    97 Acura RL alarm keeps going off. How can I fix this?



  • Legend92 Sep 11, 2008

    1992 Acura legend, the alarm goes off randomly. Sometimes when the doors are locked and at times when the car is unlocked. Is there a fuse that can be pulled to disable the alarm? Last time it went off the car battery was drained.

    My Car alarm goes off randomly when I unlock the car on the drivers side and the only way it will turn off is to start the engine.

I had same problem, when a door lock broke, the car thinks it has been broken into once the alarm goes off. Mine started going off randomly when this lock broke. You have to reset the alarm system, with my 1990 Acura it was reset finally by putting key in door lock and turning key back and forth 3X. In my car, it was OK to do the key in door lock cycle in the passenger side door lock, but Acura dealer told me not all Acuras will reset it via passenger side key cycling, some require driver door lock key cycling only. I was lucky since my driver side door lock was currently useless, that my car allowed it to be done by key cycle on pass. door lock. But try that and if it doesn't fix it, just call acura dealerships until someone tells you the right answer. In my situation it took 3 dealerships with 3 different answers until this was the right one for my 1990 Legend.

PS I was told you can't disable alarm since it is all integrated into the battery and starting system, but read on another post that someone disableld theirs by disconnecting the horn.

    It was explained to me by dealer that once the car thinks it has been broken into the alarm will keep going off like that, so it needs to be reset (in my case by putting key in door lock and turning it back and forth 3X (cycling the key is what they called it).

It's common for the key switch in the drivers' door to wear out. The alarm can be cleared by using your key in the passenger door instead.

Honda civic alarm keeps going off for no reason


It could be the hood latch. Easy to disconnect just look behind the hood latch under the back edge of the plastic cover,. clipped into metal top frame. 2 pin connectors LT BLU + BLK=wire colors. Connector has a release tab to separate. press down and pull apart. Voila! When you lock the car, you will not hear your horn. Neighbors are happy and you get no more complains.

raise the hood and disconnect the battery. after the dealer disables the system make sure he notes it in the owners manual so the next owner is not on this board a year from now asking about how to turn it back on.

Changed the battery and now the horn blows and the lights flash, and won't turn over.


There is a wire from the drivers door lock to the security system. Try unlocking the driver's door with your key to see if this will disarm the system.

1996 Jeep Grand Cherokee alarm keeps randomly going off.


this happened to me recently with my 96 grand cherokee. the battery got drained by the alarm going off randomly at night. i pulled the fuse for the horn so at least my neighbors would only be bothered by flashing lights. then i couldn't jump the car because the alarm was still going off. i hooked my car to jump it to another car, and then i had to deactivate the alarm first by putting my key in the driver side door and unlocking the car. then i left it hooked to another car and still getting power but didn't jump it for at least 5 minutes in case the computer needed to reset. then it jumped fine. from what i've read online, this is a common problem that can be avoided if you stop using the power locks and always manually lock and unlock the doors with your key. its a little annoying, but apparently the power locks are connected to the alarm issue. hope the same works for you.

Hi, my name is Grace and I have a 1993 Acura Legend. Recently, my car's alarm system has been going off each time I open the door with the key or try to start it in the ignition. I'm unable to drive it...


I had the same problem Grace and even mechanics could not figure it out at first. I called 3 Acura dealers to find answers.

Mine began acting up when a door lock broke and when it broke, the alarm started going off out of the blue.

But.....I want you to know that the drainage of electrical that the alarm drained my battery. Jumpstarted battery and alarm would immediately start back up and drain it again. In the end, it fried my alternator. It was pretty crazy because the radio was going off and on by itself with the alarm blaring and no way to shut it off.

Answer is there is no way to remove the alarm system because it is all integrated in by the factory, Acura dealers told me. Your car thinks it has been broken into once the alarm goes off like that, so keeps doing it. The fix was to insert my key into the driver or passenger door lock and turn the key back and forth 3X. That resets the alarm and stops the whole problem.
