Ok I bought this system off ebay, and saved a few bucks, I installed it myslef and saved a few more. But I am 99.999999% sure its installed correctly because every part of it works. Ok now heres the catch, every once in a while, say every 6-8 unlockings it does its normal Beep Beep, and the lights flash, but the door locks don't unlock. I then press again to lock the still locked doors, and then try to re-unlock them and they unlock. It only does it when trying to unlock the doors, and when I try to re-unlock them it always unlocks. Anybody had this or have any idea whats wrong?
