INSTRUCTIONS FOR FIELD KEYING OF LOST BALL CONSTRUCTION MASTER KEYING:

Creating a New Field Generated Master Key System Using the Lost Ball Feature

• . The lost ball feature can only be used in chambers 2 through 5. For XC cylinders use chambers 3 through 6
• Using the fixture, drill the plug of the cyfinder in two places in the location of the chamber selected for the construction feature . The construction balls (3) should be placed between the bottom pin and master split in the chamber selected for the
• construction feature . The chamber to be used for the lost ball feature is determined by the bitting selections in the Master Key System
• . The bitting of the Top Master Key (TMK) for the system must always contain a #8 cut between positions 2 through 5 for standard cylinders and 3 through 6 for XC
• The position on the TMK that was chosen for the #8 cut should always be used when generating change key bittings for the construction key system
• · Always use the change key to void the construction feature
• The Construction Master Keys (CMK) will have a #10 bitting cut in the same position as the TMK's #8 bitting, all other bittings will be the same as the TMK

Introducing the Lost Ball Feature Into an Existing Master Key System

• . If the existing master key system's TMK has a #8 cut in its bitting and the #10 cut has not been used for any key in that position, then the lost ball feature can be added to the system
• If the system is a Grand Master level or higher and the master level keys have been selected in this position, the lost ball feature would have to be voided by the master level keys instead of the change keys
• If the key system is existing and the TMK does not have a #8 bitting, contact the SARGENT Key Records department to determine if Construction Keying Mastering is feasible
