Anti-theft switches or immobilizers are one of the newest and most efficient car security systems that have been common among cars in the world since 2000 and became mandatory for Iranian cars since 2006. The basis of this system is that due to the software lock that is installed on the ECU, the car can only use its own switch that contains an electronic chip that is already introduced and programmed to the ECU and immobilizer system of the car. It is turned on. If other switches are used, due to the immobilizer system not recognizing the switch, the car will not turn on even if it is started.
The chip embedded in the plastic handle of the switch is a type of electronic memory that contains Access code is exclusive to Yemen. When the key is inserted into the car switch, the chip communicates wirelessly with the antenna around the switch and announces its access code to the immobilizer system, and if the code is confirmed, the command to turn on the car is issued to the ECU. This process is done in only a fraction of a second and the user does not feel any delay in turning on his car. Such as breaking, breaking or losing your switch, needing an extra spare key, etc., needing to make another switch. Or it may be that the security of the car is compromised due to the loss of the switch and it is necessary to change the car code to prevent possible misuse by other persons with the lost switch.
