Frequently Asked Questions Cannon Safe Q&A

What do I do if I lost my combination?

Please make sure to call the dealer where the safe has been purchased. Give your serial number located on the safe (typically on the right hand side of the safe in top upper corner) to a store manager. They will contact us directly with regards to your combination. This is required for your security. NOTE: Combinations are only saved for maximum of 1 year.

Can I buy more keys?

We do not make keys here at Cannon Safe. You will need to contact a locksmith near you. You will need the key code number which is found on the small cylinder where the key goes into.

How do I reactivate my Silica Gel Dehumidifier?

When the indicating beads turn pink, the silica gel is becoming saturated and should be reactivated. To reactive, place the entire unit (do not disassemble) in 325 Fahrenheit oven for at least 3 hours. Let the unit cool enough to handle, then return to the safe. Note: the indicating beads will gradually turn blue again.

    How do I adjust my safe door?

    If your safe door has excessive in and out play that exceeds 1/8 inch, the door can be adjusted by using a Phillips screwdriver.

    • With the door open, locate the U-Shaped cutout on the rear of the left door jam that's in alignment with the second locking bolt from the top.

    • Using a Philips screwdriver, insert the end into the hole in the middle of the U-Shaped cutout.

    • Gently pull away from the safe in small increments to tighten.

      Use caution when adjusting. Over adjustment can cause a lock out.
