What is the Chip in a Car?

[DeLeonardo]

Car chips are electronic devices that control the safe operation of a vehicle. Below is relevant information about car chips: Location of the car chip: The car chip is located inside the tail of the car key. When the car key is turned in the ignition switch, the engine control unit (ECU) in the car sends an encrypted electronic code signal to the chip inside the car key. The vehicle will only start if the car ECU unit can read and receive the correct anti-theft code signal. Classification of car keys: Car keys are divided into two types: one without an anti-theft chip and another with an anti-theft chip. Keys with anti-theft chips are naturally more advanced. Besides the mechanical key part needing to be correct, the key must also be reprogrammed so that the code of the key chip matches the code of the engine anti-theft system completely to start the engine.
