DOM Plura

=DOM Plura=

The Plura is a pin-tumbler lock made by DOM. Its major advantage are the possibility to combine SKG** and SKG*** and no special tools are required to assemble the cylinders. The nickel silver keys are registered, allowing direct order by the number.

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. Chamber two contains a steel driver and key pin, the rest of pins is made of copper. The higher rated cylinder contains more steel pin pairs. Copper key pins are torpedo shaped, probably to act as an overset trap. The warding is relatively complex, but the keyway is not paracentric.

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.

Vulnerabilities
The DOM Plura is vulnerable to one or more of the following:


 * Lockpicking
 * Decoding
 * Key bumping
 * Impressioning
