Mortise cylinders on formal doors
Dupont high-security work is usually a restricted mortise cylinder on a townhouse or office door. The door stays intact. The Metro and a garage are the arrival.
On this visit
Dupont mortise finishes are matched, not approximated with a shiny replacement that shouts. Keys are a written list. Consultants come off that list on a date you pick.
Frequent questions
We have consultants in and out. How should keys work?
Short list, signed, and a rule for when a consultant key is destroyed. We help you write that. We do not cut a handful of unmarked keys.
Can we see the keyway at the shop?
Yes. Adams Morgan is a short ride north.
