The most likely cause of this is that the power door lock motor has failed, you will need to replace it. Please watch this video at YouTube.

You may need to remove your door panels (screws are by the door handle, arm rest, under door and side of door) and then peel back the weather film on each door to see what could be causing the issues.. rusted wires, loose connection, broken linkages, seized linkages. I'm not sure what to do with your car since each door seems to be having a different issue, but I would check the locking mechanisms..

you need to take out the door panal and work from the inside of the panal. Open it from there.

you will need to check the door harnesses. the wires crack over time due to the opening and closing of the doors.
check them for broken wires.

if they work from the car door then you will need to have your remote battery checked, if it doesnt work from the car door then chances are there is a lose wire or connection. Also sometimes the knob can get bent and miss aligned. Simple checks are can you hear the the lock trying to lock when you push the button? Do you have two remotes, have you tried the second one?
Hi
The door control module actually consists of the door's Electronic Control Unit (ECU) and the switches or buttons integrated into one assembly. There are two of them: the driver door module or DDM (as seen on the sample diagram below) and the passenger door module or PDM, which is on the right front door. These modules are programmable.
They are also called driver door switch (DDS) and passenger door switch (PDS), so perhaps you can rephrase your search.
