To find out why the lights are on and why the locks don't work, you will have to start by scanning your Body Control Module (BCM) and retrieve whatever fault codes that may be set. Once the fault codes have been retrieved, I can help you with tracking down the correct system/circuits to get the thing working correctly.
Please note: This is NOT the same as hooking up an OBD code reader and reading generic OBD fault codes. This must be accessed with a code reader that can access the BCM and read "vehicle specific" codes.

It sounds like the drivers door switch that tells the body control module that the door is open or closed has gone bad this switch is located inside the door latch assembly. When this switch fails to the open mode the dome lights will time out so that the battery doesn't go dead and if the switch stays open the module won't reset so that the lights will operate.The locks won't work correctly because the control module thinks the door is open same thing for the security system it thinks the doors open when its closed.
