Lost both keys , and forgot the combination that I changed due to a person seeing me do it now I can't get in. What can I do!

A locksmith might be able to open it for a fee.

Some safes allow a battery to be connected by an external cable, but I don't know on your model.

An article suggest contacting the manufacturer using the phone number on their web site.

Hello, Richard -

Hi, Sorry to tell you only Bunker Hill will be able to sort this out. Please leave me feed back: Malcolm Campbell, Thanks.

Try a locksmith first. You may end up having to destroy the key lock to get it open.

Contact Harbor Freight Tools since they are a distributer of that product.

I’m happy to assist further over the phone at https://www.6ya.com/expert/kevin_c38b47f462e94458

To change the code: Your safe comes
preset with the default code of “159-A”.
To change the code, first open the safe.
On the inside of the door near the hinge,
there is a small red “reset” button. Press
this button until the Yellow LED on the
front panel lights up. Now, input your new
code up to 8 characters, followed by
either “A” or “B”. The Yellow LED will flash
to indicate that your new code has been
accepted. Warning: If the Yellow LED
does not flash, the code has not been
accepted, and you must start over.
NOTE: Be sure to test your new
combination before closing the door.
NOTE: Be sure to have the Override Key
available when setting a new
combination or changing batteries, in
case the door doesn’t open.

Good Luck
