Master Key

A hierarchy. Each person gets a key that opens only their own door, while a master key opens a defined group of doors and a grand master opens everything. It gives a manager or owner access without handing out a ring of thirty keys.

Usually yes, if we can identify the keyway and reconstruct or obtain the existing key chart. Bring us a key and we will tell you what you are working with.

Use a patented restricted keyway. Blanks are not sold on the open market, and copies can only be cut with authorisation on file. It is the only approach that actually works.

Rekey the level that key opened, and any level above it. We can scope exactly which doors are affected from your key chart and do it with minimal disruption.
