Here's a tricky one.
I opened my car door after thinking i'd de-activated the alarm and the alarm went off, so i re-locked it with the fob, unlocked it, opened the door and the alarm went off again.
I sat in the car until the alarm stopped and noticed the alarm unit on the dash by the window still flashing once per second.
I started the car ok, even though the alarm was going off and the alarm stopped after about 30 secs, and i drove home without the alarm sounding again. The flashing light on the dash was still going though.
Any ideas whats going on and possible solutions?
