Grandmaster Keyed Suites

A Grandmaster keyed suite consists of two or more Master keyed suites (see section 5.4) with an over-riding Grandmaster key that will open all the locks within the Master keyed suites it contains.


The process is the same as before but this time there are three shear lines:


  • One for the Change key

  • One for the Master key

  • One for the Grandmaster key


As in the case of Keyed alike suites, the Kasp™ 125 series Premium Brass Padlocks can be both Master and Grandmaster keyed by our in-house locksmiths, or a skilled locksmith can make them up using the 125 series semi-assembled padlocks and pinning kit.
