Battery Changing Instructions
Models 6120 and 6123 Using a Two-Battery Keypad
Step 5—Align the spring clips with the receptacles in the base.
Using steady pressure, push the keypad housing back onto
its mounting base. Don’t allow any wire(s) to be damaged by
contact with the spring clips. The keypad housing will snap into
place on the base.
Step 6—Check the master code and all user codes at least
three times with the safe door open. Close the safe door only
after the lock has been thoroughly checked to make sure it’s
operating properly.
Note: The 6120 and 6123 will operate with just one 9-volt
alkaline battery attached to either connector of the standard,
two-battery keypad. This is only recommended under
emergency conditions when a second replacement battery is
not available. Using a single battery will not harm the lock in
any way.
