Important: You must have the correct change key. Do not set the third number of the combination between 5 and 11 on a lock with a dial splined at 50. The “forbidden zone” can shift slightly due to installation and tolerances, but will always be between 4 and 12. Do not set adjacent numbers of the combination within five numbers of each other. Do not remove lock cover. If an error is made, re-dial the entire combination.

A U8 change key is required to change the combination. If you do not have a change key please contact your safe manufacturer or one of our distributors to purchase one.
