What We Replace And Repair
Modern cars use different types of keys and anti-theft systems. We work with all makes and models, including Ford, Vauxhall, Volkswagen (VW), BMW, Audi, Mercedes-Benz, Nissan, Toyota, Peugeot, Renault, Kia, Hyundai, Land Rover, and more.
We provide:
- Standard transponder keys and remote fobs
- Smart keys and proximity keys for push-to-start systems

How Our Car Key Replacement Service Works
We’ve refined a simple, transparent process so you know exactly what to expect.
- Assessment and Security Check
- We confirm your vehicle details (make, model, year, fuel type, transmission), location, and proof of ownership.
- We ask about symptoms (lost, stolen, broken, water damage, or not starting) to prepare the right tools and blanks.
- Non-Destructive Entry If You’re Locked Out
- If your key is locked in the car or boot, we use non-destructive entry techniques, specialist picks, and air wedges where appropriate to open the vehicle without damage.
- Only in rare cases (e.g., severely damaged locks) would we discuss any invasive methods first. If needed, we’ll explain options clearly before starting.
- Key Cutting
- We cut your key on-site using precision machines, including laser cutting for high-security blades.
- For vehicles with security key codes, we can decode from the lock or obtain codes securely where authorised.
- Programming and Sync
- We connect dealer-level diagnostics to your vehicle’s OBD2 port to program transponder chips and remote functions.
- For certain models and situations (e.g., all keys lost, immobiliser lockout), we provide EEPROM key programming and ECU/immobiliser programming North London to pair new keys safely.
- We test central locking, remote start (if applicable), and immobiliser recognition.
- Final Checks, Advice, and Warranty
- We verify that all keys work correctly in the doors, boot, and ignition, and that the car starts reliably.
- We provide usage tips, battery advice, and security guidance, plus your written warranty on keys and workmanship.
If your priority is getting back into the car first, our car unlock service North London can help you gain quick, damage-free access before we replace or program keys.
Advanced Diagnostics And Programming
Modern cars rely on sophisticated immobiliser systems. That doesn’t mean you have to go to a main dealer and wait days. Our mobile auto locksmith North London vans carry:
- Dealer-level diagnostics for key learning, remote programming, and fault code checks
- OBD2 interfaces and software for a broad range of brands, including 2024/2025 models
- EEPROM tools for vehicles requiring direct immobiliser/ECU data handling when all keys are lost
- Specialist cutters for laser cut car keys and high-security profiles
A transponder is a small chip in your key that talks to your car’s immobiliser. If the chip isn’t recognised, the car won’t start. We solve this by precisely coding your new key’s transponder to your car. For smart/proximity keys, we also match the keyless entry and push-to-start functions.

Non-Destructive Entry And Your Vehicle’s Security
We use non-destructive entry methods wherever possible. This protects your paintwork, window seals, and locks. Methods include:
- Lock picking and decoding using vehicle-specific tools
- Air wedge and rod techniques applied professionally to avoid damage
- Remote synchronisation and emergency blade usage on smart systems
Rare exceptions
- If a lock is already damaged, severely corroded, or has been vandalised, non-destructive entry may not be possible. We’ll explain the risks, obtain your consent, and replace any components as agreed.
- Where insurance or police guidance requires immobiliser reconfiguration after theft, we will erase old keys from the system so stolen keys no longer work.
We never cut corners on security. If you’ve suffered a theft, we can delete stolen keys, add new keys, and review options like door lock changes or steering lock repair if appropriate.
