Every square is one home in a hundred.
A restricted or patented keyway is one whose blanks are supplied only through the manufacturer's authorised channels, so duplication is controlled rather than available at an ordinary counter, though the exact authorisation step varies by program and is not always a signed letter. For a company with staff turnover, cleaners and contractors, it means the keys in circulation are far easier to track. It can be introduced during a rekey, on the exterior doors only or across the whole premises, and works alongside a key register.
Just the lock, and the door it is fitted to. A rekey works on the cylinder itself: the locksmith opens it, fits a new set of pins matched to a fresh key, and the old key stops working the moment that is done, whether or not it ever turns up again. Knowing roughly how the old key looked, cut on both edges, a chip on the head, a certain brand, can still help identify which cylinders in the house shared that key.
Yes. Bring the box, the template and the instructions, and tell the locksmith the model beforehand so the bore and backset can be checked against your door. If the kit turns out to need a larger hole or a different faceplate than the door has, the locksmith adapts the door or suggests a matching model. Hardware bought online sometimes arrives set for a different door thickness, which is a small adjustment on site.
Photographs of each lock from outside and inside, plus one of the door edge showing the latch plate and one of the strike on the frame, tell the locksmith most of what they need. Add the door thickness if you can measure it, whether the door is wood, steel or fibreglass, the finish you want to match, how many doors are involved and whether you want them all on one key.
