Principles of operation

This lock has a double circular lever one pack consisting of 9 code wheels and 2 driver wheels. The other pack engages with the cuts on the key, drives the code pack and a corresponding fence that will go into the true cuts and then allows the bolt to be moved into the open or closed positions. The key has 9 different cuts (1 passive cut called AB). Cuts 1-4 are on the A-side of the key. Cuts 5-8 are on the B-side of the key. No cut on side A is called A1. Deepest cut on side A is called AB. AB is a passive cut. An AB cut meant that the next active cut is B5-B8. There is a transport key which being a no-cut is all A1's. Only one side of the key is ever active in each cut position. Cuts on the opposite side of the key in these positions are only to make visual inspection harder.
