Doors are pretty straight forward. The steps in the Hayne's manual are sufficient for removing them. The trunk was the only one I found troublesome.
the trunk lock cylinder is the larger one in the third row next to the keys.
The cylinder is part of a larger unit which includes the latch and bolted inside the rear of the trunk lid. Unbolt the entire unit and remove it. See the little protrusion off the right side of the cylinder in the above picture? There is a locking pin inside that, which will prevent you from removing the old lock cylinder from the larger unit. You need to file the top off of that protrusion on the OLD lock cylinder (using a hand file or a grinding wheel). You'll work it down till you have a little shaft appear and you can shake the pin out. The old cylinder will then twist off of the latch unit. Put the NEW lock cylinder in its place and turn it until the pin locks it into place. Reinstall the unit into your trunk.
