As said earlyer in the thread it can be done but when ive fitted these to cars ive always cut the spare key to pieces to get the chip out and then glued it to the ignition barrel,these should only be fitted to auto cars but ive just made customers sighn disclaimers

.
It is however a good idea to check its not in gear as ive seen 2 cars kangarooing down the street outside my work and put my rs turbo in to a wall outside the pub one night

funny but lucky for me no damage and know one run over.
