Spare Car Keys in London
Only have one working car key? Arrange a spare before you need it. CarKeyPro supplies, cuts and programs additional car keys and fobs across London and surrounding areas, with a mobile service for supported vehicles.
Send your registration number, model and year, and postcode. Tell us whether your current key starts the vehicle so we can check compatibility and provide a quote.
Why Have a Spare Car Key?
A second key is useful if you share the car, bought it with only one key or want a backup if the original goes missing. Arranging a spare while a key still works can be simpler than replacing all keys after a loss.
Keep the spare separate from your everyday key and check it occasionally, so it is ready when you need it.
Spare Keys, Remotes and Smart Fobs
Depending on your vehicle, the available options may include:
- Transponder keys with a chip recognised by the vehicle's immobiliser.
- Remote and flip keys with buttons for locking and unlocking.
- Smart or proximity fobs for compatible keyless-entry and push-button-start systems.
We check the suitable key type and blade requirements for your model and year. If you prefer a genuine manufacturer key, mention this when enquiring so we can check availability.
How Our Spare Key Service Works

Share the registration, model and year, postcode and number of working keys.
A photograph of the existing key can help.

Cut, program and test
We complete the agreed key cutting and car key programming, then check the relevant starting, remote-locking and blade functions, along with the keys being retained.
Mobile Spare Key Service
For suitable vehicles, we can make the spare at your home, workplace or another accessible location across London and surrounding areas. Send your postcode so we can confirm coverage and availability.
Compatibility varies depending on the vehicle and the security system it uses. Please send us your vehicle details so we can check.
How Much Does a Spare Car Key Cost?
The price depends on the vehicle, key type, parts and programming required. A basic transponder key and a smart fob can involve different work. We explain which key is being supplied and what the quote or estimate includes before you agree to proceed.
New keys and remotes we supply and program carry a 12-month warranty against product defects and workmanship faults. See our Terms & Conditions for the scope and exclusions.
Spare Car Keys FAQ
Do you need the vehicle and my existing key?
Usually, yes. We generally need the vehicle for programming and function checks. Have all available keys ready, as some procedures require the keys you want to keep using to be present.
Will my original key still work?
The aim is to add a working spare while keeping the existing key in use. We check the required procedure and test the keys being retained before completing the job.
Can you use a key I bought online?
Sometimes, if it is compatible and suitable for programming. Please check with us before buying: matching the appearance alone is not enough, and a used key may not be reusable.
How long does it take to make a spare?
Timing depends on the vehicle, programming procedure and key availability. We discuss the likely appointment length and any parts that need ordering after checking your details.
What if I no longer have a working key?
Tell us when you enquire, as the work can differ from adding a spare. Use our lost car keys service if no key remains, or our replacement car key service for a damaged or faulty key.
