Car Key Replacement — Cut & Programmed at Your Vehicle
Replacement car keys are the core of what we do. A modern car key is two things at once: a mechanical part that operates the door and ignition, and an electronic part that the vehicle has to recognise before it will start.
That is why a key cut from a photograph or bought unprogrammed online frequently disappoints. The metal may fit the lock perfectly while the immobiliser refuses to accept it. Both halves of the job matter, and we handle both at the vehicle.
The types of key we replace
Knowing which type you have helps us quote accurately, and it is usually obvious from looking at the key you already hold — or from how you used to start the car.
- Remote key: a bladed key with lock/unlock buttons in the head
- Flip key: a blade that folds into the fob body
- Keyless / proximity key: no blade used day to day, the car starts on a button with the fob in the cabin
- Basic transponder key: no buttons, but a chip inside that the immobiliser reads
- Emergency blade keys hidden inside a keyless fob
Main dealer or auto locksmith?
A main dealer route generally means recovering the vehicle to them, ordering a key against the vehicle's records and waiting. That is sometimes the right answer, particularly on very new vehicles or where a specific dealer-only procedure applies.
For a large proportion of everyday vehicles, a mobile auto locksmith is quicker and less disruptive, because the work happens where the car already is. We will say plainly if we believe your vehicle is a main dealer job rather than taking on work we cannot finish.
How a replacement key job usually runs
We confirm the vehicle details and key type by phone, arrange a time, and attend the vehicle. On site the mechanical key is cut to the vehicle's lock, then the electronic side is programmed so the immobiliser accepts it. We test the doors, the boot, the remote buttons and the start function before leaving, and hand over a key that works exactly like an original should.
What affects the price
There is no single price for a car key, and any business quoting one before knowing the vehicle is guessing. The main factors are the type of key the vehicle uses, whether you still hold a working key, the make and model, and how the vehicle's security system is designed. We quote against your actual vehicle before attending.
Frequently asked questions
- Can you replace a keyless (push-button start) key?
- On many vehicles, yes. Proximity keys are more involved than a basic remote key and support varies by manufacturer and model year, so we confirm against your specific vehicle first.
- I bought a key online — can you just programme it?
- Sometimes. Aftermarket fobs vary greatly in quality and some cannot be programmed reliably. We are happy to look at one, but we cannot promise in advance that a key we did not supply will work.
- Will a replacement key work the boot and the alarm too?
- A correctly supplied and programmed key should operate the same functions as the original, and we test the buttons and start function before we leave.
- Do you cover vans as well as cars?
- Yes — van keys are a significant part of our work, and losing a work van key is usually more urgent than a car key.
