I've heard of some GM (cadillac) vehicles that have a keyless entry system
that does not require a remote.
basically what happens is once you get within a certain distance of your
car, a chip (or some other device), transmits a signal that unlocks the
doors. ok, so its obviously i'm not real sure of the mechanics but it sounds
has anyone heard of it? know where i can find information on it? any
aftermarket retailers selling it?
drop a line.
