Generic Homak Gun Cabinet Safe Keys Cut to Your Code - 2 HMC Keys With Black Covers, Fits Protex Gun Wall Safes

Why I tried these keys

I picked up a used Homak gun cabinet that was missing its keys. On the lock face was the familiar HMC prefix followed by a five-digit number—my lifeline for getting back into regular use without replacing the whole lock. Rather than hauling the cabinet to a locksmith or swapping the lock cylinder, I ordered two HMC replacement keys cut to that exact code. They arrived pre-cut and capped with black plastic heads, ready to go.

Ordering and setup

The ordering process is straightforward but unforgiving: you have to supply the exact key code. In my case, I double-checked the HMC prefix and each digit stamped on the lock face. I sent the code right after placing the order and received a confirmation that the keys would be cut to that number. No programming, no calibration, no additional fitting—the premise here is simple: that lock code equals that key profile.

A few practical notes from the process:
- The supported range is HMC17501 to HMC17750. If your number sits outside that span—or has a different prefix—don’t assume it’s compatible.
- Read the code directly off the lock face if possible; don’t rely on memory or paperwork.
- If your code has leading zeros or looks ambiguous due to wear, take a clear photo and confirm with the seller before they cut.

First impressions and build quality

Right out of the envelope, both keys looked cleanly cut. They’re standard metal blanks, each topped with a black plastic head. There’s no branding on the covers, which I prefer for a low-profile look. Cut edges were free of burrs, and the shoulder and tip alignment matched what I expect from a correctly coded key.

The black covers provide helpful grip, especially when you’re trying to turn a lock mounted in a narrow cabinet frame. The covers on my set were snug—no rattling or looseness. After a week of regular use, they didn’t shift or spin on the key blade. As for the metal, I can’t confirm the exact alloy, but the keys have the typical nickel-plated finish you’d expect in this category and show no early peening or deformation.

Fit and performance

Functionally, these keys behaved like originals. Insertion was smooth with no binding, and the lock turned cleanly without needing extra persuasion. I tested both keys multiple times; each engaged the lock consistently. There’s a specific “feel” you get with correctly cut code keys—consistent resistance and a clean stop—and that’s what I experienced.

One important caveat: if your cabinet’s lock is worn or has picked up grit over the years, even a perfectly cut key can feel sticky. A light application of a dry film or graphite lock lubricant can help. I tried a few turns before lubricating and then again after; both worked, but the action was appreciably smoother with a tiny bit of lube.

Ergonomics and everyday use

The black caps are the quiet upgrade here. Small heads can be a pain on cabinet locks—you’re often turning from an awkward angle, sometimes with gloves. The added surface area and texture make it easier to turn without strain. They also help with quick identification if you keep multiple small keys on one ring. There’s no color-coding by default, but a silver paint pen or label on one cap is an easy way to mark “primary” vs. “backup.”

The set includes two keys, which is the right number for most households: one for daily use and one to stash in a secure place. The second key is identical in performance, which you want in case the first goes missing.

Compatibility and limitations

These keys are purpose-built for Homak/Protex gun cabinets using HMC-series codes in the HMC17501–HMC17750 range. A few limitations worth highlighting:

• If your code sits outside that range or your lock uses a different code family, these won’t work.
• You need the exact code. If you don’t have it, you’ll be guessing—and a guess is an expensive way to end up with two pieces of scrap metal.
• These are mechanical keys only. They won’t add any security beyond what your cabinet’s lock already provides.

If you’re unsure, snap a photo of the lock face and confirm before buying. It takes a minute and saves a week of back-and-forth.

Security considerations

Gun cabinet wafer locks with code-cut keys are about convenience and access control, not high-security resistance. If you’re worried about someone copying a key from a code, remember the code is often printed on the lock face. That’s convenient for owners and potentially convenient for anyone who spots it. I recommend:
- Don’t share the code in photos or messages beyond what’s necessary with the key cutter.
- Store your spare key in a separate, secure location.
- If the cabinet is in a high-traffic area, consider covering or obscuring the code on the lock face once you have your keys.

If you require higher security, consider upgrading the cabinet lock to a higher-rated cylinder or pairing the cabinet with additional security measures.

Value

Ordering keys cut to code is almost always cheaper and faster than replacing the lock or paying for on-site locksmith service, especially for a wall-mounted cabinet. The inclusion of two keys and the simple “works out of the envelope” setup is the right fit for most use cases. Compared to rolling the dice at a big-box kiosk or grinding a generic blank to match a worn original, cutting to the factory code delivers better consistency and saves time.

Tips to get it right

• Confirm the prefix and number: HMC + five digits. Double-check each character.
• Verify the code range: HMC17501–HMC17750.
• Photograph the lock face in good light; keep the image in case there’s a question later.
• If the lock’s action feels rough, add a tiny bit of dry lubricant. Avoid oil that can gum up wafers over time.
• Label the spare and store it away from the cabinet location.

Where it could be better

There aren’t many moving parts in a product like this, but there are two areas that could improve the experience:
- Clearer up-front guidance on codes that fall outside the supported range would help prevent mistaken orders.
- Optional color-coded caps could make distinguishing between multiple cabinets or spares easier.

Neither is a dealbreaker, but both would cut down on confusion and time.

The bottom line

For owners of Homak/Protex gun cabinets with HMC-series locks in the supported range, these HMC replacement keys do exactly what they promise. My set arrived quickly, matched the code precisely, and worked without fuss. The black caps add welcome grip, the cutting quality is consistent, and having two identical keys offers peace of mind.

Recommendation: I recommend these keys if your lock’s code is within HMC17501–HMC17750 and you can confirm the exact number on the lock face. They offer a reliable, hassle-free way to restore access to a cabinet without replacing hardware or visiting a locksmith. If you can’t verify your code or your lock uses a different series, look elsewhere—code-cut keys are only as good as the numbers you supply.
