Cant turn off jeep alarm

put key in ignition and turn it to reset or turn off alarm when you unlock with key not fob vehicle thinks its being broken into

Use your key to turn the rear hatch key cylinder before going into your jeep. That will turn off the factory security system.

Sounds like you have a key without the chip in it. Replacement keys without the chip will only unlock the doors and will activate the theft alarm when you start the vehicle.

is the alarm after market ? and is so you need to replace it with another after market one .. now if the alarm is factory ?...you will need a remote control from the dealer and they will reprogram it for you

There is a security system built-in to the Jeep Grand Cherokee during these years. The reason the alarm goes off is because of a change in the electrical system (like shutting a door) that triggers the alarm. To stop the alarm, either disarm with the remote or unlock the door from the outside with the key. This will shutoff the alarm.

Normally you can get the alarm to shut off by puttin ght key in the ignition or in the door and turning. The remote will need programed with the vehicle. Should run about 50.00 or so for service department to do this. My wife has a '99 cherokee and it did the same thing. I know the remote is the problem.

Is the alarm the factory alarm or is it aftermarket? If it is the factory unit try using the remote fob to turn it off (check batteries in the fob). If you lock the car door and reach in the window and open from the inside door handle it will trigger the alarm. Stick the key in the door lock and turn to unlock. It's been awhile since I looked at these Jeeps so memory may not be clear.

If you cant start it because of the alarm disconnect the battery, wait ten secs, reconnect then turn the key in the driver's door twice holding for 2 seconds on the second turn, this should reset the alarm.

The ignition security on/off is located at the trunk lock. unlock and lock rear gate and the alarm will turn off. My jeep sat in my drive for a month before a jeep tech told me this. It still triggers the security sometimes when I unlock the passenger door with the key and I go straight to the rear gate lock and it shuts off instantly.
