Peugeot Keys Information - Remotes, Immobilisers & Transponders

From approx. 1995 Peugeot began to use a transponder chip, for the immobiliser, system within their key fobs. Although not right across the whole range. If your Peugeot vehicle has an immobiliser keypad installed then it does not use the transponder chip system.

What is a transponder chip?

The transponder chip contains a code which corresponds with the ignition system in the vehicle. Without it the vehicle will not start. Eventhough the engine may turn, it will not fire up.

The system works basically as follows: Once you insert your key into the ignition and turn, the ECU (your vehicle's computer) interrogates the transponder chip within your keyfob. If it transmits the correct code the ECU will allow the vehicle to start, otherwise the vehicle will remain immobilised.

Security Card?

Every new Peugeot vehicle using this system is supplied with a security code card (credit card sized) in case you should need new keys. The code itself cannot be used to program new keys but allows access to the vehicle's immobiliser system so new keys can be programmed to it.
Programming the transponder chip requires specialist equipment.
