I opened my trunk before I shut off the alarm by unlocking the car and the alarm went off, so I hit the unlock button on the remote fob to shut it off. Now I can't lock the car with the key fob , mine or the extra one and the batteries were just changed. It was working good until I set off the alarm and killed the alarm by hitting the unlock on the fob. Any ideas would be greatly appreciated. They lock OK with the key.
