HOW BLOCKOKEY CYLINDERS
ARE USED
1. Project Key Ð KB531
Operation of the lock cylinder is by the special “project
key.” The last two pins in the cylinder are inoperative
because of the “key block” mechanism.
2. Removal Tool Ð KB536
The “project key” no longer operates the cylinder
when the “key block” mechanism is removed. A key
block removal tool comes with the master keys for the
locks. Push the removal tool into the keyway and then
withdraw it to remove the block. Thereafter the project
key will no longer operate the lock cylinder.
3. Change or Master Keys Ð KB578
Cylinder is now only operable by the regular change key
or master key.
HOW TO ORDER LOCKS WITH
BLOCKOKEY SYSTEM
Blockokey locksets are ordered by adding the
word “Blockokey” after the balance of the ordering
information and are only available in Falcon keyways.
