Here are the codes you posted along with the possible issues that may have caused each code to be triggered. It's possible the circuit these switches share has a problem that needs to be diagnosed.
It could well be a problem with the wiring or a problem with the connections between the switches and the Multiplex Control Unit, or possibly with the Multiplex Control Unit itself.

Door Lock Actuator Lock Control
you have to take off the door panel and look. most often the linkage comes off of the outside handle; sometimes something is broken. It will be a mystery no more when you remove the door panel and look.
I tried replacing battery in my remote. Sometimes it work and sometimes it doesn't. I think it could be a wiring problem in the remote. I know it's a major paun having to hurry up and put key in ignition befofr alarm starts going off.
lock with key,electric door lock button,or remote and alarm will set. to disarm you have to use the key or remote to open it.the reason it woulnt disarm from drivers door is either the door lock cylinder switch is broken or the wire to it in the rubber boot that connects the door and the body is broken.
the remotes are cheap and programing is easy,procedure in owners manuel something like lock drive door with elkect. lock switch with door open then push and hold unlock untill doors unlock then turn key off.you may have to fix that drive door lock cyl.switch first though mabee not dont know for sure
the solenoid may be weak, or it can be lubed. you will need to remove the door panel and see how it works, and try to lube it, or see if there is any binding.
have someone from the outside pull the handle up while you pound the door from the inside. the latch became frozen from lack of lubrication. once open, spray the **** out of it with wd40 or pb blaster and work the latch till it moves freely
You can't lock the car when any of the doors are open EXCEPT with the door "Lock" button on the driver's side door. The remote will not lock the car when any of the doors are open.
Check door switch connection under door pad in drivers door. Sounds like the electrical connection that sends power from the main door (drivers side) to other door has failed or wiggled loose.
