I would think this has to be the security system.

I believe the symptom is that the light stays on in the hazard switch if the problem has occurred - check it an hour after locking the car and if it's on, do the battery disconnect!

Now your battery has gone flat I suspect the modules will have reset already. Battery should be fine after a recharge.
