Key blanks for the PKS are very difficult for retail establishments (such as Ace Hardware, K-Mart, Home Depot) to obtain thus making the PKS a more secure system.
These cores are masterkeyed, but without the individual operating keys. Included will be two control keys and ten masterkeys that operate ALL of the cores.
These cores are new, old stock and feature original Best pins (no colored pins). The core marks are side stamped.
Presently Best Access Systems lists these cores for more than $40 for one combinated core. Here is a chance to obtain original Best cores that were made in the USA.
