2004 Grand Cherokee Alarm Goes Off When Using Key in the door lock

Asked by GuruLWHWH Mar 28, 2019 at 09:30 AM about the 2004 Jeep Grand Cherokee Limited 4WD

Question type: Maintenance & Repair

I have a 2004 Jeep Grand Cherokee Limited and when I use the key in the
driver's door to unlock it, the alarm goes off.  The only way to open the door
without setting off the alarm is with the remote.  Should the remote battery
die, I would be stuck as I couldn't open the door with the key without setting
off the security alarm.  Is there an electronic part on the door lock that may
need replaced?

Had same issue with my 2004 Jeep Liberty. I read disconnecting battery for a few minutes and reconnected resets system. It worked for me!

Had the problem of intermittent unnecessary alarm. Opened both the terminals of battery and cleaned, waited for 3 minutes, reconnected and started. Run 40 Kms. No alarm! May be due to the terminals were not conducting properly, due to corrosion/ unclean surface.

That worked! Cleaned off and tightened terminals and the car now unlocks without tripping the alarm. Thanks to whoever came up with this.
