I recently bought a 1999 Cherokee and ever since I bought it, the anti theft system automatically turns itself on after about 30 seconds of getting out and shutting the door, even without locking the door. Then when I open the door the alarm goes off (which consists of the parking lights blinking and the ignition System disabled) until I hit the unlock button on the key fob. So when I go out to grab something out of the jeep and I don't have the key since I know it's unlocked, the alarm goes off for 10 minutes or whatever. I've been redoing the suspension the last little while and every time I do anything on it the dang alarm goes off and there is nothing I can do about it unless I track down the fob and hit the button. (in hind sight I could have removed a terminal from the battery) this is annoying because it goes off literally every time I bump the jeep around at all. have any of you had issues with the Cherokee anti theft systems?
