Car anti-theft system refers to a system designed to prevent theft of the car itself or the items on the car. It consists of an electronically controlled remote control or key, electronic control circuitry, alarms and actuators.
Engine electronic anti-theft introductionEngine electronic theft is a set of anti-theft systems for engine installations, commonly referred to as an anti-theft lock system. For a car that has an anti-theft lock system, even a car thief can open the car and cannot drive the car.
Engine electronic anti-theft system; an anti-theft converter is embedded in each of your keys. When you insert the key into the ignition switch cylinder and rotate it to the "ON" position, the electronic anti-theft ECU and the key pass the radio frequency. The mode is communicated; if the key is confirmed to be legal, the immobilizer ECU will perform password verification with the engine ECU; if the password is verified correctly, the engine will be allowed to start.
The car ignition key contains electronic chips, each of which has a fixed ID (equivalent to the identification number). Only when the ID of the key chip matches the ID on the engine side, the car can start. On the contrary, if they are inconsistent, The car will automatically cut off the circuit immediately, making the engine unable to start. Unauthorized changes or modifications may void the operation of the immobilizer system. Unauthorized changes or modifications may void the operation of the immobilizer system.
Engine electronic anti-theft operation methodThe engine electronic anti-theft system warning light operates as follows: When the key is inserted into the ignition lock cylinder and rotated to the "ON" position. If the password verification is successful, the warning light is off and the engine is allowed to start: if the password verification fails, the warning light will remain on for 2 seconds. The frequency is blinking: When the vehicle is in the unattended state, the electronic anti-theft system is at In sleep mode, the warning light will flash for 5 seconds.
(1) When you insert the key into the ignition lock cylinder and turn it to the "ON" position, do not place objects with strong magnetic fields near the ignition lock cylinder.
(2) Do not place the key in a special high temperature or low temperature environment.
(3) Do not drop the key on the ground.
(4) Do not squeeze the key with heavy objects.
When you are unable to start the engine, please turn the key to the "ACC" position and then turn it to the "ON" position. Please check:
1. Is your key a legal key?
2. Whether the engine electronic anti-theft system warning light flashes at a frequency of 1 second lighting. Also check if the engine service indicator flashes at a certain frequency. If the above phenomenon occurs, it is likely that the engine electronic anti-theft system has failed. Please contact the car special service station to repair the engine electronic anti-theft system.
3. The anti-theft converter inside the key is intact.

The so-called engine electronic anti-theft is actually the engine electronic anti-theft system, which has an anti-theft converter embedded in each of your keys. When you insert the key into the ignition lock cylinder and rotate it to the "ON" position, the electronic anti-theft ECU communicates with the key via radio frequency. If the key is confirmed to be legal, the immobilizer ECU will perform password verification with the engine ECU. If the password is verified correctly, the engine will be allowed to start. Is the engine electronic anti-theft useful?
The main function of the engine electronic anti-theft system is to see if the communication between the electronic anti-theft ECU and the key is correct by means of wireless radio frequency, and the right to start the engine is obtained. The anti-theft of the engine is to build a chip inside the key, which preserves the uniqueness of the car. An ID that matches the frequency signal ID in the engine and the key chip at startup. In this way, the general imitation key can not start the vehicle, improving the safety performance.
However, the electronic anti-theft of the engine is not 100% safe, especially for the luxury brands. Some theft gangs use special instruments to copy the keys with identification chips. So there are some people who will install a dark lock. There is also a PIN code security envelope for the engine electronic anti-theft system in the user manual of the vehicle. The secret envelope contains the PIN code of the engine electronic anti-theft system. If the PIN code of the anti-theft system is stolen by other personnel, the anti-theft system may be cracked by unscrupulous personnel. Therefore, it is recommended that the owner of the car to install the engine electronic anti-theft system is best to buy the best.
1, can be installed engine electronic anti-theft, directly to the 4S shop to install.
2, the role: electronic anti-theft, that is, the central control key needs to be detected with the chip in the key socket, the engine can be launched.
