Yes — this is called an all-keys-lost job. Even with no working keys at all, I can create a new key from your vehicle’s IMMO data or VIN using the Dealer-grade OBD equipment. The key is cut on-site and programmed to your vehicle. Once complete, all previous key codes are deleted from the ECU — so even if the original keys are found later, they can no longer start the car. This is a more involved process than adding a spare, and pricing reflects that.

Key programming (also called key coding or transponder programming) links a key’s electronic chip to your vehicle’s immobiliser system. Without programming, a key will fit the lock but will not start the engine. Every modern car key — including proximity, flip-key, push-start and standard blade keys — requires programming. Cutting alone is never sufficient. See our car key programming page for make-specific details.

Yes, and this is significantly quicker and cheaper than an all-keys-lost scenario. If you have a working key, I can programme an additional spare in one visit — typically 30–45 minutes. I’d strongly recommend getting a spare before you need one: a spare key made proactively costs far less than an emergency replacement after losing all keys.

Most key fob failures are battery-related, but not all. I diagnose the fault on-site: it could be a depleted battery, a cracked PCB, a failed antenna, or lost programming caused by a low vehicle battery. In most cases I can repair or replace the fob and reprogram it on-site. If the internal circuit has failed beyond repair, I supply a new housing with the correct chip and recode it to your vehicle.

Yes — I cover proximity entry and push-button start programming for most makes and models via Specialist OBD equipment, VAG Group specialist programmer, BMW Group OBD equipment and Dealer-grade OBD equipment. A small number of the newest high-security systems (certain post-2021 vehicles) require manufacturer-level access that no independent locksmith currently has. I’ll always confirm whether your specific vehicle is within scope before I travel. See the car key programming page for details.

Key cutting produces the physical blade profile that fits your door lock and ignition barrel. Key programming links the electronic transponder chip inside the key to your vehicle’s immobiliser, allowing the engine to start. A working replacement key requires both. Some locksmiths cut keys without programming — the result opens your doors but the engine immobilises when you try to start.
