sure its not that hard at all. and if youre just gonna fish back the lock lever you dont even have to pull the hole thing off.
remove the plastic that surrounds the chrome door pull there is a screw there. and ,this is from memory, there is another screw where the door catch is.
Im not sure if im confusing this with the front but at the bottom of the door handle there should be another screw (if not then its the front door that has it)
Then grab the bottom edge and pull away from the door. It will make pop'n snap sounds cuz the plastic plugs are pulling away. Dont worry if you break a couple, thats just the way it is.
And since youre just gonna put the lock lever back just reach in there and move it into place. its attached to another piece so its not a full bar or nothing, maybe less than 6" long.
