When You Need Car Key Replacement

You might need a replacement car key in several common situations:

Lost car keys or stolen car keys and no spare available
Broken or damaged car key (snapped blade, cracked fob, worn buttons)
Key stuck in ignition or door, or broken ignition key extraction required
Faulty car key fob, key fob not responding, or key not detected
Central locking not working because the remote has failed
Need a spare car key for convenience, resale value, or a new driver in the household

If your issue is specifically a lost or stolen set, see our guidance on lost or stolen car keys. If your key has physically broken, our team can also help with broken car key repair and replacement options.

How Our Car Key Replacement Service Works

We aim to make the process simple, quick, and non-destructive wherever possible.

Secure and Verify

We’ll confirm vehicle ownership and your ID for security.
We identify your vehicle’s make, model, year, and key type (basic, remote fob, smart/proximity).

Decode and Cut

Using dealer-level equipment, we obtain the correct key profile and cut a precise key blade. We carry laser-cut and high-security key machines for modern vehicles.

Program the New Key

We program the chip (transponder) so the immobiliser recognises it. This may be via OBD2 diagnostics or, for certain models, EEPROM/ECU programming.
For smart keys and proximity fobs, we complete smart key programming and remote central locking pairing.

Test and Hand Over

We test mechanical operation, remote locking, and engine start.
You get a working key, along with guidance on care and warranty details.

Wherever possible we use non-destructive entry methods. In rare cases—such as severe lock damage or certain high-security systems—minimal drilling or lock repair may be necessary. We always explain options before starting any work.

Key Types We Replace

Standard transponder keys (chip keys)
Remote keys and flip keys
Smart keys and proximity keys for push-to-start vehicles
High-security, laser-cut keys

Car key won’t turn in the ignition
Key fob stopped working or only works at very close range
Car displays key symbol or “key not detected” message
Worn out key blade that no longer operates the door or ignition
Remote buttons cracked or missing
Central locking not working on one or more doors

If your issue sounds like a remote fault rather than a lost key, see our help page for key fob not working.
