Anti theft system issue
Hi everyone, i will try to make this a short story, when i got my 97 ZJ it came with no remote for the anti theft system so i got one and took it to a locksmith, who is a friend of mine, and he programmed all the stuff correctly, lights and horn flashed well when you armed the alarm system, but the problem began when door lock actuators went crazy, sometimes driver´s door and sometimes any other door didn´t lock or unlock, besides i lost my key with the programmed remote sooo i decided to "help" the actuators with an aftermarket ones (due to high cost of original parts) and get another remote. When i finally went to the locksmith again, he couldn´t program the bloody thing, then i remembered that i didn´t connect original harnesses to the actuators so i did and went to the locksmith again, this time he succeeded and all the doors lock and unlock with the remote BUT...now lights and horn wont flash when alarm is activated and we don´t have a clue about what else to do, any help will be really appreciated....CHEERS

Not sure about your 97 but mine with the 4.0 came factory with only the Lock and Unlock and Panic button on the key. So no flashing lights or horn honk when you arm it. That being said, a gremlin of the system for me was the little bitty switch on the back of the drivers and front passenger door lock cylinder. A dealer tech tipped me to that when I had the battery drain problem with mine, it wasn't letting the system arm and therefore go to sleep.

Yes, mine also has three buttons on the remote, thank´s for the advise and i will search for that switch, it´s important because i don´t know if system is armed or not and my zj sleeps on the street, thank´s again for your time and cheers!!

The sister problem to the front door switches (passenger too) is the tailgate glass switch. All tend to go bad. $14 @ rockauto or $2 at the junkyard, which is the way I fixed it.
