Why won't my commercial door latch or lock?
A commercial door that will not latch or will not lock is rarely a mystery once someone looks at it closely. It is usually one of a short list of causes: a latch bolt that no longer retracts or extends cleanly, a strike plate that has drifted out of line with the bolt, a worn mortise lock body, a door that has sagged on its hinges, or a closer that no longer pulls the door all the way into the frame.
The trouble is that these causes look identical from the outside. The door bounces back open, the key turns but nothing catches, or the handle feels loose and gritty. In an office, that means a suite you cannot secure at night. In a warehouse, it often means a chair or a stack of boxes against the door until somebody sorts it out, and that is not security.
Commercial doors also work harder than residential ones. A shop front or a medical office door can cycle many times a day, every day, so wear shows up faster and in more places. Springs tire, set screws back out, and the little parts inside a mortise case wear until the latch hangs up. We diagnose first and then repair what is actually failing, instead of swapping hardware by default.
What commercial door hardware do we repair?
Most of our commercial door repair calls fall into a handful of hardware families. Each fails in its own way, and knowing which one you have is half the diagnosis.
If your door has hardware that is not on this list, describe it when you call or send a photo. Odd or older hardware is common in commercial buildings, and we would rather know before the van is loaded.
- Mortise locks: the rectangular lock body set into the edge of the door. Common on storefronts and older office doors. They are repairable in many cases, and parts can be a deciding factor.
- Cylindrical and tubular locksets: the knob or lever sets found on interior offices, restrooms, and storerooms. These are often the lighter-cost fix when they fail.
- Rim-mounted and surface hardware: common on back doors, warehouse doors, and some metal doors.
- Latches and strikes: the bolt itself, the strike plate it catches in, and the alignment between the two.
- Exit devices: push bars and crash bars on doors that serve as exits. Our panic bar installation page covers new and replacement devices in more detail.
- Hinges, pivots, and door closers: not locks, but they decide whether a lock can work at all. If the closer is the real culprit, our door closer repair page explains that side of it.

Call (213) 577-1366How do we fix a commercial door that won't latch, step by step?
We work in the same order every time, because skipping straight to a part swap is how businesses end up paying for hardware they did not need. Here is how a typical visit goes.
- You call (213) 577-1366, any hour. We ask what the door does, what kind of door it is, and whether it is currently secure or standing open.
- If the building is open and cannot be locked, we treat that as the priority and talk through a temporary way to secure it while the van is on its way.
- On arrival, we watch the door operate before touching anything. Does the latch retract fully? Does the bolt line up with the strike? Does the door hang square or drag?
- We check the usual suspects in order: door alignment and hinges, the strike plate position, the closer, then the lock body or latch mechanism itself.
- We explain what we found in plain terms and lay out the options, usually a repair and a replacement, with the trade-offs of each.
- Once you approve the work, we carry it out: adjusting, re-aligning, rebuilding, or replacing the hardware as needed.
- We test the door repeatedly, with the key and with the handle, closed firmly and closed lightly, and confirm it holds before we leave.
Repair or replace: how do we decide?
Honest answer: it depends on what failed and how much life the hardware has left. A strike plate that is half an inch out of line is an adjustment, not a new lock. A mortise case with a broken internal spring may be rebuilt if parts are available, or it may be more sensible to replace it, especially if the model is discontinued and every future repair will be a hunt for parts.
Security matters too. If a lock is failing and also has keys floating around from former employees, replacing the cylinder or re-keying at the same time can make more sense than patching the old setup. We will tell you when a repair is genuinely enough, and we will say so when replacement is the better long-term decision.
Fire-rated and code-governed doors need extra care. Hardware on those doors cannot always be swapped for anything that fits. If your door is part of a rated opening or is an exit, we will point that out before recommending a change, and we may need to confirm requirements with you or your building owner.
How much does commercial door repair cost in San Gabriel?
We do not quote numbers on a web page, because a door that will not latch can cost very little or quite a bit depending on the cause, and anyone quoting a figure without seeing it is guessing. What we can do is explain what moves the cost, so you know what to expect when we give you a real number.
In general, adjusting a strike or re-aligning a door is the lighter-cost route, and a full mortise lock replacement with a matching trim sits at the other end. Whichever it is, we explain it before work starts.
- The cause. Alignment and adjustment work is very different from replacing a worn lock body.
- The hardware type. Standard cylindrical sets are generally easier and more economical to source than a heavy-duty mortise lock or a specialty exit device.
- Parts availability. Older or discontinued mortise models can take longer to match, and sometimes a full replacement is the practical answer.
- Door condition. A warped, sagging, or damaged door or frame may need work before any lock will behave.
- Keying. Re-keying, keying to match an existing system, or restricted keyways add to the job.
- Time of day. Emergency visits at night, on weekends, or on holidays differ from scheduled daytime work.
- Travel and scope. Number of doors, access to the door, and how far the van has to go all play a part.

Call (213) 577-1366What does commercial door hardware work look like around San Gabriel?
San Gabriel has a real mix of commercial settings, and the hardware problems follow the setting. Along the Valley Boulevard corridor, the Golden Mile near San Gabriel Square, restaurant and storefront lock service is a routine kind of call. Doors that open and close all day and get locked up late are exactly where latches wear, closers drift, and strikes work loose. A front door that still locks but no longer catches reliably is the typical early warning, and it is much cheaper to deal with then than after it fails during a closing shift. For the front-of-house side of that work, see our storefront lock repair page.
Near San Gabriel Valley Medical Center, lock work for medical offices has its own character. These suites tend to have several interior doors with different access needs: a front door, a records or supply room, staff-only areas. When one of those latches fails, the question is often not only how to fix it but how it fits the keying across the suite. That is where a master key system becomes a useful conversation, and where electrified or keypad hardware may come up through access control installation.
Over on the Las Tunas Drive corridor, condo complexes bring gate and mailbox lock service, which sits close to commercial hardware in practice because the equipment is shared and used by many people. Gate latch problems are covered separately under gate lock repair. The Del Mar Avenue corridor is a mix of denser, postwar apartment and condo buildings and commercial frontage, so a call from there can be a building entry door, a shop door, or a service door off an alley.
Whether your address falls in 91775 or 91776, the same process applies. One local detail worth knowing: San Gabriel has hot, dry summers, and heat can swell wood doors. A wood door that latches fine in spring and starts rubbing the frame in July is often a seasonal swelling problem, not a failed lock. It is a routine issue rather than a severe one, but it is worth checking before you replace hardware that is working. We serve San Gabriel from our Westwood storefront, about 22 miles away, with mobile vans that carry common commercial parts.
Why call Wilshire Lock & Key for commercial door hardware?
We have been in business since 1987, and that is a long time to have seen how commercial hardware ages. We are one company with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, not a dispatch service that passes your call to whoever picks it up. The person who answers the phone at (213) 577-1366 is part of the same business that sends the van.
David, the owner and lead technician, oversees the work. That matters on commercial jobs, where an honest recommendation is often the difference between a short repair and a repeated one. If you are comparing locksmith companies, ask each one for its California BSIS locksmith company (LCO) license number. California requires locksmith companies to hold that license, and any reputable company should be able to give it to you without hesitation.
If you are locked out of a business rather than dealing with failing hardware, our business lockout page covers that situation. For broader commercial needs, see our commercial locksmith page.

Call (213) 577-1366What should I check before I call?
You do not need to be an expert. A few observations make the first conversation faster and help us bring the right parts.
If the door is standing open and the building cannot be secured, say so first. That changes the order of what we do.
- Is the door wood, metal, or glass in an aluminum frame?
- Does the latch bolt move in and out freely when you turn the handle, or does it stick?
- Does the door close fully on its own, or do you have to push it?
- Is there visible rubbing, a gap at the top, or a bolt that misses the strike?
- Does the key turn smoothly, or does it grind or spin without effect?
- Has anything changed recently, such as a new tenant, a moved door, or a heat spike?
- Is the door an exit or a fire-rated door?
Frequently asked questions
My commercial door won't latch. Does that mean I need a new lock?
Not necessarily. Many doors that will not latch have an alignment problem, a worn strike, a drifted hinge, or a weak closer rather than a dead lock. We check those first and only recommend replacement when the lock itself is the failing part.
Can you fix a commercial door that won't lock at night?
Yes. Call (213) 577-1366 at any hour. We answer around the clock, every day of the year. Our first goal is getting the building secured, then we sort out whether the lasting fix is a repair or replacement.
Do you repair mortise locks, or do they always need to be replaced?
We repair many of them. A mortise lock with a worn latch, a loose trim, or a sticky mechanism can often be serviced. If parts are no longer available or the internals are badly worn, replacement may be the sensible route. We tell you which applies after seeing it.
Do you do office door lock repair and warehouse door lock repair?
Both. Office doors usually involve cylindrical or mortise locksets and sometimes shared keying. Warehouse doors often involve heavier hardware, rim-mounted devices, or doors that take rougher use. We work with all of these.
How do I know whether my door's problem is the heat?
If a wood door sticks or rubs more in summer and eases in cooler weather, swelling from San Gabriel's hot, dry heat may be part of it. A technician can tell by watching how the door meets the frame. It is often an adjustment, not a new lock.
What will it cost to fix my commercial door hardware?
We do not publish numbers because cost depends on the cause, the hardware type, parts availability, door condition, keying, and time of day. Once we have seen the door, we explain the options and what each involves before any work begins.
Is the locksmith you send licensed by the state?
California requires locksmith companies to hold a BSIS locksmith company (LCO) license, and you should ask any locksmith for it before work starts. Our license number is being added to this site, so ask us for it directly when you call.
Can you match new hardware to the keys I already have?
Often yes. We can frequently key new or rebuilt hardware to match your existing keys, which saves you reissuing keys to staff. If the existing system is restricted or unusual, we confirm what is possible when we see it.
