Key Replacement for Vehicles


Over the past twenty years or so the security on new vehicles has risen significantly in the UK, with vehicle manufacturers building a far higher standard of locks and the introduction of transponder systems, so your car is more secure than ever before. The downside is that should you lose your keys or have them stolen you may have a real problem.
Vehicle keys now have to be programmed to the individual Engine Control Unit (ECU) to enable them to function. This means that unless your Copthorne locksmith has had specialist training and purchased the latest technology required, they won't be able to help you.

Our Copthorne auto locksmiths have received that specialist training and are skilled at non-destructive vehicle entry (no damage to your vehicle) and this includes deadlocked vehicles.

All our vehicles are fitted with ECU and transponder vehicle key equipment that is updated on a regular basis. Enabling our locksmiths to cut and programme functioning keys for the vast majority of vehicles in our vans at the roadside.


If you need a spare or replacement key we can help even if your vehicle has a remote control or transponder key. With or state-of the-art technology we can do this at the roadside in Copthorne even if all your existing keys are lost or stolen.


Transponder keys what are they?

Your vehicle key has a radio-chip imbedded into it that communicates a code to your on-board computer.
Without this code being received the engine will fail to respond and consequently fail to start.

Our specialist training and equipment allows us to communicate with these on-board computers and programme the new/replacement keys with the code that allows them to work properly.

The majority of modern immobiliser systems require a pin code as an extra security precaution preventing access to the immobiliser’s computer. This would prevent the proper coding of new/replacement keys.

However, our specialist equipment allows our Copthorne auto locksmith to acquire this code thus ensuring your new or replacement keys are supplied quickly and with the minimum fuss.
