If your safe is not opening, it may be caused by:
Low battery
Incorrect combination entry
Make sure you are entering the correct combination.
β Two beeps or a green light = correct code.
β Single beep or three beeps = incorrect code.
Check the expiration date on the battery.
Use Duracell or Energizer 9V alkaline batteries with at least 5 years before expiration.
Do not use rechargeable, lithium, or off-brand batteries.
Try this physical reset technique:
Using a rubber mallet, gently tap around the keypad area (between the handle and keypad).
Turn the handle clockwise (to the right) and hold it down.
Lean your weight against the left side of the door.
Enter your combination.
As soon as you hear the double beep, turn the handle counterclockwise (to the left) to open the safe.
