The Main Price Factors
The number on your quote moves with these factors:
- Key type — a plain blade key is the cheapest job; a transponder chip key, a remote fob or a smart key each add parts and programming time.
- Make, model and year — some cars need dealer-level codes or longer programming sessions.
- All keys lost vs a spare — starting from code and programming from scratch is more work than copying a key you still hold.
- Time of day — a callout in the night costs more than the same job booked in daytime.
- Your location — the quote covers our travel to you as well as the key work.
Key Types Explained
Basic blade keys: cut metal, no electronics, found on older cars — the quickest and cheapest to replace.
Transponder keys: a blade with a chip inside that the car immobiliser must recognise. No pairing, no start.
Remote fobs and flip keys: a chip plus buttons for remote locking, both synced to the car.
Smart keys: keyless entry with push-button start — the most involved, and the most expensive, to replace.
Locksmith or Dealer?
A mobile auto locksmith reaches your location and usually needs no towing; the quote comes before anything starts. A dealer needs the car brought to them, usually needs a booking, and the car may have to be recovered there first. Either route ends with a working key — the difference is convenience and process, so compare like with like.
Documents You Will Need
Expect to show photo ID and proof of ownership, like the V5C logbook, before anyone cuts you a key. It is a security check that protects you — steer clear of anyone who will cut a key with no questions asked.
