- If theft is suspected, report it and obtain a crime reference number
- If the vehicle is still where the keys might be found by others, consider keeping it in sight until we arrive

Our Secure, Non-Destructive Solution
We focus on quick access, proper security, and a permanent fix. Our process is designed to be non-destructive wherever possible and to protect your vehicle against unauthorised use.
-
Identity and vehicle check
For your security and ours, we verify proof of ownership (e.g., V5C or other documents) and your ID. -
Non-destructive vehicle entry
If you’re locked out, we use specialist lock-picking tools and techniques to open the vehicle without damage wherever possible. On rare occasions where drilling or component removal is unavoidable (e.g., severely damaged locks), we explain the risks and costs before any work starts. -
Decode and cut new keys
We retrieve cutting codes using secure sources, dealer-level software, or lock decoding. We then cut replacement keys on-site (including laser cut and high-security profiles) to match your vehicle. -
Car key programming and immobiliser security
We programme transponders and remotes using OBD2 diagnostics. For certain models and anti-theft systems, we may use EEPROM or ECU/immobiliser programming to add new keys, remove lost or stolen keys from the system, and re-synchronise remote central locking. This ensures the missing key no longer starts the car or opens it remotely. -
Smart and proximity keys
For keyless and push-to-start systems, we can supply and programme new proximity keys, then block or delete the stolen key from your vehicle’s memory. We also address keyless entry programming and re-synchronisation. -
Testing and handover
We verify that the doors lock/unlock correctly, the engine starts reliably, and any stolen keys are erased from the immobiliser memory. You’ll receive a clear invoice and a warranty on workmanship and supplied keys/fobs. -
Optional mechanical lock changes
If there’s a high risk that a thief knows where your car is, or your locks are physically compromised, we can discuss lock barrel replacement or rekeying. In many modern vehicles, immobiliser reprogramming alone is sufficient, but we’ll give you straightforward advice for your exact make and model.
If you’re unsure which option you need, we’ll explain everything clearly and provide an upfront, no-obligation quote before we proceed.

Lost Or Stolen Keys: Common Scenarios We Fix
-
Lost only key and the car won’t open or start
We provide a complete solution: non-destructive entry, cutting a new key, and full transponder/remote programming so you’re back on the road securely. -
Stolen key with security concerns
We delete the missing key from your vehicle’s memory, add and programme new keys, and re-synchronise central locking so the old key can’t start or open the car. -
Keyless entry theft risk
We can adjust your vehicle’s key count, disable and remove lost proximity keys, and reprogramme new smart keys to reduce risk. -
Fleet and commercial vehicles
From vans to light commercial vehicles, we provide rapid, mobile support to keep your business moving.
If your situation involves a faulty fob rather than a lost one, our diagnostics can quickly tell the difference between a programming issue and a hardware fault. We also provide full car key programming if your immobiliser or remote needs a reset.
How We Protect Your Car’s Security
Modern vehicles rely on immobiliser systems that use a transponder chip in the key or fob. When we programme a new key:
- We add the new transponder into the immobiliser
- We remove missing keys from memory (so they can’t start the engine)
- We re-pair or re-synchronise the remote central locking
- We confirm the security light/key symbol clears on the dash, where applicable
On some models, especially higher-security or newer vehicles, we may need to perform EEPROM-level work or ECU updates. We’ll explain these steps in clear English and answer your questions before we proceed.

FAQs
Can you make a new car key without the original?
Yes. We can create a working key even if you’ve lost your only one. Using secure sources, lock decoding, and dealer-level equipment, we cut a new key and programme the transponder and remote to your vehicle. On some models, we use OBD2 programming; on others, EEPROM or ECU/immobiliser programming may be required.
My keys were stolen. Can you stop the missing key from starting my car?
Absolutely. We erase missing keys from the immobiliser memory and re-pair the vehicle only to the new keys we supply. We also re-synchronise the remote central locking. If the mechanical locks are compromised, we can discuss replacing or rekeying lock barrels.
How long does it take to get a new car key?
It depends on the make, model, year, and key type. Many jobs are completed in a single mobile visit, and we’ll give you a clear time estimate once we know your vehicle details. Our mobile service is often faster and more convenient than waiting for a main dealer.
Will you damage my car when gaining entry?
We use non-destructive entry techniques wherever possible and always explain any rare exceptions in advance. Our aim is to protect your vehicle’s locks, glass, trim, and electronics.
Does car insurance cover lost or stolen keys in the UK?
Some comprehensive policies include key cover or offer it as an add-on. Check your policy or speak to your insurer. We provide detailed invoices and written confirmation of key deletion/reprogramming to support claims.
Dealer vs locksmith for key replacement: what’s the difference?
A main dealer usually requires you to bring the car to them and may have long wait times. As a mobile auto locksmith, we come to you, provide secure entry if needed, cut and programme keys on-site, and remove stolen keys from memory—often in one visit.

If your keys are lost or stolen, the priority is to secure your car and get a working key. We’ll explain your options, give you a clear quote, and handle everything on-site with insured, DBS-checked technicians and dealer-level diagnostics.
