How do I open a Gary Safe with dead batteries

Hello there,

You SHOULD have a mechanical key to open it in case of emergencies like this..
If you purchased it, you will have the key friend.

'The electronic lock provides security and easy access and it is equipped with a mechanical key for emergency access. The door is 9 Gage and the body is 14 Gage steel to resist break-ins.'

If it is lost, you need a locksmith.
