What is Car Key Programming?
When a driver inserts a key into the ignition or enters a vehicle with a clever fob, an intricate digital "handshake" happens.

If the codes do not match, the fuel system and ignition remain handicapped, preventing the lorry from being taken via conventional "hotwiring" techniques.
