Replacement Car Keys

Over the years the auto industry has greatly improved the security of their vehicles by using electronic car keys (transponder technology). Although this has proven to have reduced car theft it also causes problems trying to replace lost, broken or stolen car keys.

Consequently as vehicle entry following lockout has become more of a problem, rather than simply having a new car key cut, new replacement/lost car keys have to be programmed; programmed to the vehicle's immobiliser engine management system.

We are trained in the latest entry techniques to gain entry to vehicles without causing any damage even when the vehicles have been deadlocked.

We are also equipped with the latest transponder car key and ECU diagnostic equipment which enables us to cut and programme keys for most makes of vehicles at the roadside.

What is a Transponder key?

The transponder key is a key that communicates with the car's on-board computer (engine management system) via a tiny radio-chip installed inside the fob.

A car's on-board system must receive the correct signal from the transponder key in order for it to start.

Transponder Key

If you need a spare key, or you are locked out and need a replacement car key quickly - we can help. We can even replace your keys without the need for an original.


We can supply keys for most popular makes of car, including the following:

Please Note: Most manufacturers' modern immobiliser systems also have the added security of an access pin code. Without the pin code the new replacement transponder chip key cannot be programmed into the immobiliser system.

We have specialist equipment to retrieve the access pin code from the vehicle's immobiliser system for most manufacturers' models in order that we can program the keys when the access code is lost or not available.

This means you don't have to make multiple journeys to the main dealers to try and obtain these codes or wait up to 5 working days for them.

If your car is not listed, don't worry. We may still be able to help. Please contact us for more information or for a quote.
