I have a 97 Jeep Grand Cherokee with 250K miles on it. It has the 4.0 with the Select-trac transmission. I bought it from a police auction back in August. Drove it home. Cold air, 4 wheel drive worked great, ran great, no problems.

I have searched this topic over and over again, and now I am looking for any solutions. I am ready to trailer this ZJ to the scrap yard.

I put a new fender, new front bumper cover, and new passenger headlight in it. Washed it, cleaned it, had it looking good, decided to lock the doors.....

When I say, decided to lock the doors, that was the last time this ZJ ever moved. I armed the factory security system. I have no key fob, I have the factory key. I have tried everything. I have ground the wire in the drivers door. I have twisted the wires together in the drivers side door. I have locked and unlocked every door infinite times. I have locked myself in, had the battery hooked up and then tried to start it.

The only results I get, 3 seconds of running, then dies. Lights flash, horn goes off, wont run. Still fires up fine, wont run.

I have tried holding the battery terminals together to reset. I have a fully charged battery.

I feel like I have tried everything, so somebody please give me an idea or something.

This is my 20th Jeep. Many XJ's, CJ's, YJ's, a few ZJ's.

I am lost and soon I will be scrapping this ZJ, I guess. I dont want to take it to the dealership and get reamed out. I know that might be the only solution.

Anybody? Anything?

It's in theft mode and there is no way of reversing that without the dealer's help, sorry.

N2odart

Because it thinks its been stolen? HMMMM. So the dealer can take it out of this mode on a scanner/computer?

Hey N2odart,, glad to see a fellow hoosier here... Called a friend of mine at dealer, said it is in stolen mode and can be fixed but needs to have the computer reflashed.. at least I think that is what he said... I don't think that is what he ment but there is voodoo involued.. Ha Ha..

call a local dealership and see if they can fix and how much. if its reasonable or worthwhile in your eyes, tow it to dealership.

just a random thought, would disconnecting the battery work? like i replaced my battery then i couldnt pass emissions because i hadnt drove iit enough for the computer to be fully reset and ready. maybe if its disconnected then reconnected it will "forget" it was in stolen mode lol

The Rooster

disconnect the battery see if the ecu resets

Like the guy said, they'll Flash the ecu and you need to buy a Key fob.

unfortunately thats your only option.
it will never come out of theft mode without a reflash.
Sorry man

i had this same problem just last week and i just wanted to scrap my 94 grand..i googled how to reset the the alarm and what i found out was pretty surprising. I locked and unlocked the rear hatch 2-3 times and it reset the alarm!! I am just glad i didnt pay someone to figure that out haha. Hope this helps, let me know if it works.

I will break down and take it to the dealership. Like I said, I locked and unlocked everydoor and tried grounding the door wire, and tried twisting the door wires together. I think the reflash on the computer is the only answer. I will post the results in a few days and a few hundred bucks later.

did you try the hatch?
that was the only way my brothers alarm would disarm.
