How Much Does a Spare Car Key Cost in the UK?
A spare car key costs less than the same key made in an emergency, because a planned spare is a copy job: the working key is cloned and the car accepts it with a short procedure. Price still varies by make, model, year and key type. For an exact figure, call or WhatsApp 07367 634032 with your registration.
A spare key is the cheapest insurance in motoring — but what does one actually cost? The honest answer is that it varies by make, model, year and key type, and that a planned spare costs noticeably less than the same key made in an emergency. This post is about the planned spare: cut while you still hold a working key, on your driveway, at a time that suits you.
If you are pricing an emergency instead — lost keys, no spare, car immobile — our guide to car key replacement costs in the UK covers that side in full. And if you need convincing that a spare is worth having at all, why you need a spare car key makes the case.

Why a planned spare costs less than an emergency key
With a working key in your hand, the locksmith clones rather than originates: the blade is copied, the chip data is read from the existing key, and the car accepts the newcomer with a short add-a-key procedure. No code retrieval, no full security routine, no urgency premium.
Compare that with losing every key: the blade must be cut to code from the manufacturer record, the car goes through a full all-keys-lost programming procedure, lost keys are erased from memory, and the callout is usually urgent — sometimes at night, sometimes far from home. Every one of those steps adds time and cost. The spare avoids all of them, which is why the cheapest key you will ever buy is the one you buy before you need it.
The four things that set the price of a spare
No reputable locksmith quotes a spare without knowing your car, because these four factors decide the job:
- Key type — a plain transponder blade is the simplest copy; a remote fob adds buttons and a remote circuit; a proximity (keyless) fob is the most involved, with the most expensive blank
- Make, model and year — some cars accept a new key in minutes, others need a longer programming routine or a dealer-level procedure
- Remote functions — if the spare must lock, unlock and start the car remotely, every function is tested, not just the blade
- Your situation — a scheduled daytime visit on your driveway is the cheapest setting; urgency always adds cost
Planned spare versus emergency replacement, side by side
The clearest way to see where the money goes is to put the two jobs next to each other. Same car, same key — very different work:
| Planned spare | Emergency / all-keys-lost | |
|---|---|---|
| Cutting | Copied from your working key | Cut to code from the manufacturer record |
| Programming | Short add-a-key procedure | Full security procedure; lost keys erased |
| Timing | Scheduled, daytime, at your convenience | Urgent — often evenings, weekends or roadside |
| Ownership check | Photo ID; simpler with a working key in hand | V5C plus photo ID, strictly verified |
| Relative cost | The lowest price for that key | The highest price for that key |
Dealer, locksmith, or the high-street cutter?
Three routes exist for a spare, and they are not interchangeable. A high-street cutter can duplicate a simple metal blade, but it cannot program a transponder chip — so for most cars built this century, the copy will turn the locks and then fail to start the engine. Fine for a house key; not a car key.
A franchised dealer can do the whole job, usually at the highest price and on their timescale, with the car brought to them. A mobile auto locksmith sits between the two: full cutting and programming, done on your driveway, typically well below dealer pricing and often the same week you call. For a planned spare — no emergency, no towing — the locksmith is the natural choice for most drivers.
How to get an accurate quote for a spare
A proper quote takes one message. Send the locksmith the details below on a call or WhatsApp, and the figure you get back will be a real one — clear, before any work starts, with no obligation:
- Registration number, plus the exact make, model and year
- A description or photo of the key — blade only, remote buttons, or keyless fob
- Whether you want one spare or one for each driver
- Your location and a rough idea of when suits you
What about a spare for a keyless or proximity car?
Keyless cars are not excluded from the spare logic — they just need the right fob and the right pairing procedure. A proximity spare is programmed to the car in the same planned visit, and every function is tested: keyless entry, push-button start, remote locking and the boot release.
The blank costs more than a simple blade, which is why a proximity spare sits at the top of the spare price range — but the planned-versus-emergency gap is widest here too, because an all-keys-lost job on a keyless system is among the most involved work there is. If your car never takes a physical key, the spare matters even more: there is no metal blade to fall back on at all.

Frequently asked questions
Is it cheaper to get a spare key before I lose the original?
Yes. A planned spare is a copy job, while an all-keys-lost key has to be originated from code with a full programming procedure. The spare is the cheapest key you will ever buy.
Can any car key be duplicated as a spare?
Most can. Simple blades are straightforward, while remote and proximity fobs need the correct blank and programming. Your registration lets the locksmith confirm before booking.
Do I need the V5C logbook for a spare key?
Proof of ownership is still checked, though the process is simpler when you hold a working key. Have photo ID ready, and the V5C too if it is to hand.
How long does cutting a spare key take?
Often a single short visit once the correct blank is confirmed. More complex fobs can take longer, and we will say so honestly when you ring.
Should each driver in the house have a spare?
It is sensible. A shared car with a single key is exactly how lockouts and lost-key emergencies start, and those cost far more than a spare.
