Interchangeable Core Advantages
Interchangeable core (I/C) offers maximum exibility to the
building owner. Whenever a key is lost or stolen, locks can be
rekeyed quickly by non-locksmith personnel. All it takes is the
special CONTROL key. This key is used to remove and install all
cores in the system. Just go to the door, remove the old core and
install the new one with the control key. Security is regained in
seconds!
Falcon’s interchangeable cores and I/C locksets are compatible
with other small format interchangeable core (SFIC) products,
such as Best and Arrow. Use our locks with their cores and vice-
versa. In most cases Falcon can even furnish cores master keyed
into your existing Best or Arrow key system. Just include a copy
of your existing bitting list with the order.
Construction Cores
Interchangeable core jobs requiring construction keying are
furnished with temporary cores which are keyed alike to a
combination unrelated to the permanent system’s master key.
When the building is turned over to the owner, the permanent
cores are installed and the construction cores are returned to
Falcon Lock for credit.
Orders must include the name and address of the person to
whom the construction keys and permanent master and change
keys should be sent.
The ”A” keyway is standard for I/C products and will be supplied unless otherwise specied. Falcon
keyways shown here are equivalent to Best and Arrow I/C keyways of the same names.
Consult factory for restricted keyways not listed here.
When ordering locks or cores master keyed into existing Best, Arrow or other compatible I/C systems,
a copy of the bitting I list for the existing system is required with the order.

Falcon master keying uses the A2 System (depths 0 - 9)
standard. We can provide cores into competitors’ A4 (depths 0
- 5) key systems but we generate new A4 systems solely at the
A2, A3 and A4 Systems
discretion of our Key Systems Department. We do not support
the A3 System (Depths 0 - 6). However, any Falcon core can be
combinated to A3 specs in the eld.
