The following section applies to all models of Gun Vault gunsafes. Open the vault and lift the foam on the floor of the unit. There you will find a sticker with the serial number and key code.
Newer units have a key code stamped on the face of the key lock.
This is a low battery indicator and means that it is time to change the batteries. Call Gun Vault technical support and order a new key. Then change the batteries and reprogram your Gun Vault gunsafe. If you cannot find a key code, you will have to have a locksmith open the unit for you. You will then be able to obtain the key code from the sticker found on the floor of the unit under the foam.
