What is Car Key Programming?
Car key programming is the process of syncing a replacement key's internal Transponder Key Programming chip with the lorry's On-Board Computer (ECU) or immobiliser system. When a set 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 responds with a distinct digital code.

Without this digital "handshake," the car will not start, even if the metal blade of the key completely matches the mechanical lock.
Common Reasons for Programming a New Key
