KeyMark X4 Small Format Interchangeable Cores (SFIC) provide utility patented key control for applications that don't require a UL listed cylinder. Designed to allow the user to instantaneously remove and replace cores through the use of a control key, KeyMark cores provide the ultimate in convenience. The cores supplied are 7-Pin Cores
Each Keymark X4 comes with 2 keys. You will be given the option of ordering additional keys at checkout.
KeyMark X4 SFIC Cores:
Cylinders can quickly and easily be changed by non-technical personnel using a special control key which will remove the core from the lock housing. A core with a new combination can then be inserted and the lock will then effectively be "re-keyed". All of this can be done without having to take the lock apart which reduces the expense of calling outside service personnel to perform routine lock "re-keys".
Solid brass construction for excellent durability
Spool shaped top and bottom pins add a measure of pick resistance
Solid nickel silver bottom pins increase wear resistance
Individual pin chamber caps provide for ease of servicing
Locks can be keyed alike, keyed different, or master keyed depending on your specific needs
