pizzaguy has it right on.

My understanding is that these remotes do not lock to specific vehicles, the transponder does.

The FOB/Remote can be reprogrammed to other vehicles by inserting the key into the ignition switch, press either the unlock/lock twice, then turn the key in the ignition to the ON position within 30 seconds. So in a way, it is a universal remote. Have I tried it on a crossfire myself, no. But I would like to own one and upgrade the engine to a V8 along with testing out all immobilizer theories .
