Contact the store manager where you bought your safe if you lose the electronic code within the first year after purchasing it. The manager then contacts the manufacturer who provides the combination. If the unit is older than a year, some manufacturers do not retain the combination. Owners of older units need the master reset code. Using the code and appropriate procedure allows opening the safe and resetting the electronic code.
Requesting the electronic code or master reset code requires submitting the serial number of the unit to the manufacturer. Manufacturers often require proof of ownership before they supply the master reset code in order to maintain the security of the device. Working with the dealer, submitting the request through a local law enforcement officer, providing proof of purchase or sending a notarized letter of ownership are options. When submitting the request through the dealer or a law enforcement officer, the code is released to them and not the owner.
If owners are unable to contact the manufacturer, the other option is working through a locksmith. Sometimes the locksmith must drill through the existing lock, remove it and replace it with a new one. The process is often more expensive than replacing a cheap safe with a new one.
