Commercial Locksmith in Naperville and the Chicagoland Suburbs

Business doors take far more use than a front door at home, and a lock that fails is both a security problem and a lost-time problem. Our mobile commercial locksmiths work with business owners, property managers, facility managers and general contractors across the Chicagoland suburbs, from a single office door to a whole building.

Commercial locks and deadbolts

We install and repair commercial-grade locks built for heavy use, including mortise locks, cylindrical lever locks, rim and mortise cylinders, storefront locks, and heavy-duty commercial deadbolts for back doors, stockrooms and offices.

Master key systems

A master key system lets one key open every door while individual keys only open the doors they're meant to. We map your doors and who needs to get through them, plan the key levels, rekey or replace the cylinders, and cut and label the keys, leaving room to add doors and users later.

SFIC and LFIC interchangeable cores

Small format (SFIC) and large format (LFIC) interchangeable cores let you swap a lock's core with a control key instead of replacing or taking apart the lock. We install, rekey and replace interchangeable cores, which makes them a practical choice for buildings with frequent staff or tenant changes.

Panic bars, exit devices and door closers

We install and repair rim, mortise and vertical rod exit devices, and can add a keyed outside trim so staff can get in while the door stays locked to the public. We also adjust, repair and replace door closers that slam, drift open or stop latching. Exit doors are often covered by fire and building codes, so check with your local inspector or fire marshal on specific requirements.

Commercial door hardware and door repair

Hinges, strikes, pulls, push plates, flush bolts and kick plates all work together. We supply and fit commercial door hardware, and repair sagging, dragging or misaligned doors, including repairs after a break-in attempt, so the door hangs straight and latches every time.
