Diosmio support FAQ

Common questions about manuals, registration, and support for this brand.

  • What should I do if I forget the code or the battery is depleted on my Diosmio safe?

    You can use the provided emergency key to open the door. Once opened, you can either replace the depleted batteries or press the reset button on the inside back of the door to set a new personal code.

  • Can I get a replacement if I lose the emergency key for my Diosmio safe?

    Yes, you can get a replacement key by verifying your identity and providing the serial number located on the safe's front lock hole to the manufacturer.

  • How do I stop the alarm beep after entering the wrong password three times in a row?

    To stop the continuous beeping alarm on your safe box, you must either enter the correct passcode on the keypad or temporarily remove the batteries from the safe.

  • Why is the green light turning on but my Diosmio safe still won't open?

    If you enter the correct password and the green light illuminates, but the knob will not turn to unlock the door, the internal batteries are likely too low on power to disengage the lock and need to be replaced.
