Change Shelved Mode Combination
▶
For System 2000 Locks with a code level of 71, or greater, you may change the
Shelved Mode combination. You may change the default Factory Combination of 50-
25-50 to a new combination to be used while the lock is still in Shelved Mode. Once
you have changed the combination for the first time, you may want to change the
combination again to a different Shelved Mode combination. You can even change it
back to the Factory combination of 50-25-50.
Required Items: Change Key, Current Shelved Mode Combination
