Key Control & Record Keeping
The TMK register logs all top master keys and control keys by system register number to prevent
d
uplication of systems.This type of register is kept by all manufacturers. Kaba maintains their
logs by keyway, parity pattern and system location.

Adding small & large format interchangeable cores to a system of conventional cylinders
Small format interchangeable core/large format interchangeable core cylinders can usually be added to a
system of 140 conventional cylinders at any time. KABA recommends that you write a control key for all
Peaks systems, so that if small format interchangeable core/large format interchangeable core is added later,
the control key will be properly designed.
Visual Key Control (VKC)
Visual key control is the marking of the face of cores and cylinders with the symbols of the standard key cod-
ing system. From a security standpoint this is not a wise practice. If a key is found, a glance at the face of
the cylinder would reveal what the key operates.
Do not stamp the plug face. This voids the warranty and may collapse the patent pin chamber.
Concealed Key Control (CKC)
Concealed key control is the marking of key symbols on the side or back of cores or cylinders. Kaba marks
the key symbol on the side of the core with a permanent marker. In this way, when the core is recombinated,
the key symbol can be buffed off and no damage will be done.
