Alarm goes off for no reason. 97 Jeep grand Cherokee.

we cant do that, no idea at all what that means.
no such thing, exists./
post symptoms first so the helper can be on same page.

alarm problem?
cant crank engine?
engine wont start.?
what?

I can only suggest: 1: first replace both remotes batteries.
2: disconect the battery in the vehicle and then reconnect:
3: reprogramme the remotes following the insructions in the manual.

IT is probably just letting you know that it has received the lock signal and has secured the vehicle. Horn beps or clearence lights flask

If the alarm has a siren with a backup battery, then check the condition of the siren battery. Is it drawing a large charge (drop in amps from the battery. Run a parasitic drain test). If so, then the siren could be at fault.

Is the alarm fitted with a sonic motion detector? Looks like two tiny speakers in a unit fitted in the centre of the dash. If so, this unit could be faulty.

Many after market alarm systems by the way, tend to only last for a few short years before failing. Is this an aftermarket product or factory?

Security Alarm Module is located in rigt side box of glove box (attached image) from Repair Manual (Wiring Section).



Hope helps.

How exactly is the alarm stopping the jeep from starting? Is the alarm going off, siren blasting? Is the red led blinking or solid red?

did you figure out what the problem was? Mine is doing the same thing and I think it is drainning the battery.

You may have left a door half open, or have a bad door switch. Until you find out what the problem is you can manually push your door locks with your hand to lock them without arming the alarm and still have your vehicle locked, and not have to worry bout hte alarm.

under the ecu on the right hand side inner wing ,near the fuse box is the siren,un plug and remove the ecu then un plug the siren remove it by any means I had to pry mine off it has its own battery pack inside,I binned mine cos it doesn't affect the running of the Jeep hope you got sorted
