There is no "default code", but they do keep the serial number and code on file, for just this purpose.

There is a small opening on the front number panel of safe. Use a small hex screwdriver or pin to insert into opening. It will open up the front panel (slide panel to right to take off) showing you 4 AA batteries. Just replace and close panel. Very simple to do. I wish the manual show me how. Instead of trying to figure it out for hours.

You must replace the batteries located in under the keypad.

Use a large paperclip to unlock the cover. Push the paperclip into the small hole while at the same time, sliding the battery cover to the right. Gently remove the battery housing and replace batteries. You will have to reset your password again, but can find the directions to do so by going to the Sentry site: http://www.sentrysafe.com/pdfs/OwnersManuals/172967.pdf,

I finally ignored the poorly-written instructions for programming a personal code and simply entered the factory code first and then pressed the prog/enter code button.  The safe opened.  The instructions tell you to push the prog/enter code first and then enter the factory code or personal code to open the safe.  Wrong!  Do it my way should this problem happen to you.
