Need emergency car key programming?
Modern cars are complicated. You cannot just cut a key and stick it in the ignition anymore. The key has a chip. That chip needs programming to talk to your car’s computer. Without proper programming, the key is just a useless piece of plastic and metal.

What Car Key Programming Actually Means
Modern vehicle keys contain transponder chips or remote fobs. These communicate with your car’s immobilizer system. The immobilizer stops the engine starting unless it recognizes an authorized key.
Programming means teaching your car’s computer to recognize a new key. This service is available across Forest Hill, ,and Redhill.
We connect diagnostic equipment to your vehicle, access the immobilizer system, add the new key to the database of authorized keys, and test it works properly. Job done.

Louis Reeves
Bought a spare key online for my Ford but could not get it programmed anywhere. Dealer wanted ridiculous money. These guys came to my house in Ealing, programmed it in 40 minutes for under a hundred quid. Works perfectly. Saved me a fortune.

Amanda warner
My Audi key fob stopped working after I changed the battery. Thought I broke it. They explained it just needed reprogramming. Came to my office in Canary Wharf, sorted it in 15 minutes. Cannot believe how simple it was.

Kevin Durbin
Lost all my Volkswagen keys. Dealer said a week wait and over three hundred pounds. Found these lot online. They came same day, programmed two new keys at my home in Clapham for under two hundred total. Professional service, fair price.
