AFAIK the RAP is not the brains for this. It handles the door keypad and remote fobs. Assuming you have the right keys with the chip in them, the most likely fault is probably a broken transceiver module in the steering column next to the lock cylinder, and that is not coded to a specific vehicle so a junkyard replacement would work, but do search the forum for PATS problems topics.
I do have what I've been told are the original keys, but the guy I bought it from didn't get a remote when he bought it.... I did get one through fleabay, and have tried unsucessfully to program it to the system...
on the module,I was kinda thinking this as well, but was thrown off by the label saying "anti-theft" on the one I picked up from the junkyard.... being that there is no module in behind the rear panel, and no provision for wiring, I'm assuming that it wasn't set up for remote fobs?
side note, I did replace the halo ring yesterday, and the theft light no longer has epileptic seizures, but won't start.... I have my buddies programmer, and will try resetting the system again.... had this running before, but the system had gone back into lockout mode, thinking because of the ring...
wish me luck!
