressings, there is a reason to be wary. Perhaps a grabber was triggered, which muffled and changed the signal.
- Algorithmic code grabber. The device is able to cope with even reliable alarms that use a dialogue scheme in their work.
The Dialogue protection scheme is considered the most reliable. The principle of its operation is that the signal sent from the car owner's key fob is received by the car alarm control unit.
