A commercial lock is heavy-duty hardware, cylindrical or mortise, built for doors that open hundreds of times a day. Ours carry ANSI/BHMA Grade 1, the highest commercial rating, tested to one million cycles. For 25 years King Locksmith and Doors Inc. has installed, repaired, replaced and rekeyed commercial locks across Maryland, Washington DC and Northern Virginia, licensed, insured and bonded.
Commercial locks use two chassis formats, the chassis being the metal body that does the work. Cylindrical locks sit in a 2-1/8 inch cross bore, the round hole through the door face, on a 2-3/4 inch backset, the distance from door edge to hole center. Mortise locks sit in a pocket cut into the door edge. Inside either, the retractor pulls the latch back when the lever turns.
Cylindrical bodies follow ANSI/BHMA A156.2 and mortise bodies A156.13, the standards behind Grade 1 testing. Cylinders come conventional, like a 6-pin SC1, or as interchangeable cores a control key swaps in seconds, no lock removal. Pick your format and we install it.
A commercial lock solves what a residential lock cannot: constant use. A house door opens a dozen times a day. A shop, clinic or office door opens hundreds, and Grade 1 hardware, rated for one million cycles, keeps the lever level and the latch crisp after a light-duty lock goes loose.
Standard door prep means a new commercial lock drops into existing holes without drilling. Interchangeable cores mean we rekey in minutes when a key walks off. Still running residential hardware? Upgrade before it fails.
Commercial locks run on storefronts, office suites, warehouses and school corridors across Northern Virginia, wherever heavy traffic meets keyed control. Storeroom function, where the outside lever stays locked and only a key opens it, dominates back-of-house doors; entrance function suits front doors staff lock and unlock.
A commercial lock is wrong on a bedroom or bathroom door, where a residential privacy lock fits, and on a fire exit that needs panic hardware. Not sure which fits? We survey it free.
Storeroom, entrance or office function, cylindrical or mortise: the right answer depends on who needs in and how often the door opens. Our locksmith surveys your doors, names the function each one needs and quotes the install on the spot, free.
Five commercial lock brands ride on our trucks because they survive busy doors: parts we stock, bodies that last, cylinders that fit your key system.
Schlage ND is Grade 1, the highest commercial rating, and the lock we quote most, so its levers, springs and latches ride on every truck.
Falcon T delivers Grade 1 strength at a lower price, so a multi-door installation stays on budget without dropping to Grade 2, the lighter rating.
Best 9K takes interchangeable cores, the keyed section a control key pulls in seconds, so we rekey a whole building without unbolting a single lock.
Corbin Russwin CL3300 sits on many older institutional doors, and we carry its trim and chassis parts, so a worn lock gets repaired, not replaced.
Three failures dominate our commercial lock calls. The latch stops retracting fully, so the door sticks shut: the retractor has worn, or the spindle behind the lever has bent. The cylinder spins in the lever: its retainer clip has let go. The lock rotates on the door: through-bolts have loosened or the cross bore is oversize.
Our locksmith checks door and strike alignment first, then chassis, then cylinder, since a rubbing door mimics a worn lock. Locked out? Mobile units respond 24/7. Call (240) 345-1455 in Maryland or (202) 800-2622 in Washington DC and NOVA.
Our trucks carry retractors, spindles, latches, retainer clips, through-bolt kits and spring cages, which keep levers level. Worn retractors and bent spindles swap inside the existing chassis. A spinning cylinder gets a new retainer. A rotating lock gets fresh through-bolts. Repair loses when the body is discontinued or attack-damaged.
Then we recommend replacement. We match function code, grade, backset, cylinder format and finish, so the new commercial lock drops into the existing prep without drilling, keyed to your master system where the keyway allows. Measure, match, install, then test operation and egress. Our in-house door expert fixes frame alignment the same visit. Estimates are free.
A commercial door that will not lock is lost revenue, not a chore for later. Call (202) 800-2622 now or book your installation online.
