Car Rekeying in Ashton-in-Makerfield

Full Car Rekeying in Ashton-in-Makerfield

Standard key replacement removes one lost or damaged key from the equation — but it doesn't guarantee that another copy of the original key can't still operate the vehicle. Car rekeying goes further: by replacing the physical lock barrels and erasing all transponder data from the ECU, it ensures that only the new keys — in your possession — can access and start the car. It's the automotive equivalent of changing the locks on a house.

When Is Car Rekeying the Right Option?

Car rekeying makes sense in several situations:

• Second-hand vehicle purchase — you have no way of knowing how many keys were made for the vehicle or who has copies
• Key theft — even if the key is later recovered, you can't be certain it wasn't cloned
• Domestic disputes or shared vehicles — where you need to restrict access to specific individuals
• Fleet vehicle turnover — ensuring departing drivers can no longer access vehicles

What Car Rekeying Involves

The process covers three elements. First, the door lock barrels (driver's door and passenger door at minimum) are replaced with new units. Second, the ignition barrel is replaced to match the new door key profile. Third, the vehicle's ECU is accessed via OBD diagnostics to erase all previously registered transponder codes and programme fresh codes for the new keys. The result: physically new locks, electronically new key codes.

New Keys Provided

Car rekeying includes the supply and programming of replacement keys — typically two. These are cut to the new barrel profile and have transponder chips programmed to the now-clean ECU. If the vehicle uses a remote fob or smart key, those functions are programmed in the same session.
