KAER 13-16 Gun Biometric Safe Review: Big Rifle Cabinet
The KAER 13-16 Gun Biometric Safe is a tall, wall-mount-style cabinet pitched at people with a real long-gun collection: the listing says it holds 13 to 16 rifles, including scoped AR-15 and M4 types, plus 4 to 8 handguns. It is a candidate if you want fingerprint access to a full-height cabinet and are happy to assemble and anchor it yourself. Skip it if you need a verified fire rating, a published weight, or a compact bedside box. This review is based on the listing, seller bullets and published specs, not on personal use of the product.
Bottom line
- Best for: a rifle-and-pistol collection in a closet, garage or spare room where a 55-inch-tall cabinet fits.
- Main trade-off: several headline numbers (rifle count, volume) are the seller’s claims, and no fire rating or weight is listed.
- Price: it sat in the $200 to $300 range at the time of writing, so check today’s price first.

Access and lock
The listing describes four ways in. The first is the fingerprint scanner, which the seller says opens in as little as a tenth of a second and stores up to 30 prints. The second is a digital PIN of 3 to 12 digits. The third is a pair of emergency keys. The text we could see cuts off before naming the fourth, but the included “battery box” suggests an external power route for a dead battery, so confirm that on the listing page. The speed and accuracy numbers are the manufacturer’s claims, not measurements we can verify.
Two behaviors are worth noting for a house with sleeping family members. A silent mode turns off the beeps for quiet retrieval at night, and an alarm function is said to engage a child-safety lock after repeated wrong attempts. That lockout idea is sensible: a cabinet that freezes after a string of failures is harder for a curious teenager to guess through. Ask what the reset procedure is, though, because a lockout that you cannot clear quickly is its own problem.
Whatever route you favor, plan the backup properly. Store the emergency keys away from the cabinet and out of children’s reach, and learn how the external-power option works before you need it. An unplanned battery failure at the wrong moment is the main practical risk for any electronic lock.
Build and security features
This is the part of the listing with the most specific claims. The seller says the body is cold-rolled steel with an anti-corrosion finish, a 14-gauge door and 22 mm solid locking bolts, with a reinforced anti-pry design. These are listing statements, and 14-gauge is a respectable thickness for a budget-tier cabinet, but the page does not cite any independent pry or burglary testing, and no fire rating appears in the details we have. Do not buy this as a fire safe. If protecting paper, hard drives or cash from heat matters, you would need a separate, rated container.
The listing also names a built-in anti-theft alarm. Alarms deter casual tampering, but a determined thief in an empty house is not much deterred by a beep. The anchoring is a bigger deal than the alarm: a tall, narrow cabinet is a tip-over and carry-off risk until it is secured to a wall or floor, so use the included hardware as designed and make sure whatever you fasten to is solid.
Interior and fit
The interior is the reason to look at this model. The listing mentions detachable shelves, modular gun racks, three movable mesh panels and adjustable triangular partitions, so the layout can shift between rifle racks and shelves for pistols, paperwork and accessories. A door organizer is also part of the pitch in the product material. The extra-tall interior is meant to give room for scoped rifles, and that is a real problem solver for AR-style rifles with optics.
Now the honest caution. The page states “11 cubic feet” as the capacity, yet the outside measurements of 15 x 20 x 55.12 inches work out to roughly 9.6 cubic feet before subtracting for the walls. That mismatch suggests the capacity figure is a rough marketing number, so do not rely on it. Likewise, 13 to 16 rifles in a cabinet only 20 inches wide depends heavily on rifle width, optics and how tightly they are packed; a loaded cabinet with scoped rifles will hold fewer than the headline. Treat the counts as a best case, measure your longest rifle with its optic, and ask in the listing questions how many full-size rifles people actually store.
No interior dimensions are listed in the material we reviewed, so check the images for them. Our best rifle safes and best gun cabinets guides explain how to measure for length, optic height and shelf depth.
Mounting and placement
The spec sheet lists a wall mount, and the seller says all the mounting accessories come in the box, each labeled, with an installation video available. A tall cabinet like this is assembled by the buyer, so set aside time, a helper and the right tools. Position it where you can anchor into solid framing or masonry, and avoid anywhere damp, since the listing’s anti-corrosion finish is not a substitute for a dry location. Closets, garages and spare rooms are the typical spots the seller mentions, along with the range.
The 55-inch height matters in practice. Check ceiling height, door width and the path from your car to the final spot, since a one-person carry into an upstairs room can be tough. The weight is not listed in the material we saw, which is a gap for planning a stairs move, so confirm it before ordering. Keep in mind that storage and child-access-prevention rules vary by state, so check the laws where you live.
Power and batteries
The lock is battery-powered, and the listing includes a battery box and emergency keys. It does not state the battery type, the expected life or how a low-battery warning behaves. Before relying on the cabinet, find out those details in the manual or the Q&A, and set a recurring reminder to replace the cells and to test every access method afterward.
If you run the silent mode, remember that the beep is also how many electronic locks tell you a code was accepted or wrong. Practice opening it with the sound off, in the dark, so you are comfortable with the cabinet’s feedback.
What owners say
No summary of owner feedback was available for this product at the time of writing, so we have no owner themes to share and will not invent any. When you read the listing’s questions and written feedback, look at these items:
- Assembly: how long it takes and whether any hardware was missing or confusing.
- Rifle capacity: what people actually fit, with and without optics.
- Fingerprint reader behavior: misreads, enrollment tips and the 30-print limit.
- Door fit and bolt engagement: smooth closing, alignment and noise.
- Seller support: replies to damage or missing-part reports.
Weight recent, detailed comments over short ones, and look for reports from people with long guns similar to yours.

How it compares
If you only need a few long guns, the smaller KAER 4-5 Gun Biometric Rifle Safe keeps the fingerprint reader in an 11-inch-deep cabinet listed for 4 to 5 rifles, and publishes interior dimensions. It takes less floor space and is easier to move.
If you prefer a keypad over a fingerprint reader, the KAER Electronic Long Gun Safe lists a 15-gauge body, 0.8-inch locking bolts, a battery box and pre-drilled holes for floor or wall mounting, with 3 to 5 rifles. It is a simpler lock for the same brand.
For handgun-only needs, the Vaultek 20 Series Biometric is a compact bedside box with pre-drilled mounting holes and a cable, and the Fort Knox PB1 Pistol Box is a mechanical, push-button pistol box in 10-gauge steel. Both serve a different job than a rifle cabinet. For a wider look, see our best gun safes under $300, the best gun safe overview and the gun safe reviews A to Z.

At the time of writing the KAER 13-16 sat in the $200 to $300 range. That can shift, so check today’s price on Amazon before deciding. For sale timing and how to avoid unverified codes, see the KAER 13-16 Gun Biometric Safe promo code page.
Final verdict
The KAER 13-16 Gun Biometric Safe is a large, flexible cabinet with fingerprint access and a thick-steel pitch at a mid-range price. It is attractive for a household with several long guns and a fixed spot to anchor it. Its weaknesses are the unverifiable headline numbers, the missing fire rating and weight, and the self-assembly. Measure your rifles, confirm the backup power route, anchor it solidly and keep keys away from children. Storage and child-access laws differ by state, so check yours.
KAER 13-16 Gun Biometric Safe FAQ
How many rifles will the KAER 13-16 really hold?
The seller says 13 to 16 rifles plus 4 to 8 handguns, but the cabinet is 20 inches wide. Scoped rifles take more room, so expect fewer in practice. Measure your longest rifle with its optic and check listing questions for real-world counts.
How do I get in if the battery dies?
The listing says two emergency keys come with it, and a battery box is among the included parts. Confirm exactly how the external power option works in the manual, and store the keys away from the cabinet and out of children’s reach.
Is it fire rated?
No fire rating appears in the listing details we reviewed. Treat it as a theft and child-access barrier only, and use a separately rated container for items that need heat protection.
Do I need to anchor it?
The spec sheet lists a wall mount and the seller says labeled mounting hardware is included. A tall, narrow cabinet should be secured to solid framing or masonry. Follow the manual and the installation video, and check local requirements.
How many fingerprints can it store?
The listing says up to 30 fingerprints, and a PIN of 3 to 12 digits is also supported. Enroll each finger at several angles, and keep the PIN and keys as backups in case the reader misreads.
