When Do You Need a Car Key Duplication Service?
A spare key isn’t just a convenience – it’s a safeguard against the stress and expense of being locked out or stranded. Here are some common situations where our car key cutting and duplication service helps:
- You only have one working key and want a backup to avoid a future lost or stolen car keys crisis.
- The metal blade of your key is bent, twisted, or visibly worn, making it hard to turn in the lock or ignition.
- You’ve purchased a blank key online and need it professionally cut to match your existing lock.
- You’re sharing a vehicle and each driver needs their own key, but you don’t want to pay main dealer prices.
- Your key fob works but the physical blade is damaged – we can cut a new blade and swap it into your existing remote housing.
For modern vehicles with chipped keys, duplication often involves both cutting and programming. If you need a new key from scratch because you have no working original, take a look at our full car key replacement service instead.
Our Car Key Cutting and Duplication Process
We use advanced, dealer-level machinery to ensure every cut is precise – no sticking, no forcing, and no damage to your locks. Our process is straightforward:
- Key identification – We’ll inspect your original key to determine the blank profile, security features, and any transponder chip type. We stock a huge range of blanks for all popular makes and models, from a basic Ford Transit key to a high-security laser-cut Mercedes key.
- Precision cutting – Using specialist manual or electric key cutting machines, we trace your existing key and cut a fresh blank to a mirror finish. For laser cut car keys and sidewinder blades, we use dedicated high-security equipment that can handle even the tightest tolerances.
- Mechanical testing – Before we hand anything back, we insert the new key into your door lock and ignition to check it turns smoothly and operates all locking mechanisms without resistance.
- Transponder programming (if required) – Most keys built after the mid-1990s contain a transponder chip that must communicate with the car’s immobiliser. We can clone many fixed-code chips on the spot or, for rolling-code and encrypted systems, programme the new key directly to your vehicle using OBD2 or EEPROM diagnostics. You’ll leave with a key that both unlocks the door and starts the engine.
We work on virtually every vehicle you’ll encounter in South East London, including Ford, Vauxhall, Volkswagen, BMW, Audi, Mercedes, Toyota, Nissan, Honda, and many more. Visit our brands page to explore your make in detail.

Frequently Asked Questions
Can you duplicate any car key, even if it has a microchip?
In most cases, yes. We can clone the fixed-code transponders found in many vehicles from the late 1990s onwards. For rolling-code, encrypted, or proximity (smart) keys, we may need to programme the new key directly to the car using diagnostic tools, which we handle as part of the same visit.
Do I need to bring the original key with me?
Yes, we need an existing key that operates your locks to trace the blade and read the transponder data. If you’ve lost all your keys, a full replacement service is required – we can generate a new key from your car’s immobiliser data, even without the original.
How long does car key cutting and duplication take?
Most straightforward duplications are completed in 15–30 minutes. If complex transponder programming is needed, it may take a little longer, but we’ll always give you an honest timescale up front.
How much does car key duplication cost in South East London?
The price depends on several factors: the type of key (basic, remote, or smart), whether programming is required, and your vehicle make and model. We offer fair, competitive rates and never charge a call-out fee. For an exact, no-obligation quote, just give us a call.
Can you cut a key from a code instead of tracing the original?
Yes, if you have your vehicle’s key code (often found in the owner’s manual or available from a main dealer), we can cut a fresh blade. If not, we can decode your existing key, which serves the same purpose.
What’s the difference between key cutting and key programming?
Cutting creates the physical blade that turns in the lock. Programming pairs the electronic chip (inside the key) with your car’s immobiliser so the engine will start. Many modern keys require both, and we provide the complete service in one appointment.
