Quick answer
Bought a blank key online? Got a second-hand fob that needs pairing? Key programming is the step that makes a piece of plastic actually work with your car — the immobiliser has to learn the key's identity before the engine will start. We do it at the roadside with proper diagnostic equipment.
We program transponder keys, remote fobs and proximity/smart keys through your car's OBD port, anywhere in Birmingham, 24/7. Call 07425 435697 — tell us the car and the key, and we'll quote on the phone before we set off.
How it usually happens
- New key needs coding to the car
- Second-hand key to be programmed
- Fob desynchronised

What happens during programming
We connect specialist diagnostic equipment to your car's OBD port and communicate with the immobiliser and body control modules. The new key's transponder or fob identity is registered in the car's memory — the handshake the car performs every time you start it. We then test thoroughly: remote lock and unlock, blade in the door, and engine start, several times. If the immobiliser light misbehaves, we don't leave until it's right.
Keys bought online: the honest truth
Some online blanks program fine; others are the wrong frequency, a cheap clone chip the car rejects, or for a different region's model. We're happy to try programming a key you supply, but we can't guarantee a key we didn't source — and if it won't take, you'll still have paid for the programming time. If you want certainty, let us supply the key: then it's our problem, not yours.
What it costs
It depends on the car — anyone quoting one flat price without asking the make and model is guessing. We confirm the exact figure on the phone before we set off.
- Make and year — some need dealer-level access
- Whether a working key exists
- Number of keys to program
Car Key Programming — questions we get asked
I bought a key online — can you program it to my car?
Often, yes — if it's the correct key for your exact make, model and year. But we can't guarantee third-party keys: wrong frequency or cheap clone chips get rejected by the immobiliser. If you'd rather not gamble, we can supply a guaranteed key ourselves.
How long does key programming take?
It depends on the car — some take minutes, others need a longer session with security access. We'll give you a realistic idea on the phone once we know the make, model and year. Either way, it's done at your car in one visit.
Will programming a new key affect my existing keys?
No — your existing keys keep working as normal. In fact, if you've lost a key, we can erase the missing one from the car's memory during the same session so it can never start the car again. Just ask.
My dashboard shows a key or immobiliser warning light — can you fix that?
That light usually means the car isn't recognising the key — a failed chip, a lost pairing, or an immobiliser aerial fault. We diagnose it with proper equipment rather than guessing, then fix the actual cause.
Do you need the car, or can you program from just the key?
We need the car — programming happens through the OBD port, talking to the car's own modules. Anyone offering to program a key without the vehicle present isn't doing the job properly.
