Re: how to disconnect alarm in 2000 cherokee
If you have the basic alarm system, you could just remove the horn relay in the PDC to stop the sound. Did you replace the remote control batteries as well? It can be that you have to press the unlock button up to 8 times to synchronize the system again. I think that you should also be able to disarm the alarm system by using your key in the drivers door lock (with the battery connected).
