The Sigma is a pin-tumbler lock made by DOM. It combines six pins in the standard configuration with up to 12 passive pins. The Sigma key profile is shaped to resemble the letters D O M.


Principles of operation

See also: Pin-Tumbler (Principles of Operation)

The lock contains six pin stacks - two chambers contain spooled drivers, the rest are tapered barrels. Keypins are standard, with a single exception being a torpedo-shaped pin.

Disassembly instructions

To disassemble a double euro cylinder, use of a pinning shoe is the preferred method.

Other possibility is to use a segmented follower, but that requires that both cores are pulled out a bit to allow a cam removal. Then a core should be rotated to approximately 4:30 or 7:30 o'clock position (135 degrees either clockwise or anti-clockwise) to prevent driver entering a gaps for the cam clutch. Then a segmented follower can be used to remove the core.
