What is Car Key Programming?
Car key programming is the process of syncing a replacement key's internal transponder chip with the vehicle's On-Board Computer (ECU) or immobiliser system. When a configured key is placed into the ignition or brought inside a keyless-start lorry, the car sends out an electronic signal to the key. The key then reacts with an unique digital code. If the codes match, the immobiliser is shut down, and the engine is enabled to begin.

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