Commercial Lock Types & Hardware Service in Washington, DC

Identify the commercial lock or cylinder architecture first, then connect it to the right repair, replacement, key-system or access-control service.

Need help identifying a commercial lock type in Washington, DC? Call (202) 559-7070. Commercial doors may use cylindrical, mortise, interconnected, deadbolt or removable-core hardware, and the correct service depends on the actual chassis, cylinder/core format, door preparation and function rather than the trim name alone.

Core Commercial Mechanical Lock Types

These hardware guides explain the physical lock architecture behind common commercial openings. Once the chassis and cylinder/core format are identified, the opening can be routed to repair, replacement, rekeying, master-key or access-control work as appropriate.

Specialized Commercial Hardware Families

Storefront, exit-device, access-control, high-security, gate and cabinet hardware each behave differently enough to need their own service path. Use these categories when the opening is more specialized than an ordinary cylindrical, lever, mortise or deadbolt lock.

Frequently Asked Questions

What is the difference between a commercial cylindrical lock and a mortise lock?

A cylindrical lock uses a bored chassis crossing the door, while a mortise lock uses a larger case installed into a pocket in the door edge. The prep, components and replacement considerations are different.

Are commercial lever locks always cylindrical locks?

No. Commercial lever trim can operate cylindrical, mortise, interconnected and electrified lock bodies. Identifying the chassis behind the lever is part of diagnosis.

What is an interchangeable core lock?

It is compatible lock hardware designed so an authorized control key can remove the keyed core without taking apart the whole lockset. SFIC and LFIC formats must match the host housing.

Do storefront hookbolts belong under commercial lock types?

Yes. Storefront hookbolts are commercial lock hardware, but their narrow-stile door preparation, keeper alignment and cylinder/cam relationship make Storefront Lock Repair the more useful service path for that opening.

Where should I start if I only know the symptom?
