Cannon Gun Safe. It will not stay locked. It will take my code and open but won't lock. The handle manually locks but will open without putting in code. I changed the battery and it did not help.

Hi,
First I would try the original numbers to see if you did change it. If the original numbers work then you need to start over. If they don't work then the new numbers you installed are there and you need to figure out what you punched in not what you meant to punch in.
Hope this Helps,

I had the exact same problem... All you have to do is unscrew a long, skinny, silver screw on the inside of the door. This unlocks the handle and locking mechanisms. Would have been nice if that step was in the instructions!!! Good luck.

(1) sounds like the interior lock activation screw is still installed. it's the long screw on the inside of the door with the yellow tag; (2) when entering the code, make sure the key is turned to the right; (3) after entering the code, make sure you next press the program button. enter the code wrong three times and it locks up for two minutes.
