Inserts 34C may be retained in slots 346 formed in the lock shell 310.
It is a particular feature of the present invention that the provision of protrusions 334 on hive 322 requires that the key blank used to form a key suitable for use with the cylinder should be configured to have corresponding grooved recesses thereon. Since such grooved recesses cannot be formed by conventional key cutting apparatus, they must be present in the key blank produced by a manufacturer.
This arrancement allows the manufacturer the possibility of controlling a relatively large number of different key blank configurations. The provision of multiple elements having inner facing protrusions communicating with the interior of bore enables key mastering to be carried out in a convenuent manner. It also can be used to limit angular rotation of the key.
