The probable fault could be central locking activator passenger door

No, likely to be caused by the actuators in the lock mechanism failing usually causing the door to remain locked. The boor door can also fail this way, as do the front side doors. Replacement requires the whole lock unit to be replaced at a cost of roughly £60 a lock, and a hours work. Helps if you have small hands. Requires a full strip down of the door and you will need the lock unit, trim clips (a few quid) and a trim removal tool (tenner). You can bodge with a flat head screwdriver, but the tool does help prevent damage to the clips & trim panel.

SOURCE: passenger side door will only unlock if you pull handle and only lock if you push lock down.key,switch or remote won't work.

You are on the right track.

Door panel is easy to take off. you need a screwdriver and a panel popper (or if you don't have one carefully pull the panel off with your hands, you may have to get new panel clips) ,they are cheap so no big deal.
