The CX5 is a UL 437 rated pin-tumbler lock made by [CYC] and distributed by CX5 Security Solutions Inc., Inc. It uses six pin-tumblers and five springless finger pins which interface with a sidebar. The CX5 is redistributed (and sometimes rebranded) by a number of smaller lock manufacturers such as Marks USA in the United States. The CX5 is functionally identical to the earlier Scanlock design.
Principles of operation
The CX5 uses six pin-tumblers and a sidebar as primary locking components. In function, it is similar to other sidebar-based pin-tumblers, particularly the ASSA Twin 6000 and the Mul-T-Lock MT5+. Both pin-tumblers and sidebar finger pins must be properly positioned to rotate the plug. The CX5 allows for ten pin-tumbler sizes, for a total of 1,000,000 (106) theoretical key differs. Given a MACS of 6, the real number of key differs is closer to 400,000 for any given sidebar bitting. Driver (top) pins are spooled to frustrated lockpicking attacks. The spool design is similar to those used in the ASSA Twin 6000.
The sidebar is made of steel and positioned at 9 o'clock in the plug. The sidebar interfaces with five finger pins of four possible depths, giving the CX5 a total of 1024 (45) theoretical sidebar differs. Each finger pin has one true gate and one false (shallow) gate. The key has a milled track on the left hand side that picks up the legs of each finger pins and properly positions their true gates. Finger pins are left springless to promote longevity of the key track and the finger pin legs.[1]

Notes
- Pin-tumbler bitting codes are designated 0 (0.339") to 9 (0.204"), jumping in incremenents of 0.015".
Disassembly instructions
The CX5 can be disassembled in the same way as a standard pin-tumbler lock. When a key is not inserted into the exposed plug the springless finger pins and sidebar will fall out of the plug.
- Remove the cam or C-clip.
- Insert the key and turn the plug 45-90 degrees.
- Withdraw the plug from the cylinder. (A plug follower is recommended)
OR
- Remove the chamber casings and take out each pin-stack individually
- Remove the cam or C-clip.
- Withdraw the plug from the cylinder.
Vulnerabilities
The CX5 may be vulnerable to one of more of the following:
Notes
- Key bumping is only possible given a bump key with the correct sidebar bitting.
