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.

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.
EXAMPLE: 72 Each B511 D 626 1AA-72AA (Blockokey)
How Locks with Blockokey® Cylinders are Used
Project 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.
Removal Tool—KB536
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.
Change or Master Key—KB578
Cylinder is now only operable
by the regular change key or
Master key.
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.
consists of one construction pin and a shallow hole in the
side of the plug.
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.
