When You Need Help With Lost Or Stolen Car Keys

If any of the following sound familiar, our mobile auto locksmith service can help on your driveway, at work, or roadside:

• Lost car keys at home, work, the gym, or on public transport
• Stolen car keys after a bag, jacket, or wallet theft
• Locked out of your car with no spare key available
• Moving house or buying a used car and want old keys disabled
• Key fob not responding after loss and recovery (or suspected cloning risk)
• You’ve found the key later, but want to erase it from the vehicle memory for peace of mind

Related issues we can handle at the same visit:

• Non-destructive vehicle unlocking to retrieve any belongings
• Immediate car key replacement and car key programming
• ECU/immobiliser programming to delete missing keys from the system
• Remote central locking repair if the fob has stopped working
• Ignition repair and replacement if a damaged barrel prevents starting

If your keys were stolen, we strongly recommend immobiliser reprogramming and, in some cases, changing door locks for security. We’ll advise you based on your vehicle and circumstances.

How We Secure Your Vehicle And Provide New Keys

We follow a proven, transparent process designed to protect your car and get you moving again as quickly as possible.

1. Identity and Ownership Check

• For your security, we’ll confirm photo ID and proof of ownership (V5C/logbook, insurance document, or another acceptable proof). If these are locked in the vehicle, we’ll work with you to verify details safely.

2. Non-Destructive Vehicle Entry

• Wherever possible, we use specialist lockpicks and air wedges to unlock your car without damage. For very few models or rare scenarios, minimal drilling may be required, but we will explain any exceptions clearly before work begins.

3. Key Cutting And Programming On Site

• We can create new keys without the original using manufacturer key codes, key decoding tools, or by reading vehicle data via OBD2.
• For many vehicles, we carry out OBD2 key programming. On some advanced systems (e.g., certain VAG, BMW, Mercedes, Jaguar/Land Rover, and newer models), we may perform EEPROM key programming or ECU/immobiliser programming to correctly pair the key and maintain factory-level security.

4. Deleting Lost Or Stolen Keys From Memory

• To secure your vehicle, we erase missing keys from the immobiliser so they no longer start the car. This is essential if keys are stolen or unaccounted for.

5. Optional Lock Changes And Security Advice

• If theft is suspected, we can replace door locks or steering lock components where appropriate. We’ll also advise on practical steps such as parking location, additional deterrents, and how to inform your insurer.

6. Testing And Handover

• We test remote locking, central locking, and engine start. We provide guidance on using your new key/fob, warranty details, and aftercare. You’ll leave confident that old keys can’t be used.

Tools and training we use:

• Dealer-level diagnostics, OBD2 interfaces, EEPROM readers/writers, laser key cutting for high-security blades, transponder chip programming, and brand-specific software. Our vans carry stock for popular models to speed up same-day solutions.

Helpful Guidance If Your Keys Are Lost Or Stolen

• If you think keys were stolen:

  • Move the vehicle to a visible, well-lit area if safe to do so.
  • Consider using a steering wheel lock until we arrive.
  • Inform your insurer and, if needed, obtain a crime reference number.

• If you can’t find your key but have a spare:

  • We can still delete the missing key from the system to prevent future misuse.

• Keep a photo of your registration and VIN (not publicly shared) for verification and faster processing when calling us.

• If your key was recovered later:

  • If we’ve already erased it from the car, it will no longer start the vehicle. We can reprogramme it if required after confirming security.

FAQs About Lost Or Stolen Car Keys

Can a locksmith make a car key without the original?

Yes. We can create a new key from your vehicle’s data using diagnostics, key codes, and specialist tools. We then programme the transponder or smart key so it starts the car, and we erase any missing keys for security.

How do I get a new car key without the original in South West London?

Call us with your location, vehicle details (make, model, year, registration), and proof of ownership. We’ll come to you, unlock the car if needed, cut and programme a new key, and secure the immobiliser.

Will you damage my car while unlocking it?

We use non-destructive entry methods wherever possible. For a small number of models or situations, minor drilling may be needed; we will explain this first and proceed only with your permission.

How long does it take to get a new key?

Many replacements are completed during a single mobile visit. The time varies by vehicle make/model, key type (remote/smart), and security system. We aim to provide same-day service across South West London subject to availability and parts.

Do I need to go to the dealer for key programming?

In most cases no. Our mobile technicians use dealer-level diagnostics, OBD2, and EEPROM techniques where required. We’re often faster and more convenient than a dealership, especially when you’ve lost every key.

Does car insurance cover lost keys in the UK?

Some policies include key cover or offer it as an add-on. Check your policy documents or ask your insurer. If you have key cover, we can provide an invoice for your claim.

Can you delete the lost or stolen key so it won’t start my car?

Yes. We erase missing keys from the immobiliser memory as part of our security process after loss or theft, so they can’t be used to start the vehicle.

What if my key was stolen along with my address?

Call us immediately. We’ll prioritise immobiliser reprogramming and discuss lock changes to ensure the vehicle cannot be taken using the stolen key.
