Construction Keying
Falcon offers two different construction key systems depending on the size of and application within the project. Both systems
permit the installation and use of regular door locks during construction, yet completely preserve the security of the keying system
for the ultimate building owner. The Master, Grand Master and change keys are never with the locks during the construction phase
of a building. Only the “construction” keys are sent to the job site. Where the job permits, we will utilize the “Lost Pin System” as
our standard system for construction keying. Larger or more complicated jobs may require the use of our “Blockokey® System” for
construction keying.
“Disposable Construction” Interchangeable Cores
This newly designed disposable construction core (1408) is an inexpensive alternative to interior
keyed construction cores. This core should be used on interior door applications or where
security on a site is not a concern. No keys need to be issued. The disposable core is inserted
in the lever or knob and is operated by a thumb turn, which retracts the latch bolt. Please use
either brass or permanent construction cores on exterior doors or secured areas.
Locks with “Lost Pin System
Our “lost” pin construction key system consists of one construction pin and a shallow hole in the side of the plug.
Construction Key—KB566
When the “construction” key is used, the construction pin is
always in the cylinder plug, sitting on top of the bottom pin.
Master Key—KB578
When the Master key is inserted, the construction pin is
pushed up into the cylinder housing. As the Master key is
rotated to the right, the construction pin will drop into the
hole in the plug, thereby eliminating any future use of the
construction key.

Locks with Blockokey® Cylinders
All lock cylinders on a specic project are operable by a special “project key.” Duplicates of this key may be assigned by the building
contractor to workmen and subcontractors as required. No regular change keys or Master keys are needed on the job. This eliminates
the possibility of subsequent exposure from lost or stolen keys.
How to order locks with Blockokey® Cylinders
Blockokey® locksets are ordered by adding the word “Blockokey” after the balance of the ordering information.

MProject Key—KB531
Lock cylinder is operated by the
special “project key.” The last
two pins in the cylinder are held
inoperative by the key block.

MProject Key—KB531
The special “project key” is canceled out by
removal of the key block. A key block removal tool
is furnished with the Master keys for the locks.
Simply push the removal tool into the keyway, then
withdraw it to remove the block. Thereafter, the
“project key” will no longer operate the lock cylinder.

regular change key or Master key.
