Well someone stole my keys, and now im using the 2nd set. I wanted to know if it was possible to have the PATS System changed to not accept the old keys, and just program the one i have left to match it? Also, how would i go about putting a kill switch in the car. I know how to put them on old cars, but how would you instal one on a new gen car? Any help would be nice, Venix.
