I have a viper 550 ESP car alarm in my hatch and it doesn't work anymore!? It won't arm anymore, obviously it won't un-arm either. It started out being a pain to arm and un-arm and then one day I had to just open my door and let it go off as I just kept pushing the un-arm button and it finally went off after a bit. after that i just haven't armed it again. then the other night after i got off of work i tried it for shits and giggles and it worked?? when i got up the next day and tried it again, it didn't work anymore?? I changed the battery in my remote and that did absolutely no good. it seems to want to work after i have been racing or the car is hot?? any suggestions would be appreciated though!
