with power locks/windows you have to remove a few screws.
1) remove the one holding the window/lock panel and slide out. disconnect the power.
2) remove the one that is in the door hand-hold
3) remove the one in the upper corner of the panel (near where the mirrors are)
4) along the bottom of the panel, there are 3 or 4 screws attaching it. remove.
now take a screw driver or panel puller and pry the sides/ bottom off the door.
basically, you just lift it out and up, around the handle and lock. reverse to put back on
