What We Programme

Six core programming services, all done at your car, all same day.

Transponder chip programming

The most common form. We write the immobiliser code into the chip inside your key so the car will start. Applies to virtually every car made after 1998 with a plastic-head key.

Remote / fob programming

Pairing the buttons (lock, unlock, boot) to the car. Different from the transponder — the immobiliser and the remote are two separate systems that both need to be synced.

Proximity / smart key programming

For push-to-start cars. The key is identified by radio when it's near the car, and the engine starts with a button. Modern cars with this system (BMW, VW, Mercedes, Audi) need online component protection authorisation.

Component protection authorisation

For German cars especially — VW, Audi, BMW, Mercedes. The new key has to be authorised online against the manufacturer's server before the car will accept it. We carry the access needed to do this at your car.

Key deletion

Removing a lost or stolen key from the car's memory. The key's transponder code is wiped from the immobiliser, so the lost key can no longer start the engine even if someone finds it.

Key cloning

For some older cars, we can clone the existing key's transponder so the new key works without needing a direct connection to the car. Useful as a backup, but the cloned key can never be deleted from the car.

Frequently Asked Questions

Replacement is the full job — a new blank key is cut to your lock and the transponder chip is programmed to match your car's immobiliser. Programming alone is when you already have a key (often a new aftermarket fob, or a second-hand key from eBay) and you just need the electronics paired to the car. Programming is quicker and cheaper because there's no cutting involved.
