Montero Alarm Issues - intermittent door lock / unlock
 

I have 98 Montero Full size and a few times a day, the doors will intermittently lock and unlock for no particular reason (chirp, chirp chirp!!!). Once in a while, the alarm will also go off, even when sitting quietly in my garage.

I've removed the batteries from the keyless entry fub, thinking there may be a short in the fub - but it still has the problem.

Any help or recommendation would be appreciated on how to fix this problem, or simply disable the whole alarm system!

Thanks

3 chirps, there must be a short in your wiring/ relay for the alarm,

or what happened with my monty, is that other peoples keyless entrys set off my alarm....wish i could tell ya more but i got rid of my 98 monty a long time ago,(rip)

Is your montero equipped with keyless F.A.S.T. System? If so, please have the external button on the handle (button on the outside handle that you press to lock the car while key us in your pocket) check it because it might be stuck at a pressed position.
