For the front, right side, closest cylinder.

are you saying the front door does'nt lock with the central locking ? if so then the cental locking is usually controlled by the drivers door lock that sends signal to the othe door locks so depending which front door it is that will be the place to start , at least you know the alarm works

had a similar problem with a hyundai coupe , this turned out to to be the door lock mechanism in the drivers door, so could be the place to start, as i would have thought that generally the power locking technology is the same universally

switches inside doors are sticking wd-40 works just spray alot on and they will come free

problems with 3 out of 4 doors? Has your vehicle been in an accident just before these problem started? Cavaliers are known for problems but I have never heard of this type of situation unless the vehicle has been in an accident and the body wasn't realigned properly or verified.

Typically when you get a door that opens from one handle and not the other the problem is inside the door and part of the latch assembly has either broken or come apart. To fix it you have to open up the door itself and get to those controls.

The reason I asked about the vehicle being in an accident is because you described the door opening on it's own. Now that could have been because it didn't catch correctly but with all the other problems you mentioned I am concerned that the doors are out of aligned.

check lock buttons on doors and keyfob for stuck button

Have you tried to open it from the back seat? If you have then you will have to take off the cover on the door and there should be a release button. Most covers are easily removed with a flat head screw driver - If your door requires a motor to operate than that is your problem. Hope this helps.
