SKD’s Used in a Master Key System
The symbol SKD is used to indicate combinations in a master key system that are never operated by a
master key. Typical uses are for securing personnel records, pharmacies, evidence rooms in police stations,
etc., where SKD combinations provide greater security.
The key symbols SKD1, SKD2 and SKD3 represent different bittings. If you have three locks keyed to SKD1,
you have a keyed alike group. It is for this reason that SKD does not mean single keyed different.
SKD sets are never master keyed; their combinations are derived outside of a master key system.
Non-master Keyed Cylinders—One Level of Keying
SKD is the standard symbol for one level of keying. Locks are either keyed-alike (KA) or keyed-
different (KD). To prevent key interchange or repetition of SKD's, a bitting list can be generated under a
selected parity pattern and the bittings crossed off the list as they are used.
Important Note:
Serious liability can arise by furnishing SKD’s for different End Users under the same control key. Although
this is convenient for servicing it is not an acceptable practice. Kaba treats SKD’s under a single control key
like a master key system.
Kaba Factory Bitting List Policy
A bitting list is a document showing all the key combinations used in a keying system. Possession of a bitting
list imposes a serious responsibility for the integrity of the system. For these reasons, Kaba contracts desig-
nate the bitting list to be the property of the Dealer.
Since a bitting list requires the time and labor of a qualified professional to generate, a nominal fee will be
charged for creating the list or for a transcript. This charge is in the factory price list.
Orders for bitting list transcripts are subject to the conditions of the specific key control contract
and distribution channel.
Dealers and End Users ordering factory master keyed product in their contracted keyway, automatically
receive a copy of the bitting list from Kaba. Requests for additional factory bittng list transcripts for End User
keyways require a completed Kaba order shipping form with a designated signature matching one of those
found on the Kaba key systems authorized signature registration form.
