Hi,
Very easy. Just buy a correct size and need only basic tools; level, screw
drivers, drill. I did it myself. I installed Lawson brand.
Wood core with Al clad.

Right Drill, hack saw, screwdriver, pencil, ruler is about it. Allow a few
hours for the job. Follow the instructions carefully and you will be just
fine. Many years ago I did this as a side job and could do a door in 30 to
40 minutes.
