What counts as commercial door hardware, and what usually goes wrong?
Commercial door hardware is everything that makes a business door open, close, latch, and lock: the mortise lock body or bored lockset, the lever or knob trim, the cylinder, the strike plate in the frame, the hinges, the door closer, and any exit device on the inside. These parts are built for far more cycles than a house lock, but a door at a shop, office, or warehouse can be used hundreds of times a day, and that wears things out in predictable ways.
Most calls we get fall into a few patterns. The door swings shut but the latch bolt doesn't catch. The key turns but the bolt doesn't move. The lever spins loosely and does nothing. The door locks fine in the morning and won't lock at night. Or someone forced the door once, and it has never closed properly since. Each of these has a different cause, and the cause decides whether the fix is a small adjustment or a new lock body.
This page is about repairing and replacing the hardware itself. If you are shut out of a business and just need to get in, that is a different job, covered under business lockout service. If the real issue is a broken glass storefront entry, the page on storefront lock repair goes deeper on that.
Why won't my commercial door latch or lock?
A commercial door that won't latch is almost never a mystery once someone looks at the edge of the door and the strike plate side by side. The common causes are mechanical and fairly easy to sort out in person. Here is what we check first, roughly in the order we see them:
- Strike misalignment. The latch bolt hits the wrong spot on the strike plate, or the strike opening has shifted from years of slamming. A small adjustment or a repositioned strike can fix it.
- Door sag. Worn hinges or loose hinge screws let the door drop, so the latch no longer lines up with the frame. The lock gets blamed, but the hinges are the problem.
- Door closer problems. A closer that is too weak won't pull the latch home, and one that is too strong makes the door slam and batter the strike. Adjusting or replacing it often solves a latching complaint.
- Worn or broken latch parts inside the lock. The spring in a mortise case can weaken or snap, leaving the latch bolt sluggish or stuck partway.
- Stripped or broken spindle and trim. The lever turns but the latch doesn't retract, because the square spindle has rounded off or the trim screws have loosened.
- Worn cylinder. The key sticks, turns hard, or turns freely without throwing the bolt. This can be a cylinder, a tailpiece, or a cam issue, and it is worth separating those before replacing anything.
- Swollen wood door or frame. On older wood doors, damp winter mornings can make the door rub and bind enough to keep it from latching, then it behaves again by afternoon.

Call (213) 577-1366How we handle a commercial door hardware call, step by step
We try to keep the process simple and honest, because a door that won't secure a business is a stressful thing to deal with. Here is how a typical call goes.
- You call (213) 577-1366. A person answers, any hour of any day. Tell us what the door does and doesn't do, what kind of door it is (wood, hollow metal, aluminum storefront), and whether it is currently secure.
- We help you make the door safe for the moment if needed. Sometimes that means telling you what not to force, such as a jammed latch, so a repairable lock doesn't become a broken one.
- A mobile van comes from our Westwood storefront, with the tools to inspect hinges, strikes, closers, and lock cases on site. We look at the door as a whole, not only at the lock.
- We identify the actual cause and tell you what we found, including whether a lighter repair is realistic or whether the part is worn out. You decide before we start work.
- We repair or replace the hardware, then check that the door closes on its own, latches without a push, locks and unlocks smoothly with the key, and unlocks from the inside as it should.
- We leave you with working keys, and we can talk through any follow-up, like rekeying so old keys stop working or a master key plan if you have several doors.
Repair or replace: how to decide
Commercial hardware is often worth repairing. A good mortise lock body can last decades, and the wearing parts, such as springs, cylinders, trim, and strikes, can often be swapped without replacing the whole case. If the door is otherwise sound and the lock is a standard type, repair is usually the more economical route.
Replacement makes more sense when the case is cracked or bent from a break-in attempt, the model is discontinued and parts can't be found, the lock has been patched several times, or the hardware no longer suits how the business uses the door. A shop that wants to move from a key to a keypad, for instance, may be better off with a new setup than another repair. Parts availability varies by manufacturer and age, and we won't claim a part is available until we have checked it.
One honest caution: if the door is fire-rated, it carries a label, and there are limits on how it can be cut or modified. We look for that label before changing anything. We also tell you plainly when a requested change isn't appropriate for the door you have, instead of making the cut and hoping.

Call (213) 577-1366What affects the cost of commercial door repair?
We don't quote numbers on a web page, because commercial door work varies too much for a figure to mean anything without seeing the door. What we can do is tell you what moves the cost up or down, so nothing surprises you.
The first factor is the type of hardware. A standard bored lockset is a different job from a mortise lock, and a mortise lock is different from an exit device with a rim cylinder. The second is whether it is a repair of a worn part or replacement of the whole lock case. The third is the door and frame material: hollow metal, wood, and aluminum storefront framing each limit what can be fitted and how much work is involved.
Other factors include whether the door has sagged and needs hinge or frame work, whether a closer needs replacing too, whether the keys must be reset to a new key pattern, how many doors are involved in one visit, and what time of day or night the call comes in, since an after-hours emergency is not the same as a scheduled visit. Distance matters a little too; Westmont is roughly 14 miles from our storefront. We'll explain how those factors apply to your door before work starts, and you can ask questions at any point.
- Type of hardware: bored lockset, mortise case, rim device, or electrified hardware
- Repair of worn parts versus replacing the full lock
- Door and frame material, and their condition
- Hinge, strike, or closer work needed to make the lock function
- Number of doors and whether keys need to match
- Scheduled visit versus an urgent or after-hours call
Office, warehouse, and storefront doors: what changes
The keywords are the same, but the doors aren't. An office door lock repair is often about a lever that has gone loose or a keyed entry that needs to match other doors in the suite. The hardware is usually a lighter-duty mortise or cylindrical lock on a wood or metal door, and the fix is often trim, spindle, or cylinder work. If your office has several tenants or staff groups sharing doors, a master key system may be a better long-term answer than cutting more copies.
Warehouse door lock repair leans toward rugged. Steel doors, heavy-use exits, hasps, and rim hardware take abuse from forklifts, carts, and constant traffic. We see frames bent just enough that the latch won't catch, and exit devices that stopped retracting properly. When the inside hardware is an exit device, our page on panic bar installation covers that side in detail.
Storefront doors are a third case. Aluminum frames with narrow stiles use specific lock types and specific strikes, and not every lock fits. A common cause of a front door that won't close properly is the closer, not the lock, which is why we also repair and adjust door closers as part of the same visit when it's the real culprit. If you want to move beyond keys altogether, access control installation is its own project, and we can talk it through with you.

Call (213) 577-1366Commercial door hardware in Westmont: what we see locally
Westmont is a densely built unincorporated area of Los Angeles County, with the ZIP codes 90044 and 90047. Business activity runs along the main corridors: Century Boulevard and Manchester Avenue for storefronts, and Vermont, Western, and Normandie avenues, where small commercial frontage sits alongside two-story apartment buildings. A storefront on the Vermont Avenue corridor or near the Vermont and Manchester intersection has a very different door than a shop tucked near the Jesse Owens park area, but the hardware wears in the same ways.
Storefront lock service along Century Boulevard and Manchester Avenue is one of the real local scenarios, and it ties directly to this page. A front door that is opened and shut all day develops a worn latch, a strike that no longer lines up, or a cylinder that sticks. Closing a business for the night and discovering the door won't lock is the call we hear most often. We can come out at any hour, and our mobile locksmith service is built for exactly that.
Climate plays a small role here. Westmont sits on a flat inland coastal plain with regular morning marine layer and mild temperatures. Corrosion is minor, so we don't usually see hardware eaten away by salt air. But damp winter mornings can swell older wood doors and frames, and a door that latched fine last week can start binding. In that case the lock may be perfectly healthy, and the fix is easing the door or adjusting the strike, not replacing hardware. We would rather tell you that than sell a lock you don't need.
The area's older buildings matter too. Many structures date to the 1920s through the 1940s, and some commercial doors in them are old wood doors with frames that have moved over decades. Security screen doors and window bars are widespread in Westmont, and where a business has an added security door in front of its main one, we check that both doors operate and lock together without the hardware fighting each other.

Call (213) 577-1366Before you call: a short checklist
A few details make the first phone call faster and the visit smoother. You don't need to know the technical names for anything; a plain description is enough. If you have a minute before calling, try to note the following, and then call (213) 577-1366 or use our contact page if you want to describe the problem in writing.
- What the door does: won't latch, won't lock, key sticks, lever spins, or door won't close
- When it started, and whether anything happened first, such as a break-in attempt, a slam, or a hard push
- The door material, and whether it is a single door, a pair, or a glass storefront door
- Whether the door is currently secure, or whether the building is open overnight
- Whether you want the keys changed at the same time
Frequently asked questions
Why does my commercial door close but not latch?
Usually the latch bolt isn't lining up with the strike plate, often because the door has sagged on worn hinges or the frame has shifted. A closer that is too weak can also stop the door short of latching. We check alignment, hinges, and the closer before replacing any lock parts.
Can you fix a commercial door that won't lock at night?
Yes, and we answer the phone around the clock for that reason. The cause might be a worn latch, a tired cylinder, a misaligned strike, or a broken spindle. We find which one it is, tell you what we found, and repair or replace the hardware so the door secures properly.
Do you repair mortise locks, or only replace them?
We repair them when it makes sense. Springs, cylinders, trim, and strikes can often be replaced without swapping the full lock case. If the case is cracked, bent from forced entry, or the model is discontinued, replacement is the realistic option, and we explain that before we start.
Do you handle office and warehouse doors, not just storefronts?
Yes. Office door lock repair and warehouse door lock repair are regular work for us. The hardware differs, from lighter mortise or cylindrical locks on office doors to heavy-duty steel doors and exit devices in warehouses, but the approach is the same: find the real cause first.
How much will commercial door hardware repair cost?
We don't give numbers without seeing the door. Cost depends on the hardware type, whether it is a repair or replacement, the door and frame material, whether hinges or a closer need work, how many doors are involved, and the time of the call. We walk you through those factors before work begins.
Can you work on a fire-rated door?
We check for the fire-rating label first. Labeled doors have limits on how they can be cut or changed, so not every modification is appropriate. We tell you plainly what can and can't be done to the door you have, instead of making a cut that causes a problem later.
Should I ask a locksmith for a license?
Yes. California requires locksmith companies to hold a BSIS LCO license, and it is reasonable to ask any locksmith for it before they start work on your business. Checking it takes a moment and is a simple way to protect yourself.
Can you rekey the doors when you fix the hardware?
Yes. If a lock is being repaired or replaced, it is a convenient time to change the keys so old copies stop working. We can also discuss keeping several doors on a matching plan. Tell us when you call so we can plan for it.
Will you come to Westmont at night or on weekends?
Yes. Our phone is answered 24 hours a day, 7 days a week, all year, at (213) 577-1366. Mobile vans run from our Westwood storefront, and we serve Westmont, including the 90044 and 90047 ZIP codes, along with the rest of our service area.
