What is Car Key Programming?
Car key programming is the process of syncing a replacement key's internal transponder chip or electronic fob with the car's On-Board Diagnostics (OBD) system or Engine Control Unit (ECU). Without this synchronization, the car's immobilizer-- a security device that prevents the engine from running unless the right key is present-- will not allow the lorry to start.
When a digital key is placed into the ignition or brought within distance of a push-to-start lorry, the car sends a signal to the key. The key must react with a distinct digital "handshake." If the codes do not match, the car remains a fixed hunk of metal.
