Car key programming is the process of syncing a replacement key's internal transponder chip with the automobile's On-Board Computer (ECU) or immobiliser unit. When a set key is placed into the ignition or brought within a keyless-start car, the car sends out an electronic signal to the key. The key then responds with an unique digital code.
