Lock
You can open a key lock on a door knob, or you can open a deadbolt lock on the door itself.
it shuts off when you open the driver side door....
I have a 05 Envoy XL Denali, and yes the radio will shut off when you open the door after the key is removed
I think this is a safety measure to keep you from locking your keys in the car. Try locking it with the key after the door is shut.
Put key in ignition, turn to on position. Open driver's door and remove key (keep door open). Put key in and out 4 times without any turning of key. With the key out at the end, hit drivers side unlock button 5 times within 10 seconds. Wait at least ten seconds and shut the driver's door. The auto lock should be disabled now!
Surely there is a key lock on the door where you can insert the key and open the door.
Key will turn but door won't unlatch to open.

This might help. Unlock the door with your key, open it,shut it and lock with your key. Wait 20 seconds and unlock the door with your key. My alarm system shut down my ignition one day making it so that I couldn't start the car. My friend a radio tech told me this and it worked.
In the radio tower you will fin d the basement key. After you get it stand in front of the grey part of the door and press A it will open.

Use the key to open the door.
