Commercial Door Hardware
Commercial Door Hardware Installation and Service in Longwood, FL
Door hardware is everything on a door that makes it open, close, lock, and let people out. On a commercial door, that includes the lock, the cylinder and key, the lever or pull, the hinges, the closer, and often an exit device. Each piece takes far more use than the hardware on a house door, and when one part wears out, the whole opening stops working the way it should. Lion Locksmith & Security installs, replaces, and services commercial door hardware for businesses and commercial properties in Longwood and across Seminole County. Commercial lock hardware is one of our core services, and our owner is a second-generation locksmith whose background as a contractor helps on door and frame work.
Commercial Door Hardware We Install and Service

Commercial door hardware we install and service (clockwise from top right): mortise lock, ADA-compliant door handle with lock, alarmed exit device, alarmed crash bar, double doors with crash bars and magnetic closers, keypad lock, and a commercial-grade door hinge.
- Mortise locks, which are heavy-duty locks set into a pocket in the door's edge
- Commercial lever locks and storefront door locks
- Cylinders, rim cylinders, and interchangeable cores (IC cores)
- Commercial door closers
- Panic bars and exit devices, plus battery-powered exit alarms
- Continuous hinges and weatherstripping
Interchangeable cores are worth a closer look for growing businesses. The keyed part of the lock comes out with a special control key and swaps in seconds, which makes changing keys after staff turnover far easier. Cores can also be set up as part of a master key system so each key opens only the doors it should.
What Separates Commercial Hardware From Residential Locks
Commercial locks are built for doors that open hundreds of times a day. The industry grading system rates hardware by strength and durability, with Grade 1 for heavy-duty commercial use, Grade 2 for lighter commercial and quality residential use, and Grade 3 for basic residential use. High-traffic exterior doors and main entrances should carry Grade 1 hardware. Commercial locks also come in more functions, which control how the outside lever behaves. A storeroom function stays locked from the outside, a classroom function is locked or unlocked with a key, and an office function locks with a button or turn on the inside.
Hardware for Wood, Hollow Metal, and Glass Doors
The right hardware depends on the door it goes on. Hollow metal doors and frames are common on back entrances and stairwells, wood doors are common inside offices, and aluminum and glass storefront doors face the street. Each door type takes different locks, closers, and hinges. We also repair and realign the doors and frames themselves through our commercial door repair service, since new hardware cannot fix a door that sags.
Codes, Accessibility, and the Florida Climate
Commercial door hardware has to work within local building and fire codes. Fire-rated doors need fire-rated components, and doors in public spaces need hardware that opens without tight grasping or twisting, which is why levers are so common, along with closers set to reasonable opening force. Florida's building code also sets wind-load standards for exterior door assemblies. Heat, humidity, and rain are hard on finishes and moving parts, so we point you toward hardware that holds up in this climate. Your local building official makes the final call on code questions.

Commercial Door Hardware FAQs
What are the different types of commercial door hardware?
The main categories are locks and cylinders, levers and pulls, hinges, closers, and exit devices. Many doors also have stops, weatherstripping, and kick plates. Each part has a job, and they all need to work together for the door to close, latch, and lock properly.
What is the hardware on a door called?
The full set of hardware on one door is often called the door hardware set or the opening. Individual parts include the lockset, cylinder, strike plate, hinges, closer, and exit device. A locksmith or door hardware supplier will usually ask for each of these by name when quoting a job.
What is the best commercial door lock?
For most busy exterior doors, a Grade 1 mortise lock or a Grade 1 cylindrical lever lock is the standard choice. The Builders Hardware Manufacturers Association grades hardware through independent testing, so look for that rating. The best lock for your door also depends on the door type, the lock function you need, and your key system.
What is the difference between a commercial and a residential lock?
Commercial locks are built from heavier materials and tested for far more cycles than residential locks. They also offer more lock functions and work with commercial key systems such as master keys and interchangeable cores. A residential lock on a busy commercial door usually wears out quickly.
How much does it cost to replace a lock on a commercial door?
The price depends on the lock type, the grade, and whether the door needs any modification to fit the new hardware. A cylinder swap costs far less than replacing a full mortise lock. Call us for a quote on your specific door.
Do you work on automatic or overhead doors?
No. Automatic sliding doors, powered operators, and overhead or roll-up doors are handled by specialized door companies. We work on manual swinging doors and their locks, closers, hinges, and exit devices. If your opening needs one of those other trades, we will let you know.
Do you offer maintenance agreements for door hardware?
Yes, we offer them case by case. Regular service can catch loose hinges, worn locks, and failing closers before they turn into emergency calls. Contact us with the number of doors and locations so we can discuss what fits your building.
Do you service commercial door hardware in Altamonte Springs?
Yes. Altamonte Springs borders Longwood, and businesses there are well within our reach. We also work with businesses throughout Seminole County and in communities north of Orlando. Tell us about your building and we will set up an estimate.
