Question

i have a 1993 jeep cherokee and it has a built in alarm.when you lock the doors the alarm sets.when i unlock the jeep on the drivers side the alarm goes off,when i unlock the jeep from the passenger side it doesnt set the alarm off.does anyone know whats going on with my jeep?

Answer 1

There is an electrical switch on each front door lock on this vehicle that signals the alarm system that someone is unlocking the door with a key. The problem is most likely that you have a bad key cylinder switch. A competent technician can test the system with a scan tool, and verify that the switch is indeed defective. Note, it's also possible that a wire for the switch is broken between the driver's door and the a-pillar. This is common on Jeeps, and is the first place I would check. But you'll most likely find a defective switch. HTH!! Good Luck!!

Answer 2

Not sure about Jeeps, but our Chev alarm goes off if you unlock with a key after locking it with the keyless remote.

Answer 3

The alarm is electronic. So if you unluck it via the key thus bypassing the electronic system the alarm computer will not know thus it will see it as a intrusion.

If you have like a lexus the locks have sensors for keyed entries thus you dont' have the problem.
