Bump from the dead...This happens to me about once a month and happened to me yesterday...While this is extremely annoying to be driving with all interior lights on, at night, along with the constant chime, what's worse is parking the car...When you go to arm the alarm or more importantly try to lock the door, it refuses to...Guess it's an anti-lockout feature, if you try the lock the doors, they immediately unlock...

What do you guys think?

 

The module can be read and tested but needs specialist jag software (IDS, WDS etc, AE). Most likely it's the lock / its solenoid etc.
