I purchased two of these cabinets from this manufacturer. The cabinet comes locked so to use the it you must enter the key for the first time. After which you can insert the batteries. I opened the box, placed the key inside, turned it the correct way, and it is unable to turn back. The cabinet is now completely useless. I am just happy I didnt first drill it into the wall and get stuck unexpectedly days or months later. Let my experience be your warning to not risk anything as important as your keys in a cabinet that can break so easily.

Their customer support is non-existent. Go ahead, experience this for yourself and call 1-800-323-8181 and press for "customer support". Give them a test run on if they are going to be there for you the day everything breaks. You'll be left waiting until what I assume to be the end of time. I tried to reach that striking point by leaving my phone on speakerphone and doing some errands. I managed to complete all my errands and had to recharge my battery. I tried throughout the day. I am hold still as I am writing this review (after processing my return on Amazon).

I should have paid attention to an other reviewer who detailed how he had to dissemble everything to make it better. That was a red flag.

On a plus size, the metal is pretty thick, which I suppose can potentially be a minus because if your keys get stuck in this thing one day you are in for quite a horrible day.

Why did I give it 3 stars and not 1? Because I ordered two and the second one works. Also, there is no other option currently on Amazon for a wall key cabinet digital lock and I need one this moment so I'm stuck with having to take my chances.

I've always thought a key safe would be nice to have in our garage, so when I came across this electronic key cabinet, I decided it was time to get one!

The pros:
+ Killer deal, $79.45 when I bought mine & the shipping was free!
+ Nice sand color.
+ Electronic keypad entry.
+ High security manual override key, 2 keys are provided, in case the batteries fail.
+ Two 5/8" locking bolts.
+ Heavy-duty construction, 19.6 pounds!
+ Has built-in hangers for 48 keys.
+ Comes with lots of plastic key tags.
+ Comes with 4, AA batteries.
+ Wall hanging hardware is provided.

The cons:
- Membrane style keypad... don't like it. It feels funky & it's not designed for speedy code entry.
- The provided wall hanging hardware is too light for the 19.6 pound weight of this key safe. I upgraded to heavier hardware.
- The provided batteries were damaged. I upgraded to 4, AA lithium batteries.
- No padding or carpeting on the bottom of the key safe for items stored there. I installed a piece of indoor/outdoor carpeting that I happen to have.
- The door pull knob was mounted too high for our installation, so I had to move it under the control panel. I installed a small carriage bolt to cover the hole that was left when the knob was moved.
- The bolt knob didn't feel right... felt loose to me, so I took off the plastic back cover to investigate. To my surprise, the assembly work was VERY sloppy, looked like whatever hardware was at hand was used! What's spooky, is that it could have failed, leaving the key safe locked shut with no way to open it! I ended up rebuilding the bolt assembly with the correct thickness washers (shims), adding grease to make the movement operate more smoothly.

Like the size , and the weight makes it seem quite resilient to anyone who's in a hurry to steal your keys . I may have to order another for the garage . I recently had my truck stolen when someone left my residence so I decided to give this a try and mounted it in my mud room . My only concern is I hope the keyboard doesn't show wear to quickly .
Btw I used the maximum amount of numbers which is 5 . By using the first 5 numbers of my SIN it makes it pretty easy to remember . Very easy to set up to

This is my second one of this same model. I like the design. My first one broke - the electronic keypad quit-new batteries no help. So I ordered another one. This new one is built different - not as well as the older one? More plastic inside, cheaper door pull knob, and the rotating knob that locks/unlocks feels loosey-goosey. It's mushy and doesn't exude confidence in a locks. I'm disappointed in the quality. When this one breaks, I won't order another one of this model or make.

Works well. Easy battery replacement. Was easy to program. The keypad design could be improved but it definitely works!

My coworker ordered one as well and their battery kept on dying every month and then finally became unresponsive basically. He contacted the manufacturer and they are sending him a replacement - high five for standing by your product!

Very good for keeping spare keys, especially since I changed all the locks on my house to biometric. Dead battery? Go to this locked box (mount it in a hidden place OUTSIDE) that you can access. Hide it. I put mine behind a metal Texas Star on the back side of the barn...looks natural, easy access, hidden from view.
