Hidden in Wall Gun Cabinet With Hidden Keypad




I wanted to have a place to secure my firearms that wasn't visible all the time, so I came up with the idea of a recessed in the wall gun cabinet that doubles as a Full body mirror. Then I wanted to go one step further with a hidden keypad behind a picture to control a solenoid lock. 

ps. check out the video below for a quick look at almost final product.

Step 1: Find a Place, Buy Supplies

First thing you need to do is find a place suitable for a in the wall cabinet. You need to be careful of plumbing and wires.
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

The outside edge of the door is 2ft by 4ft so the hole in the wall needs to be smaller than that so that it is concealed by the door.
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

Run wires to the keypad, you may be able to go through the attic or under the house or in my case I pulled up floor molding to run the wires behind it to the keypad.

Step 4: Build a Box

Build a box out of the 1x4s to fit into the hole since the box is going to be slid out to the edge of the drywall there is going to be a 1/2 gap behind the box and the other side of the wall. I  attached plastic to the backside of the 1x4 frame for a back, but you could use paneling, thin plywood, etc. 

Slide (or pound in my case) the box into place and attach with screws.

Step 5:

Pick a place for the keypad , cut hole in wall and run wires to it .
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

I used 1x4's to make a 2' by 4' door.
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

Figure out a way to attach the solenoid, I used a small steel strap with holes in it to screw the solenoid to the door.(also used epoxy)
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

ok so the final product has been tweaked a little, the plexi with mirrored tint did not work out, so I replaced that with an actual glass mirror.

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.

    You got my vote, that is great, if everybody who owns guns had the mindset you have, we would be in a safer place and kids wouldn't be killing each other, it seems like everyday you see in the news where a toddler picked up a gun and either shot them selves or a playmate, great instructable.

    It is funny that I don't see stuff like that everyday. I think it is perception. The news likes to sensationalize everything to get ratings. Most gun owners are responsible and do keep their guns in safe locations. For context just think of the tens of millions of guns owned in this country. The math doesn't support the assumption that this stuff happens all the time. Please don't fall prey to that type of thinking.

    I've often thought of doing this my only concern is it's on an outside wall, this would make it susceptible to moisture from rainy or cold snowy weather, not so much in the form of leaks but more in condensation due to heat and cold, they also make in the wall safes and long gun cabinets out of metal that are reasonable to buy but you would have to hang a picture or mirror over them, nice job though this just shows what you can do for a few bucks and a little ingenuity.

    This is a great idea, I especially commend the clever idea of having the keypad 'off-site' in a sense, very, very cool.

    I just can't get your video to load for some reason. xD I'd really like to see it!

    it doesn't need to be heavy 14 or 16 is what I used ,and I think either on would still be overkill.

    1 do you remember of have a name of the solenoid and key pad you purchased. 2 is there any movement in the door with the latch.
