Straight answers.

With Biolokk, yes. It adds 2.0mm per side inside the trigger guard, which keeps the pistol inside the holster envelope on all 22 platforms we have measured. Conventional trigger locks are too wide to holster, so they come off the moment you carry. Biolokk stays on: holstered, carried, and drawn.

Nothing locks you out. Biolokk is fail-open by design: if every circuit dies, you can still open your own lock through a mechanical release. A child still cannot. We chose that failure mode deliberately, because a safety device that can strand its owner in an emergency is not a safety device. A concealed mechanical release, reachable only with the included release tool, opens the lock without power.

No. Biolokk is a removable safety device that installs in the trigger guard of the pistol you already own. Nothing about your firearm changes: no modified trigger, no altered internals, no account, no network. Take it off and your pistol is exactly the gun it was before.

Under three-tenths of a second, worst case, across every temperature and battery state we have tested. The match runs the instant you grip, during the draw, so on a real defensive draw the lock is already open before your sights are up. Your fingerprint is matched on a sealed module inside the lock itself, so your prints never leave the device and are never transmitted anywhere.

Biolokk fits the most carried compact and duty platforms: Glock, SIG Sauer, Smith & Wesson M&P, Springfield Hellcat, Walther PDP, CZ P-10, FN 509, Beretta APX, HK, and Ruger. We have measured 22 platforms so far, and the reserve form carries the full current list.

Yes. The lock stores up to five fingerprints on its sealed module, so you can enroll your own and a trusted partner's. Adding a print requires the physical release tool and, once any print is enrolled, a match from a finger already on the lock. No one adds a fingerprint without both.

The twin doors seal the trigger well. A finger that is not enrolled cannot reach the trigger, and the lock does not open for a print it does not know. That is what it is built for: the accident, the impulse, and the curious hands. No device replaces safe storage habits, but this one stays on the gun.

No. The release is concealed and requires the included release tool. There is no visible keyway, no button sequence, and nothing to pry at, so it is not discoverable by a child. Keep the tool where you keep the other things a child must not have. See What happens if the battery dies?.

No, and we will not pretend it does. Biolokk is a safety device built against accidents, curious children, and impulsive moments, not against a determined thief with time and tools. If theft is your concern, use a safe. Biolokk covers the hours your pistol is out of one.

No. Biolokk has no radio, no app requirement, and no network connection of any kind. There is nothing to pair, nothing to update over the air, and nothing to intercept. Fingerprint matching happens on a sealed module inside the device, and your data never leaves it.

Nothing. No card, no payment, no deposit. Reserving puts you on the list for the founder run. We contact you before the first run ships, and you confirm or decline then. Until you confirm, you owe nothing.

The founder run goes to production when the reservation goal fills. We will not publish a date we cannot stand behind. What we promise instead: we confirm with you before anything ships, and nothing is charged before you say yes.

Yes, any time before you confirm. Nothing is charged, nothing ships, and one message takes you off the list.

Biolokk is veteran-founded and built in Austin, Texas. Our founder served seven years in the United States Army across two deployments and built Biolokk around what an unsecured weapon actually costs. It is designed by people who carry every day.
