bought car that had issue self locking at first.
went to dlr, asked "you get remotes for these still", "why yes , here it is $56...ish later"
i programmed it just fine as well, my range has been normally a good 200 feet as the shop i work at tons of people set off the alarm all the time. i did find that the horn and lights were disconnected when i bought the car in march. i love how well it works im hounding the yards for another unit.
at times it self arm sucks, but horn defeat part works as well as valet only. the "glass break" works very well. i park in a garage every night, im very sneaky. i grab my garage remote to walk upto my house and it usually sets off my alarm.
i do have the factory service mani, as well as wiring diagram. if i do ill have to draw it up i guess
