First make sure that the rear wiper is parked all the way down in the receptacle on the door, if the wiper is not down all the way for some reason the window will lock. Next check the motor itself by removing the rear inner panel and the metal plate, apply power from a 12 volt source directly to the motor, unplug it and ground one side and power to the other, the reverse connections if there is no response from the motor replace it, if the motor works this way a common problem is the back door ECU.

I shows that it is located in the engine compartment fuse box.

Sounds like your door lock cylinders are shot. If you remove your door card, find your lock cylinder and see if you are missing something, or something has come loose. It should turn smoothly and uninhibited.

This communication code (C1203) will be set any time the check engine light comes on. The data link between the two computers becomes interrupted when there is a malfunction in the engine control computer or if the brake warning light is illuminated. The code itself is nothing to be worried about unless it won't clear and this is causing the lights for the VSC system to remain on. If this is the case then there is a problem in the communication line between the VSC computer and the engine control computer. This is extremely unlikely though. Remove the negative battery cable to erase all the memories in the on board systems then see if everything functions normally and this 1203 code disappears

Was there a security chip in the old key ? If there was, you have to get a new key cut to fit the new lock that matches the old chip.

You can do one thing, not sure if it would work, but try this: 1. Go to the drivers front door, 2. There should be a lock in the door, place the key in the lock. 3. Turn the key to one side or the other, by this time you should be able to hear a familiar sound, as when you unlock a door from the inside. Good luck.
