Peugeot Key Programming - Replacement
All Peugeot models, from 1998 upwards, have been built with a factory installed immobiliser system. It is coded with a serial number that matches one coded on a microchip embedded in the car key. It’s impossible to start your car without the correct key.
Some early Peugeot models use a separate immobiliser box that “talks” to the car’s electric control unit (ECU). Some of the later models use an immobiliser system that is combined with the ECU and dashboard clocks.
