Smart gun locks offer an alternative to a conventional key, but the right choice depends on what you need to secure. A trigger lock may suit a firearm in separate storage; a compact safe encloses the handgun and can help restrict access to the entire firearm.
These 10 picks span fingerprint locks, keypad-equipped models, wall-mounted options, and handgun safes. Use the comparisons below to narrow your options by fit, access method, and storage location.

- Holds up to four small handguns or three small-to-medium handguns, according to the manufacturer.
- App manages up to 40 fingerprints and shows unlocking records.
- LCD guidance, mute mode, and interior LED add convenience.
- Includes a security cable.
Cons:
- Its 13.39-by-9.84-inch footprint needs more space than a smaller handgun box.

Choose this model if storage capacity and guided setup matter more than minimizing the safe’s footprint. Check your firearms’ dimensions against the listed interior before buying.
Best Compact App-Enabled Safe – BILLCONCH B2 Handgun Safe
For buyers comparing smart gun locks for a drawer or nightstand, the BILLCONCH B2 offers a smaller handgun safe with fingerprint, numeric PIN, app, and key access.
Best For: One large or two standard-size handguns where a compact footprint and app-based fingerprint management are priorities.
Pros:
- Four unlocking methods provide alternatives if one method is inconvenient.
- App supports up to 40 fingerprints and displays unlocking records.
- Built-in LED helps illuminate the contents in low light.
- Listed exterior size is 10.82 by 8.66 by 2.75 inches.
Cons:
- Holds fewer handguns than the larger BILLCONCH model in this roundup.
- Arrives in Demo Mode, so setup is needed before regular use.
This is the space-conscious BILLCONCH option if you still want app controls. Confirm that your handgun and any accessories fit its stated interior dimensions.
Best for Multiple Fingerprint Users – Large Biometric Handgun Safe
This larger biometric safe stands out among smart gun locks when several authorized users or multiple enrolled fingers are needed: it stores up to 100 fingerprints and also opens by PIN or backup key.
Best For: Households seeking generous fingerprint capacity, a padded handgun compartment, and an emergency power option.
Pros:
- Stores up to 100 fingerprints.
- Accommodates one large, two standard-size, or three small pistols, according to the listing.
- USB-C port provides temporary external power if the AA batteries are depleted.
- Includes an interior light, silent mode, security cable, and mounting screws.
Cons:
- No app access is listed.
- At 8.8 pounds and 12.5 by 10.5 by 3.3 inches, it may be less convenient for tight spaces.
The fingerprint capacity and emergency power port are the main reasons to choose it. Measure the intended storage spot and your firearms before ordering.
Best Wall-Mounted Trigger Lock – ONNAIS Biometric Gun Lock
Unlike the enclosed safes in this smart gun locks roundup, the ONNAIS combines a biometric trigger lock with a wall-mounted firearm hook. It is intended for accessible wall storage rather than concealing a firearm inside a box.
Best For: Wall-mounting a compatible rifle, shotgun, or pistol with biometric-controlled trigger access.
Pros:
- Stores up to 50 fingerprints and offers three unlocking methods.
- Mounting options include wood, brick, metal, pegboards, and Slatwall panels.
- Aluminum construction includes rubber padding to help prevent scratches and slipping.
Cons:
- Does not enclose or hide the firearm like a handgun safe.
- Requires installation on a suitable mounting surface.
Consider this model when wall placement is the goal, but check firearm fit and plan the mounting location carefully. Its open-hook design serves a different storage need from the lockboxes above.
Most Fingerprint Slots – ONNAIS Defender SE
Among smart gun locks, the ONNAIS Defender SE stands out for storing up to 100 fingerprints. Its 360-degree scanner is advertised to release the trigger lock within 0.5 seconds, while rubber pads help protect a firearm’s finish.

- Compact design is intended for handguns, rifles, and shotguns.
- Rubber padding helps reduce scratches during installation.
Cons:
- The manufacturer warns not to use it on a loaded firearm.
- Over-tightening may scratch the firearm; some looseness after installation is normal.
Choose this model if a large fingerprint capacity matters more than a backup-key option. Check the fit on your specific firearm and follow the manufacturer’s unloaded-firearm warning.
Best With Backup Keys – Bison Fingerprint Trigger Lock
The Bison is a smart gun lock for buyers who want fingerprint access without relying on it exclusively. It stores up to 10 fingerprints, includes backup keys, and is advertised to unlock in 0.3 seconds with its 360-degree scanner.

- Soft rubber padding helps protect the firearm’s finish.
Cons:
- The 10-fingerprint limit may not suit larger groups.
- The manufacturer cautions against over-tightening and says to unload the firearm before use.
This is a practical pick when backup-key access is a priority. Confirm the fit on your firearm rather than assuming the adaptive design will fit every model.
Weather-Resistant Pick – Rechargeable Zinc-Alloy Trigger Lock
For smart gun locks that may travel in a range bag, this zinc-alloy model offers IP66-rated weather resistance and USB-C charging. It supports one administrator fingerprint and 49 member fingerprints, with two included keys as another way to unlock it.

Pros:
- Fingerprint unlocking plus two included backup keys.
- IP66-rated housing and USB-C charging.
- Supports up to 50 fingerprints, including one administrator.

The weather rating and charging setup distinguish this lock, but check its dimensions against your firearm before buying. Keep the backup keys accessible to authorized users.
Best Multi-Pistol Storage – Billconch Smart Gun Safe
For shoppers comparing smart gun locks with enclosed storage, this Billconch safe holds up to four pistols and offers fingerprint, PIN, app, or key access. Its pistol brackets and removable shelf help organize firearms and other valuables.

Best Key-Backup Trigger Lock – KENRONE Biometric Trigger Lock
Among portable smart gun locks, the KENRONE KR-TL69B pairs fingerprint access with two mechanical backup keys. Its zinc-alloy body fits over standard trigger guards on compatible handguns and many common rifles.
Best For: Owners who want a compact biometric trigger lock with key backup.
Pros:
- Stores up to 50 fingerprints, including an administrator profile.
- Includes two keys and a Type-C charging cable.
- Compact design avoids a bulky storage box.
Cons:

- Ships in a test state where any fingerprint can open it; enroll authorized prints before use.
This is a practical pick when a fitted trigger lock is preferable to a safe. Check compatibility with your firearm, and follow the manufacturer’s instruction to use it only on an unloaded firearm.
Best Keypad-Backup Trigger Lock – Biometric Gun Trigger Lock
If you are shopping for smart gun locks and prefer a passcode option alongside fingerprint access, this trigger lock adds a backlit PIN keypad. Its zinc-alloy housing is designed for the trigger guards of most handguns, rifles, and revolvers.

- Backlit keypad provides another entry method.
- USB rechargeable, with a low-battery indicator and emergency USB power port.
Cons:
- Confirm trigger-guard fit before buying; the claimed broad compatibility does not specify individual models.
- A trigger lock does not provide enclosed storage for the firearm.
The keypad makes this model worth considering if you do not want to rely on fingerprint recognition alone. Its included mechanical keys add another backup method.
How We Picked These Smart Gun Locks
We organized the 10 selected products by what they secure: a firearm’s trigger area or the entire handgun inside a safe. We also considered the access methods listed for each model, including fingerprints, PINs, apps, and backup keys, along with practical features such as mounting, internal lighting, and silent mode. Those features are useful comparison points, not proof of faster access or stronger security. Check current manufacturer specifications and independent certification claims before buying.
Quick Comparison: Trigger Lock or Handgun Safe?
Biometric trigger locks are the compact option. The ONNAIS, Bison, and other trigger-lock models in this roundup focus on blocking trigger access, with some adding a PIN or key backup. They do not enclose the firearm or necessarily prevent someone from handling or taking it.
Handgun safes provide an enclosure and may offer room for a pistol and small accessories. The BILLCONCH models and the larger biometric safe are better starting points if you want a contained storage space. Compare usable interior dimensions—not just the number of pistols in a product name—and confirm that your specific firearm fits.
Key Buying Factors for Smart Gun Locks
Fit, Placement, and Mounting
For a trigger lock, check compatibility with the firearm’s trigger guard and controls; do not assume a lock labeled for pistols, rifles, and shotguns fits every model. For a safe, measure the handgun with any mounted optic or light. Decide where the device will live, and follow the manufacturer’s mounting instructions. A cable or wall mount has a different purpose from a securely anchored safe.
Access and Backup Methods
Fingerprint entry can be convenient, but registration quality and finger condition may affect recognition. A PIN or physical key offers another way in if biometric access fails. If an app is part of the system, check which functions require a phone, connectivity, or an account. Practice opening the device under ordinary conditions rather than relying on a stated unlock-time claim.
Power, Security, and Compliance
Find out how the device signals low battery and how backup access works when power is depleted. Look for clear information about construction and resistance to tampering, but avoid treating a feature list as a security rating. Verify any advertised approval for the exact model and check your local storage laws; a compliant trigger lock in one jurisdiction may not meet another jurisdiction’s requirements. Never install a trigger lock on a loaded firearm unless its manufacturer explicitly permits that use.
Who Should Buy Which Smart Gun Locks?
Choose a trigger lock if you need a compact access barrier for a compatible firearm and already have an appropriate place to store it. Choose a handgun safe if enclosing the pistol is the priority, especially where other people could encounter it. Consider a wall-mounted model when a fixed location matters, or a PIN-and-key backup when you want alternatives to fingerprint entry. Whichever format you choose, confirm fit and legal requirements before purchase and follow safe firearm-storage practices.
