blue bright light indicator light stays on

[jamddi]

I have the blue bright light indicator come on after the 03 H2 has been turned off for 60-90 seconds. When the indicator light comes on if I do any of the following all of the door locks will lock.
1.Open any of the doors
2.Flash High Beams
3.Turn on any inside lights

When I to get gas I typically would leave the key in the ignition, get out to fuel the truck, open the back door and all the doors lock. When I close the door I am locked out of the truck.

Any ideas on how I can fix the problem?
