The patented Yale Security Cylinder (Patent No. 4638651)
contains two independent locking mechanisms. The first is a traditional 6 or 7 pin tumbler
mechanism with spool drivers for greatly increased picking resistance.
The second is an innovative 5 tumbler rotating disc
mechanism with sidebar engagement. The rotating discs are spring loaded and block the
bottom of the keyway. Only a specially cut key will move the discs and allow entrance of
the key. This key has special side biting and must align all five discs perfectly before
the cylinder plug will rotate to open the lock.
This cylinder is virtually pick proof, because the
unlocking mechanisms must be activated in two directions.
In addition to the mechanical security offered by these
cylinders, Yale provides a number of security controls. Only the "GST" and
''VYZ'' family of surety keyways are assigned to these cylinders.
