Disconnect the negative cable first and then the positive cable and remove the battery. The lights/alarm will go out when battery is disconnected and may come back on when reconnected. Use door lock key fob to shut alarm/lights off if they come back on when battery is reconnected
that will require someone with a laptop program to be able to communicate with your vehicle... Not an easy task and you might be stuck with having to replace the BCM...
holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.
The security alarm system on the 1994 Jeep Cherokee arms itself on any normal exit from the vehicle, i.e. ignition off, open door, lock door with power door locks, close door. If the doors are locked with the key, it does not arm. If the battery is disconnected, then reconnected, the alarm system will go into powerup alarm mode. The lights will flash, but the horn will not blow. The alarms can be disarmed by a keyless vehicle remote or by unlocking either of the front doors or the read lift gate with the key. If the key method does not work with any of those three entrances, there is a problem either with the input to the alarm module or the module itself. There is a switch in both front doors and the tailgate which is activated by manualy unlocking those doors. The alarms can be disabled by permanently grounding the wire going from either of those switches to the alarm module, but this will remove all theft protection. The best thing to do is to find out why the system is going off in the first place. It could just be a glitch, a loose connection that can be fixed fairly easily and keep your theft protection intact.
LOL... MINE DID THAT ALSO ONE TIME THEN WE FIGURED OUT IF U REMOVE THE FUSE IT WONT START AND IF IT DOES IT WILL ONLY ALLOW U TO GO 20 MILES THEN IT SHUTS OFF!!! ITS A SECURITY FEATURE!!! SO IF IT EVER GOT STOLEN THE THEIF COULD ONLY GO 20 MILES UP THE ROAD!! I WOULD PUT THE FUSE BACK IN AND GO TO THE LOCAL NISSAN DEALERSHIP AND GET A NEW REMOTE!
