Locksmithing/Cosmo Safe #TB 3E


The batteries have died, I unscrewed the two screws under the keypad but they seem to be holding the entire front (the keypad the knob, etc.   There is no "hole" for me to put in the overriding knob.   I know my combination.   Does the whole front section need to be "pried" off?

Hi Anne,

The only part that you should "need" to remove would be the small plate held on by two screws immediately below the keypad.   The emergency dial would fit into this space, and there should be a drive spindle to "plug" the dial into.   The dial should have two pins on its back side, which mate with the drive spindle.

I'm not sure what you are looking at or for, but if you don't find the dial spindle under the small rectangle plate, then I would recommend that you have a safe technician from a local safe company check it out for you.

The dialing sequence for the lock that should be on your container should be:

4 times right to the first number
3 times left to the second number
2 times right to the third number
1 time left until the dial stops (should be between 0-10)

NOTE:   Left is counter clockwise, Right is clockwise.   The mechanical combination is NOT going to be the same as the digital code.

Hope this helps
