Default Factory Keyless Entry...screwed-up by After-Market unit.

I have a new to me 1996 Bonneville Se. Previous owner put in a Pursuit alarm system,
in order to make it work it appears that the door lock wires Driver and Passanger were jumpered I think the Drivers side door and the Passanger door lock/unlock..probably so all doors would open with one push and lock with one push of the same button

Any way a local alarm company said they can't get new transmitters to program..the alarm must be bad. 2 days later at a GM dealer a tech says that he can't get a new GM remote to program. there must be something wrong with my contrrol unit I am wondering if the splices to the door locks are preventing the factory remote from programing?

Spit, I'm assuming your objective is to restore the keyless entry to normal operation. I would recommend removing the aftermarket alarm system by removal of any integral wiring and components (disabling) associated with the aftermarket system. You will probably need someone with a 96 fsm to help you out. Jrs. 3800 has extensive knowledge on keyless entry, maybe he'll chime in.

Spit.. last I saw in another thread you were considering removing it, correct?

If you can't get remotes, don't know if it works and seem to have other electrical issues that may be a problem, I'm unsure why you are trying to still get this to work while knowing it may be part of your problem

I am planning on removing the after market alarm. I would be happy to have either the after-market or the factory keyless work but I think the alarm is shot.

I am considering getting a factory remote off of E-bay or something...I was asking the question about the wiring, in an attempt to confirm that the factory reciever is operational before buying a remote that may not work. I was hoping that someone else has had a similar experience and could confirm that this alteration of the wiring will prevent factory remotes from being programmed.

Is there any way for me to know it the reciever is operational short of buying the remote? I wish I knew someone who had a working remote with the right FCC ID that I could try to program to the car after I have removed the aftermarket alarm.

I would think not, but who knows for sure. Get those splices out of there, restore the door lock wiring to normal. Remove any existing interface with the aftermarket alarm. Now you can establish what is going on with keyless entry. Worst case scenario if after you buy a new remote (fob), you may have to get a new receiver module for inside the car. There is a procedure in the owners manual for initializing the remote after you replace batteries or get a new one.

I know a little bit... On the 96 + I believe that they call this the MALL Module ... But the system is a bit intertwined.... I'd have to look at the 96 wiring to get a better understanding... But you do need the schematics so that you can restore the Keyless system back to factory wiring... Then from there you should be able to repair the system...

Typical alarm wiring in our setups don't require cutting of the wiring only splicing into it.

Default Removing After market Alarm

I am going to remove the after-market alarm this week. Now that I've got the fuel sending unit replaced and working (knock on wood) I may go ahead and order a remote on e-bay and try to program it again with all the junk out of the system...I know the after-market alarm it shouldn't prevent the factory units from working...but I wonder about programing new remotes when all the door(driver'* and passangers) are wired together...If the unit is running any type of self check maybe that can screw it up...

I'll post what happens.. Thanks to everyone for your input, this site is amazing, some of you guys with the 2 and 3 thousands posts might take it for granted, the quality of the information and participation etc. but for a rookie like me it'* just freakin' awesome how much you all know.. .. WHAT A FANTASTIC RESOURCE.

Thanks again

Spit
