well my o3 msp alarm started to act up what happens is i lock the doors with the remote but dont arm the alarm well so i think. a while later theh alarm is going off could be 10 minutes or 6 hours. ok hit the unlock button a few times shut it up. walk away with doors unlocked all of a sudden honk and doors lock. couple min later alarm again. of course it wont do it at the dealer so they say cant fix it. car is all stock. any ideas?
