Quick Attachment with Six N52 Magnets

Six N52 industrial-grade magnets help the lock attach quickly to suitable ferrous surfaces. The magnetic connection is convenient for vehicles, gun safes, metal cabinets, and other compatible storage locations.
Holding strength depends on the surface material, thickness, finish, contact area, and installation conditions.
The following figures are reference loads shown under specific test conditions:
- Non-metal surface reference load: Up to 8.8 lb (approximately 4 kg)
- Metal surface reference load: Up to 28.7 lb (approximately 13 kg)

Three Ways to Unlock

Choose the access method that fits your setup: fingerprint recognition, a 5-10 digit PIN code, or the backup key.
The lock supports up to 100 registered fingerprints, making it convenient for authorized household members or multiple users.

Adjustable Multi-Pin Design

Multiple steel pins allow the lock position to be adjusted around many trigger guard shapes. This flexible structure is designed for use with a wide range of handguns, rifles, and shotguns.
Firearms shown are examples only. Compatibility depends on the individual firearm's trigger guard shape, dimensions, and accessories.

Two Installation Options

  • Direct Magnetic Attachment

    Attach the lock directly to a suitable metal surface when quick, flexible placement is preferred.

  • Steel Mounting Plate Installation

    For non-magnetic surfaces, install the included steel mounting plate with the supplied wall anchors and screws, then attach the lock magnetically to the plate.
    Mounting Plate Size: 122.25 x 38 x 2 mm (4.81 x 1.50 x 0.08 in)

Designed for Everyday Use

Why isn’t my fingerprint being recognized?

Before adding fingerprints, please set a digital password first. Make sure your finger is clean and dry, as dirt, water, or worn fingerprints may affect recognition.

How many fingerprints can I register?

The Defender SE can store up to 50 fingerprints for authorized users.

What if the fingerprint or password does not unlock the device?

Use the physical backup key first. Then check whether the battery needs charging. If the issue continues, contact ONNAIS support at support@onnaisafe.com.

How long does the battery last?

The built-in battery lasts about 3–5 months in standby mode or approximately 2,000 unlocks. For best readiness, recharge every 2 months.

Can I turn off the sound?

Yes. Press and hold the Reset button for 3 seconds to mute operation sounds. Repeat the same step to turn sound back on.

What firearms does it fit?

The adaptive structure is designed to fit many handguns, rifles, and shotguns. Compatibility may vary by firearm model, trigger guard shape, and accessories.
