We bring 10+ years’ experience, DBS-checked technicians, and public liability insurance to every job.

All new keys and programming are backed by a 12‑month warranty.
When You Need Car Key Programming
If any of the following sounds familiar, you likely need programming rather than a simple cut:
- You’ve replaced the key battery and the fob still doesn’t work
- Your car shows a key or immobiliser light and won’t start
- “Key not detected” displays for push-to-start vehicles
- Central locking works intermittently or on some doors only
- A new or spare key isn’t recognised by the car
- You’ve lost your only key and need a new key programmed from scratch
- ECU, BCM, or immobiliser modules have been replaced or updated
- The car was jump-started or had a flat battery and the key lost sync
If your situation involves lost or stolen keys and you want them erased from the vehicle for security, we can safely remove old key data and programme fresh keys. If you also need a physical key cut, see our Car Key Replacement.
Transponder and Smart Key Programming
Most modern cars use immobiliser technology to prevent theft. Inside your key is a transponder chip that “talks” to the vehicle; if the chip isn’t recognised, the engine won’t start. For newer models with keyless systems, a proximity fob communicates wirelessly so you can start the car with a push button.
We cover the full spectrum:
- Transponder key programming North London for standard chipped keys
- Smart key programming North London for proximity/push-to-start vehicles
- Keyless entry programming North London for remote central locking
- Remote key programming North London when buttons stop working
- Anti-theft key programming and secure key erasure if keys are lost or stolen
Our tools include dealer-level diagnostics and OBD2 key programming in North London, allowing us to connect to the car safely and add, remove, or re-sync keys. Where needed, we can retrieve immobiliser PIN codes and programme keys offline.
Key Fob Programming Service and Repairs
If your remote is unresponsive or only works at very close range, it may need reprogramming rather than replacement. We provide:
- Key fob programming service in North London to re-sync remotes to the car
- Key fob repair North London for worn buttons or cracked housings
- Flip key repair and key blade replacement
- Replacement remote shells, batteries, and high-quality aftermarket or OEM fobs
If your fob repeatedly fails, the issue may lie in the vehicle’s receiver, central locking module, or a battery/ground fault. We can diagnose and resolve remote central locking problems on-site.
ECU and Immobiliser Programming
On some vehicles, especially newer models from brands like Ford, Vauxhall, Volkswagen/Audi/Skoda/SEAT, BMW, Mercedes, Nissan, Toyota, Peugeot, Renault, Kia, Hyundai, and more, key programming involves the ECU or Body Control Module (BCM). We offer:
- ECU / immobiliser programming in North London
- Secure key addition and erasure using dealer-level equipment
- Immobiliser PIN retrieval for many makes and models
- Software updates and adaptations if a module has been replaced
This is often required for lost-key situations when no working key is present, or after an ECU/BCM change. Our technicians are trained to handle these procedures safely, protecting your vehicle’s electronics and data.
EEPROM and Advanced Diagnostics
For certain vehicles, OBD2 programming is not possible or secure enough. In those cases, we use EEPROM techniques:
- EEPROM key programming North London: reading immobiliser data directly from the chip
- Bench programming for modules removed from the vehicle
- Micro-soldering and specialist tooling where required
- Non-destructive procedures wherever possible, with full explanations before any component removal
EEPROM work lets us create keys even when all keys are lost, or when an immobiliser is locked. We’ll advise you on the quickest, most reliable path to a working key without towing to a main dealer.

- We come to your location and complete everything on-site

We’re happy to advise if a dealer route is better for a specific vehicle or security update.
FAQs: Car Key Programming in North London
Can a locksmith make and programme a car key without the original?
Yes. Using dealer-level diagnostics, PIN code retrieval, or EEPROM techniques, we can create and programme new keys even if you’ve lost your only one. We’ll verify ownership and securely erase any missing keys if requested.
How long does car key programming take?
Many jobs are completed in 30–90 minutes once we’re on-site. All-keys-lost and EEPROM cases may take longer due to data extraction or module work. We’ll give you an estimated timeframe during your quote.
How much does car key programming cost in North London?
Costs vary by vehicle make, model, year, key type (transponder vs smart), and whether we’re adding a spare or replacing an all-keys-lost scenario. For clear guidance and a tailored estimate, see auto locksmith prices in North London and contact us for a firm quote.
Can you reprogramme a used car key fob?
Sometimes. Many used fobs can’t be reprogrammed if they’re locked to another vehicle, especially on newer models. In other cases, we can “unlock” or adapt them. We’ll advise the best route—often a new or virgin fob is more reliable.
My car says “key not detected.” What should I do?
First, try a fresh battery in the fob and hold it near the start button or steering column (often there’s a backup antenna there). If it still fails, the fob may need programming or there may be an antenna/receiver issue. We can diagnose this at your location and programme a working solution.
Do you cover evenings and weekends?
Yes. Our mobile service is designed around busy schedules in North London. If it’s urgent—locked out or stranded—visit our Emergency Auto Locksmith North London page or call us.
Does insurance cover lost car keys in the UK?
Some policies include key cover, either as standard or an add-on. Check your documents. If you have cover, we can provide invoices and documentation for your claim.
