Lost Car Keys in London
Lost all your car keys or had them stolen? CarKeyPro provides mobile lost car key replacement across London and surrounding areas for supported vehicles, including situations where no working spare remains.
Send us your registration number, model year and postcode, and confirm that you have no working key. We will check the replacement options and availability before arranging your appointment.

Can You Replace Car Keys Without the Original?
For many supported vehicles, yes. We can supply replacement car keys without a working original, cut the required blade and complete car key programming where needed. The procedure depends on the make, model, year and fitted security system.
If your vehicle is locked, let us know when you contact us so we can plan how to gain access. We will check your vehicle details and confirm the available key replacement options before arranging the appointment.
How Our Lost Car Key Service Works
Send your vehicle details
Share the registration, make, model, year and postcode. Tell us whether the keys are lost or stolen and whether the vehicle is locked.
We check the available options
We confirm whether we can support the vehicle, explain the proposed work and provide a quote or estimate. Appointment availability is discussed at this stage.
Prepare for the visit
Have photo ID and proof of ownership or authority ready. Tell us about parking restrictions or anything that could affect access to the vehicle.
Replace and test
We carry out the agreed work, including key cutting and programming where required, and test the relevant starting, remote-locking and mechanical-key functions.
Mobile Lost Car Key Assistance Across London
For suitable vehicles and procedures, we can work at your home, workplace or another accessible location. Mobile replacement can avoid the need to transport the vehicle to a dealership.
Support depends on the vehicle and its security system. Please send us your vehicle details so we can check.
Lost or Stolen Keys: Securing Your Vehicle
Where the vehicle supports it, a missing key can be removed or invalidated from the authorised electronic key memory. The available options depend on the fitted system.
This does not change the physical door lock. A missing mechanical blade may still unlock it, so tell us if the key was stolen and you are concerned about access.
How Much Does Lost Car Key Replacement Cost?
The cost depends on the vehicle, key type, access requirements and programming procedure. Having no working key can involve more work than adding a spare.
Send us the vehicle details and postcode for a quote. We explain what the proposed price covers and discuss any additional work identified before proceeding.
Documents Needed
Please have photo ID and proof of vehicle ownership or authority available for inspection. If you are arranging the work for someone else, tell us in advance so we can confirm what is needed. We inspect these documents and do not retain copies.
Lost Car Keys FAQ
Can you attend today?
Contact us to check availability. The earliest appointment depends on your location, the vehicle, key availability and the work required. We confirm timing before booking.
Will my car need to be recovered?
Often, suitable jobs can be completed at the vehicle. Some vehicles or faults need a different approach, so we check the details before advising you.
What if my keys are locked inside the car?
You may only need vehicle lockout assistance. Tell us where the keys are and whether a working key will be available once access is restored.
What if I still have one working key?
You can usually request a spare car key instead. Tell us that a working key remains so we can check the appropriate additional-key option.
