(b) A side bar locking mechanism which integrally works with a rotating tumbler pin such that the side bar properly engages the tumbler pin with the correct angle (of three possible angles) when presented. Tumbler pins shall contain false grooves to provide additional resistence to manipulation. 2. All cylinders shall be designed and installed in locking devices, in such a way as to resist sharp forceful pulling forces intended to remove cylinders and expose the locking mechanism. 3. The lock pin tumblers shall combine a dual-axis action, with one axis utilized for pin tumbler rotation and the other axis utilized for positioning key cuts. 4. All cylinders shall be UL Listed Standard (UL437) for key locks. 5. The locking system is to be furnished in a restricted key section for which key blanks are not made available from the manufacturer's factory or any other source by normal distribution methods without proper authorization.

The cylinders shall incorporate a patented user rekeying features such as InstaKey (or equivalent) whereby the owner shall have the ability to immediately rekey a cylinder by inserting a using a new key in a designed sequence of keys and thus render a previously operating key useless. Such rekeying ability shall exist at all levels (user, master, grand master, and great grand master) applicable to a cylinder. Such rekeying to a particular level shall not affect the keying of the other levels. Once the pre-designed number of user changes at any level has been used up by the Owner, the Owner shall require the supplier to rekey the cylinder with another set of pre-designed user changes. 9.
