Key Types

Key types we program

Car key technology varies by make, model, and year. We carry equipment for all of the following.

Transponder keys

A chip inside the key communicates with your car’s immobiliser. If the chip isn’t coded correctly, the car won’t start. We program transponder keys for all major makes and models.

Remote key fobs

Fobs with buttons for central locking and boot release need to be synced to your car’s receiver. We program both OEM and aftermarket fobs on-site.

Smart keys and keyless entry

Proximity keys that allow hands-free entry and push-button start. These require specialist equipment to program — we carry it as standard.

Flip keys and combination keys

Keys with a folding blade and built-in remote. Both the blade and the electronics need to be matched to your vehicle.

FAQs

Car key programming FAQs

Can you program a car key if I’ve lost all my originals?

Yes. We can program a completely new key to your vehicle with no original present. This applies to transponder keys, remote fobs, and smart keys across all major makes and models.

How long does car key programming take?

Most programming jobs are completed in 30 to 60 minutes on-site. We’ll give you a realistic estimate when you call.

Is car key programming cheaper than the dealer?

Yes, and considerably more convenient. There’s no appointment to book, no recovery truck needed, and we come to you wherever you are in Kent.

Can you program keys for any make and model?

We cover the vast majority of makes and models on UK roads, including Ford, Vauxhall, BMW, Mercedes, Audi, Volkswagen, Toyota, Nissan, and more. Call us to confirm for your specific vehicle.

What’s the difference between car key cutting and programming?

Cutting shapes the physical blade of the key so it operates the lock. Programming codes the electronic chip to the car’s immobiliser so the engine will start. Both are needed for a fully functional replacement key, and we do both on-site.

Can you fix a key that’s stopped working?

Often, yes. Keys can lose their programming through low batteries, proximity to other electronics, or faults in the car’s receiver. We diagnose the issue on-site and reprogram or replace the key as needed.

Do you program keys for electric vehicles?

Yes. We program keys for most electric vehicles, including popular models from Nissan, Renault, Tesla, and Volkswagen. Call us to confirm compatibility for your specific EV.

Do I need to be present with the vehicle?

Yes. For security reasons we require the registered keeper or an authorised person to be with the vehicle, with proof of ownership or ID.
