#5 of 34 Alarm going off by ssgkh

Dec 18, 2008 (4:31 pm)

I bought a 99 Grand Cherokee about 2 months ago and I can't just get out of it and press the lock button on the key and walk away. After about a minute and a half the horn starts blowing and the lights starts flashing. What I've learned to do is upon exiting the vehicle I press the lock button twice and then put the key in the door and unlock the vehicle and then lock it. To recap, I insert the key, turn it to the left and then back right (which locks the doors) and that's it. Then I can walk away. I would really like to know why this alarm system behaves like that and solve this problem. Can someone help me??

#6 of 34 Security alarm/electrical circuit question by lhelfer

Feb 02, 2009 (1:32 pm)

I have a very quirky 93 Grand Cherokee. Have recently replaced the alternator in December 08 and the battery in August 08 but have always had problem with security alarm going off intermittently for no reason. The problem I now have is that the alarm apparently is constantly engaged and has run down my battery. When I hook up the battery charger to attempt to recharge the battery, the alarm is goes off and runs it back down. I got out the jumper cables to try to jump start it, but the alarm goes off each time which won't let you start it. I have an extra set of keys so I used the spare set to turn off the alarm while someone else started it simultaneously, which is the only way I could start the vehicle but as soon as you turn it off, the alarm immediatly comes back on until the battery is dead. Has anyone else experienced this problem and if so, is there a way to disengage the alarm completely?

#8 of 34 Disable the factory alarm system on a 1997 Jeep Grand Cherokee by yourself? by juliet5935

How do you disable it BY YOURSELF? We bought it used and it didn't come with the remote and we can't afford to send it to the dealers because they will charge us an arm and a leg.

Here are instructions, based on advice I found on other websites:
 
To disable the alarm you need to ground a wire that is running throught the drviers door jam wire harness. It is a violet with a yellow tracer wire. It needs to be put to ground.
 
On the drivers side in the foot well area just above the hood release mechanism you should see the wire harness that is coming from the drivers door.
 
In that group of wires, locate the violet with a yellow tracer wire. Do not cut the wire. Instead, strip the violet/yellow plastic off to expose the bare wire.
 
Get a section of new, similar gauged wire (18 guage works), and strip away the plastic on both ends to expose the wiring. Take one end of this new wire and wrap it around the exposed section of the violet/yellow wire.
 
Take the other end of the new wire and ground it to the body of the jeep. This will ground the system and should permantly disable the alarm system.
 
Here is a link that shows a diagram of what I have described:

Hope this helps!
