Hope so. Keep in mind the reprogramming process I have read through seems to say connections to prior remotes will be lost. You will need to reprogram the old one again.

I also recall someone having issues like yours, and he reprogrammed it. Started working as if it was new!
Maybe the process will rejuvenate the old remote, giving you a spare!

I can sort of see how this could work (WARNING: speculation ahead!)

1) Immobilizer is programmed to recognize certain signals from its associated remotes.
2) Fob malfunctions in a way that slightly alters the signal it transmits
3) Immobilizer can no longer consistently recognize the malfunctioning fob.
4) Reprogram immobilizer to relearn all fobs - immobilizer learns the "bad" signal of the malfunctioning fob in the process
5) Malfunctioning fob transmits "bad" signal, but is now recognized by immobilizer, so everything works OK!

Thanks techman and Dave. The fob should be in Friday from the dealership. Hopefully, it will work and that'll be that.

I think travanx has the right idea. If any of the items the immobilizer monitors are not in the correct mode, the system will not arm. Check your owners manual for the list: door switches, interior lights, glove compartment light, trunk and engine compartment closed and lights off, radio ground, etc.

I will do that this afternoon, nc trackrat. Let me get this straight, though. If something as little as the glove box doesn't think it's closed the immobilizer won't arm! If that's the case and it is something like that I guess I have a new, spare key fob.

The alarm system monitors all those things, I don't think the immobilizer does. The immobilizer works independently of the alarm system.

Even if the alarm is not in a "ready" state, pressing of the remote should cause the indicators in the door to flash. Sends a signal to the alarm. The alarm will look at all of it's inputs, and if not ready, it will not arm. Dave is right, immobilizer is not watching those.

Rennsportsystems charges $1000. It does seem like a lot, but, at least you don't have too worry about any more. And you won't need a flat bed. You can alway install a private security system if you feel the need i.e. battery cut off etc.

To remind those who have tried to help, my late '95's fob wouldn't activate the immobilizer to lock the car up and I felt the need to lock it with the key rather than leave it overnight in a parking lot unlocked. I've got the new fob, but to get into the car I had to open it manually with the key and it set the alarm off. I disconnected the negative terminal to stop the horn, so now when I reconnect it the horn starts in. Of course, the old fob does nothing. Anybody know what I can do? Thanks

Check your manual. I'm not sure about the '95s, but on my '97 there is a procedure where you enter the 4-digit alarm code (similar to how you enter the code to learn fobs) to get the alarm to shut off.

Thanks, Dave, but there's nothing in my '95 owner's manual about that procedure. If no one else pipes in today with anything I guess I'll flatbed it to the dealership

Ned,
Hang on just a little. I will look in a pdf of the workshop manual and see if I can pull out some pages for you.
