Biometric Gun Locks: Why B.O.S. Lock’s Biometric is Built Different

Aug 4, 2025

A common complaint about biometric gun locks is, “It never works when I need it to.” And that’s a problem. When it comes to securing a firearm, you can’t afford to second-guess whether your lock is going to recognize your fingerprint. You need it to work the first time every time. That’s why we built the B.O.S. Lock with higher-quality biometric technology, starting with our sensor.

The Problem with Most Biometric Locks

Most locks on the market use low-cost optical or basic capacitive sensors. These are the same types used in cheap electronics, not safety devices meant to secure a gun. Cheap biometrics are fooled and blocked; too often, they fail when hands are a little wet, dirty, or greasy. That’s not just frustrating. That’s dangerous. We knew from the start that if we were going to build something gun owners could trust, we’d have to do things differently.

Our Sensor Changes the Game

At the heart of the B.O.S. Lock is an industry-leading capacitive fingerprint sensor, but not the kind you’ve seen on discount safes. This is advanced biometric tech designed to read beneath the surface, capturing the tiny electrical signals between your fingerprint’s ridges and valleys. It is not fooled by sweat, oil, lotion, or the grime that builds up after a long day on the range or the other variables in everyday life that can throw off other biometrics. We built this for real life. We tested everything from sunscreen to gun cleaning solvents. We even sprayed our hands with PAM to see how far we could push it, and it still worked. Because in a moment of crisis, you won’t be thinking about whether your hands are clean. You’ll just need your firearm to be accessible and secure.

Designed by Gun Owners Who’ve Been Let Down Before

We didn’t build this out of theory. We built it out of frustration. We’ve used the other locks. We’ve felt disappointed when the sensor doesn’t read when we practice accessing our firearm. And we knew we could do better. So we started from scratch, with the sensor, the mechanics, and the entire system engineered for accuracy, speed, and reliability in real life’s messiness.

Precision Where It Counts

The B.O.S. Lock is:
  • Built with military-grade capacitive tech, not a budget scanner
  • Designed to recognize your fingerprint through sweat, oil, lotion, and more
  • Rigorously tested with everyday substances that throw off lesser locks
  • Fast, unlocking with your authorized touch in under a second
  • Selective, ignoring unauthorized prints

No More Guesswork

You don’t have to wonder if it’ll work. You don’t have to clean your hands before trying. And you definitely don’t have to deal with the frustration of false rejections when time matters most. The B.O.S. Lock gives you peace of mind that your firearm is both secure from the wrong hands and ready in yours. Because a lock is only helpful if it lets you in when it counts.
