How Four Quadrant Keys works

Call (771) 246-1201 Text us

Four Quadrant Keys connects people across DC's four quadrants with a locksmith; it is not one itself, and nobody here works on a lock. However you reach us, the request goes to a single independent locksmith business working inside the District. From there the business owns the callback, and if you say yes, the job.

Who pays us

Our fee comes from the locksmith business, for passing your request along. Nothing is charged to you by us. The business sets its own rates, and your invoice is between you and it alone.

The terms a business accepts to get DC requests from us

If a visit falls short of that list, text us at (771) 246-1201.

Why DC makes this harder

The District does not license locksmiths. Maryland licenses locksmith businesses and registers the people who work for them, and Virginia regulates locksmiths through its criminal justice services department. Inside DC, anyone with a general business license can advertise lock work. What you can still check.

Sources and data

Each guide closes with a list of what it relied on. The ward figures on our data page are our own work from Census tables and MPD incident counts, and the method page spells out each step. Read the method.

Who writes this

John Voll writes the guides. He has never worked as a locksmith; his job here is reading the price surveys and the District's own records, then naming the origin of each figure.
