Access Methods
Your Grimtron Biometric Gun Safe offers four convenient ways to access your valuables:
- Password Entry: Enter your 3-8 digit password followed by the "#" key. The safe will unlock, and the knob can be turned clockwise to open the door.
- Biometric Fingerprint Scan: Place your registered finger on the biometric sensor. The sensor will illuminate, and upon successful recognition, the safe will unlock. Turn the knob clockwise to open.
- Emergency Key: In case of battery failure or forgotten password/fingerprint, slide the keyhole cover to the right, insert the emergency key, and turn it clockwise while turning the knob to open the safe.
- External Power (USB-C) with Password/Fingerprint: If batteries are completely depleted, connect a USB-C cable to the external power port. Then, use either your password or registered fingerprint to unlock the safe.
