After looking long and hard for an adequate safe for multiple pistols I own, I came across this safe by chance, and overall, it had everything I wanted. Other safes I was looking at were quite small, looked flimsy, and even though they featured biometric capability, the user reviews left me very unnerved - some being broken into by children, while others being broken into with a firm strike with a fist. I am sure such stories were rare, but the fact that such incidents occurred left me highly wary of making a purchase. Not only is this safe larger than most within this price category, but the door and (4) bolt locking system is very robust. I was very pleased to see how solid and well built everything looked, and the heft / weight of this safe leaves me feeling confident that my firearms will be kept safe from curious children. Some users mentioned the carpeted shelves being flimsy and easy to give way. Yes, the shelves are very basic, but I had no troubles securing them in place with several firearms worth of weight that did not cause them to tilt or break free. Further, they are adjustable, allowing you to place them in differing areas, based upon your storage preferences. The locking mechanism feels very robust and stout - you can feel the (4) heavy duty bolts locking firmly into place, and the door has a nice solid heft to it as well. As for the keypad, it was very easy to program, and is very easy to use with soft push button keypads that allow you to input a (5) numerical code - everything except "00000", which would be ludicrous to use. I prefer this numerical keypad style of entry versus biometrics, as the more I read about biometric access, the less certain I felt. I am sure there are some excellent biometric safes available, but I simply like the basic numerical entry - safe, simple & effective, especially if you need access without fuss & bother. One of the features I like about this is the fact that if an incorrect code is inputted more than (3) times over, the system will lock out for a full (2) minutes, which will discourage a curious or malicious person trying to crack your code. In terms of security, this safe can be bolted down to the floor, which is wise to do, if you have the means to do so. The included bolts are very heavy duty, and would be very effective in keeping anyone from removing this safe from your residence. Without the bolts (despite the 100+ lbs. weight of this safe), a malicious person could pick up this safe and walk away with it - demonstrated by the fact that our FedEx driver carried the safe into our home. Access can be made with the keypad code that you enter, or in the case of battery failure (or forgetting your access code), the safe comes with (2) skeleton style keys. What I like about the keys is the fact that the key entry is 100% hidden behind the removable keypad, which is not obvious at all. One would have to be knowledgeable about this feature to utilize it correctly, so I really like this hidden aspect. However, it is highly prudent such keys are hidden with great care, as curious minds could easily ascertain this information with a basic Google search. So, if you have young children or teenagers alike, be 100% sure this set of keys is in a locale they could never find - with them, access to the safe is moments away. One aspect that would be nice is interior LED lighting, as it is quite dark further back into the safe itself. However, you can easily find auto illuminating LED's for this very application, so this is an easy add-on to a well built safe. Overall, I am very happy with my purchase. I feel confident that this safe will vastly discourage anyone from gaining access to my firearms, and I trust that this layer of protection will keep my family safe, as I always want to be as responsible as possible when it comes to firearms - especially with curious children who simply do not know better, no matter how much they are taught or drilled. Whether your intent is to store firearms like me, or other valuable possessions, I feel that this Sentry Safe is one of the best on the market when you break down the size, pricing and features. I am very happy with my purchase, and look forward to utilizing this safe to its fullest potential. Review: Generally pleased with my purchase. There were some issues associated with it but no show stoppers. - The safe arrived early, kudos to the delivery personnel. Initially, they could not find the safe on their truck because side of the shipping box with the address label was face down and separated from the rest of the box. I presume this was a loading issue and some items may not have been secured for transport somewhere along the lengthy journey from China to Northeastern US. Generally pleased with the purchase. A few issues to highlight. The safe has about five or six scratches or bruises on the exterior; none major. Probably the result of handling. The safe was dusty inside and out. The left front shelf bracket was loose with two screws dislodged and unable to be firmly reinserted. I made a workaround. The safe must have been sitting in a warehouse for some while. There was some white powder material in various places inside the safe, probably from the insulation and (rough) handling again. Some of the interior covering material was loose. Likely, again related to repeat handling. Finally, the door handle is a little loose. Quality of product – A. Shipping and delivery – A-.

If there is a fire, is the key the knly way in?** A: The keypad is definitely not fireproof. It is nade of plastic. The way to go in is by key in case of fire. **Q: I want to store gold and silver. How much weight can each shelf hold?** A: I apologize for the late response but the shelves are able to hold 30 pounds in the center. SentrySafe stands behind the quality and workmanship of our products with a manufacturing warranty, after-fire replacement program (Fire-resistant safes), and a superior US based customer service team. For questions about our products, please contact us at 1-800-828-1438. **Q: Does this safe come with a key, just in case you forget the password?** A: Yes, this safe does come with override keys. **Q: I am thinking about offering these in my rooms that I rent out via AIRBNB - are the codes easy to set for new clients? I am trying to find the type that you normally see in a hotel. What do you think?** A: The codes are easy enough to set/reset on this safe. This safe, however, is WAY BIGGER than a hotel room safe, which is typically only big enough for jewelry, wallets, passports, tablets & phones. I love this safe as it holds 2 standard jewelry boxes of my stuff plus room for some file folders holding important documents. But then maybe the clients you rent to NEED a safe big enough to hold a laptop or brief of paperwork, etc. We LOVE this safe; our Police Dept. advised us to bolt it to the floor for added protection. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High Quality, Heavy Duty Safe *by L***Y on March 6, 2015* Excellent safe - very pleased with this purchase.

Condition of product – B. ### ⭐⭐⭐⭐⭐ High quality and spacious safe with one major (but correctable) design flaw *by A***A on June 16, 2020* I don't normally write product reviews, but felt compelled to review this safe. I own another (deposit style) safe from Sentrysafe and have been very happy with the overall build quality. I was looking for a slightly larger safe that offered more organization and usable space. This safe is very high quality, sturdy (and very heavy--100lbs). It has several very useful features including soft inner light, backup key access, and carpeted shelves. **If you read the reviews on this safe, I think most would agree on the superb materials, fit, and finish. Many of the negative reviews point to a flawed battery compartment design. The battery compartment for this safe is located on the INSIDE of the safe (as opposed to behind the keypad on the OUTSIDE of the door). This means that the safe needs to be OPEN to change the batteries. Unfortunately, there is a significant gap between the battery tray and lid so closing the heavy safe door can dislodge the batteries and disconnect the circuit, rendering the electronic keypad unusable and you will need to use the back-up key to manually open the safe. This completely defeats the purpose and convenience of the electronic keypad altogether. Some people have reported a few jerry-rigged solutions like inserting a piece of cardboard in between or taping the batteries in place. I had some extra furniture foam pads (the kind you stick under chair/sofa/table legs etc... (to prevent scratching hardwood floors) and stuck a few of them across the inside of the plastic lid cover. This eliminates the gap and secures the batteries in place when closing the safe door regardless of how (reasonably) hard I tried. Problem solved! I totally agree that this is a major technical fail in the engineering and design of an otherwise extremely high quality safe. I took a chance with this minor modification and couldn't be happier with the final quality and value of this safe! ## Frequently Bought Together - SentrySafe Fireproof and Waterproof XX-Large Black Steel Home Safe, DOJ-Certified with Digital Keypad Lock for Guns or Documents, 3.39 Cubic Feet, 27.8 x 21.7 x 19 Inches, EF3428E - SentrySafe Fire and Water Resistant Portable Bag with Zipper for Money or Document Storage, FBWLZ0SSC --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/44265199-fireproof-and-waterproof-xx-large-black-steel-home-safe-doj](https://www.desertcart.sn/products/44265199-fireproof-and-waterproof-xx-large-black-steel-home-safe-doj) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-10*
