Step 1: Find a Place, Buy Supplies
I purchased the keypad for around $13.00 and the soleniod around $12.00 on amazon. The keypad even reads rfid tags that came with it. I also used three 8 ft 1x4's and two 8 ft 2x4's.
Step 2: Cut the Holes
Be careful cutting into the wall I used a cheap multi tool from harbor freight to cut the holes.
I had a stud in the way I had to cut out, I measured 1 1/2 " behind the drywall to cut the stud so that a 2x4 would fit behind the drywall on top of the cut out stud. you need to the frame out behind the drywall with the 2x4's see pictures.
If your concerned about removing or cutting any stud in the wall you can easily work around them I just didnt want one in the middle of my cabinet.
also there is plenty of room for 1/2" foam insulation behind the cabinet so I would recommend putting it there if your on an outside wall.
Step 3: Wires
Step 4: Build a Box
Slide (or pound in my case) the box into place and attach with screws.
I made a recessed box out of plastic on my vacuum former but you could make a small wood box to mount the keypad in.
Step 6: The Doors
using a table saw I cut a groove into the side of the 1x4 to hold the mirror then cut a 45 degree angle on the ends of the 1x4's then assembled . Then add cabinet hinges... see pics
Ok so my 45's didnt come out quite right I will be covering them with rosettes in the near future.
Put hinges on a picture frame to cover up the keypad. I also put a screw in the wall for a magnet thats on the back of the picture frame to attach to.
Step 7: The Lock
I could have attached the solenoid to the frame instead but it never crossed my mind until just now.( I might change it)
then figure out a way to have the solenoid to catch onto something. I used a metal pipe strap that I bent into the shape I needed then attached it to the door frame.
Wire it all up and test the wiring BEFORE closing the door.
Step 8: Almost Final Product
I covered the 4 corners of the door with rosettes because of my poor cutting.(I think I like it better that way anyway).
I also put a diode across the solenoid to take care of inductive kick.
so I say almost because I still have to put a piece of wood across the inside to hold the barrels of the rifle and a place to mount a pistol.
