How to disable my theft alarm.

I have a 1990 Chrysler Imperial with a theft alarm that keeps going off, or it won't disarm after I unlock the car, and I can't get the car started. I use to disarm the alarm from the drivers side door, it won't work from that side anymore. A AAA man told me that the system is getting old and beginning to ware out on the drivers side door, now I have to disarm it on the passenger side. This is only a 2nd car that I drive to work, nothing special. Is there anyway to disconnect this alarm system and still be able to start the car? I really don't need the alarm to work , I would rather know the car was going to start when I get in it. I don't know if I can disconnect this alarm and still be able to start the car. Any idea's?

 

is this a factory chrysler alarm system or an aftermarket alarm system?

 

I have never try to disable the system so I'm not sure if pulling the "security fuse" will works or not, however, I've fixed so many problem as yours as simple as replace the arm/disarm switch which locates right behind the door lock cylinder. Just a though.

 

This is a factory Chrysler alarm system. Something keeps setting this alarm off, maybe it is a bad switch in the door. If I can just disconnect the alarm, I think I would rather do that first.

 

I misread your original post.

I'd try to disconnect the hood switch first then if it's still goes off by itself, try the trunk switch, I've seen lots of them goes bad that would set off the alarm for no reason.

 

If this is a factory alarm then chances are disabling it is not going to be as simple as pulling a fuse or disconnecting a switch. If it is keeping your car from starting then it must run through the powertrain management system (computer or module/s) so you would have to have a pretty good understanding of the circuitry and logic behind it to effectively disable it mechanically. DO you have an owners manual for the car? Many times there is a simple procedure (such as a combination of ignition key turns and door opening, etc...) that you can do to actually disarm the security system without having to cut wires and stuff. If all else fails, I would call up your local chrysler dealer and ask them how big a deal it would be to disable it and they may be able to tell you the simple procedure I mentioned or at least could give you a quote on how much if they disarmed it....you never know, may not be too much. IMHO you can really screw some stuff up (such as frying the computer) if you start pricking and probing on wires that you don't have a full understanding about so if I were you I think I would be careful...you may end up with something worse than what you have now. IF you talk to the dealer and there is no simple way to turn it off then your best bet may be just to order the drivers side switch and put it in...it sounds like that would probably fix your problem.

 

I'll check in the owers manual, if I can't find anything in there, I'll contact Chrysler. Thanks................
