Car key programming is the process of syncing a replacement key's internal transponder chip with the car's On-Board Computer (ECU) or immobiliser system.

The key then reacts with a distinct digital code. If the codes match, the immobiliser is shut off, and the engine is permitted to begin.

Without this digital "handshake," the car will not start, even if the metal blade of the key completely matches the mechanical lock.

3. EEPROM/Soldering
For high-security vehicles or when all secrets are lost, the professional might require to eliminate an electronic module from the car, such as the immobiliser or the ECU.
