Where possible, Affinity Windows and Doors may be locked with the same key.
Two or more locks use the same key, so many locks can be used and only one key needs to be carried.
All cylinders may be operated by the same key (not to be confused with Master Keyed).

(adj.) Of or pertaining to two or more looks or cylinders which have or are to have the same combination. They may or may not be part of a keying system. Source: Lock Industry Standards and Training (LIST) Council
