Re: Cheap ways of getting new keys?
Well there are three parts to the key:
The pattern of the metal bit, that unlocks the steering column and works the ignition switch.
The RFID chip for the immobiliser - contained in a little bit of plastic or glass inside the key.
The code that the key sends via radio to set/unset the alarm and open the central locking.
Shaping the metal bit is easy on a blank key, very hard on a already cut one.
The immobiliser chips can only be coded once, but have to match up with the vlaues stored in the ECU
The radio code can't be chnaged, and so has to be learnt by the alarm controller.
A good high street key cutting place (like Timpson) will be able to make you a new key, and code the immobiliser chip (for about £15). But they won't be able to do the alarm remote.
