The CX-5 (or CX5) is a UL 437-rated pin-tumbler lock made by CX5 Security in South Korea. It uses six pin-tumblers and five springless sliders which interface with a sidebar. The CX-5 is functionally identical to the earlier ScanLock SLX-5 design.

The CX-5 is distributed (and sometimes rebranded) by a number of lock manufacturers, such as Marks USA in the United States. The CX-5 was originally sold by Scorpion and distributed by Can-Am Door Hardware, Inc. It has since been rebranded as "CX5" (no dash) by Far Pro Security Solutions and sold through CX5 Security of Canada/South Korea.

Principles of operation

The CX-5 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 sliders must be properly positioned to rotate the plug. The CX-5 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 frustrate 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 sliders of four possible depths, giving the CX-5 a total of 1024 (45) theoretical sidebar differs. Each slider 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 slider and properly positions their true gates. Slideers are left springless to promote longevity of the key track and the slider legs.[1]

  • Pin-tumbler bitting and sidebar track on the CX-5 key.

  • Key pins properly aligned at the shear line.

  • Sliders properly aligned.

  • Sliders misaligned.

Notes

  • Pin-tumbler bitting codes are designated 0 (0.339") to 9 (0.204"), jumping in incremenents of 0.015".

Disassembly instructions

The CX-5 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 sliders and sidebar will fall out of the plug.

  1. Remove the cam or C-clip.
  2. Insert the key and turn the plug 45-90 degrees.
  3. Withdraw the plug from the cylinder. (A plug follower is recommended)

OR

  1. Remove the chamber casings and take out each pin-stack individually
  2. Remove the cam or C-clip.
  3. Withdraw the plug from the cylinder.


Vulnerabilities

The CX-5 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.

  • Pins used in the Scorpion CX-5 version

  • Spooled driver pins

  • Steel sidebar

  • Sliders with false gates
