What we need to work on an existing system
The master if you have it, change keys, and a list of doors. A bitting chart if a previous locksmith left one — rare, but gold.
If nobody knows the structure, the first visit is identification: what can be saved, what is already combinatorial chaos, and whether a rebuild is cheaper than chasing ghosts.
Small buildings vs campus systems
A three-door shop with a master and two change keys is a normal job. A multi-building campus with grand masters is a specification project. We will not oversell the first as the second.
Questions people actually ask
Can you add a door to our current master?
If the cylinder is compatible and there is room in the pinning to add it without collapsing the system, yes. If the system was already pinned into a corner, adding “one more door” can break other keys. That is why we look before we pin.
