Lockwood Twin


Effective security of your premises depends largely on control of access to keys. The Lockwood Twin high security restricted keying system achieves a very high level of key control while also providing increased physical security over basic restricted keying systems.


Each Lockwood Twin Key has a unique security feature, an extra set of bitting along the side of the blade, the side code, in addition to the usual top. The side code acts on side pins to line up with a side bar in the cylinder. Each key (or key set) also has a unique pattern of side grooves on the blade, forming the profile.

A key with the wrong Twin profile cannot even be inserted. A key with the wrong side code cannot release the side bar. For a key to open a lock, it must have the correct profile, side code and top code.
