Why won't my commercial door latch or lock?
Most calls we get about commercial doors start the same way: the door closes but the bolt doesn't catch, the key turns but nothing moves, or the handle spins loose. Those are three different problems with three different fixes, so the first job is working out which one you have.
A commercial door that won't latch is usually an alignment or wear problem. Hinges loosen after years of heavy traffic, the door sags a fraction of an inch, and the latch bolt no longer lines up with the strike plate. Sometimes the latch itself is worn or gummed up, or the spring inside has gone weak. Sometimes the door is being slammed so hard that the strike plate has bent or the frame has shifted.
A commercial door that won't lock is a different story. The cylinder may be worn so the key no longer engages properly, a spindle or tailpiece inside the lock may have snapped, or the deadbolt can't extend because the door has drifted out of line. A mortise lock, the boxy lock body set into the edge of the door, has more internal parts than a typical residential knob set, and any one of them can fail.
The reason to deal with it quickly is simple. An office door lock that only half works is a security gap, and a warehouse door lock that won't hold leaves inventory and equipment exposed. If you can't secure the building tonight, call (213) 577-1366. We answer at every hour.
How do we handle commercial door repair, step by step?
We try to diagnose before we replace anything. Many doors that look like they need new hardware actually need an adjustment, a cleaning, or one small part. Here is how a typical visit runs.
- You call (213) 577-1366 and tell us what the door does: won't latch, won't lock, key sticks, handle is loose, or door won't stay shut. The more specific you are, the better we can prepare the van.
- A technician from our mobile service arrives and looks at the whole door, not just the lock. We check hinges, frame, strike plate, closer, and the way the door swings and meets the frame.
- We test the hardware: the latch bolt, the deadbolt throw if there is one, the cylinder, the trim or lever, and the internal spindle. On a mortise lock this may mean taking the lock body out of the door edge to see what is going on inside.
- We tell you what we found in plain terms and whether the lighter-cost option is a repair, an adjustment, or a replacement of one component. If a full replacement makes more sense, we explain why.
- We do the work, then test the door repeatedly from both sides with the key and without it, including closing it the way your staff closes it at the end of the day.
- If the door can't be fully fixed on the spot, for example because a specific lock body needs to be sourced, we make it secure for the night and tell you what happens next.

Call (213) 577-1366What commercial door hardware do we repair and replace?
Commercial hardware is built for more cycles and more abuse than residential hardware, and it is made differently. Here is what we work on under this service.
- Mortise locks and mortise lock bodies, including worn latches, broken springs, and failed internal parts
- Latch bolts and strike plates that no longer line up, including bent or worn strikes
- Lever handles and trim that spin, droop, or no longer retract the latch
- Commercial cylinders that are worn, sticking, or no longer turning the cam
- Deadbolts on office, shop, and back-of-house doors
- Storeroom and utility-room locks on interior doors
- Hinges and door alignment where sag is what's causing the latch to miss
- Exit devices, where the repair touches the latch; for new or replacement bars see our panic bar installation page
Is the closer part of the problem?
Often, yes. A door that won't latch is sometimes just a door that closes too slowly, so the bolt never gets pushed in time, or too fast, so it slams into the strike and chews it up over the months. If the lock is fine but the door fights you on the way shut, the closer needs attention, and that is its own repair. We cover it on the door closer repair page.
We always check the closer during a latch call because fixing the lock and ignoring the cause just brings the problem back.
Should I repair or replace the hardware?
Repair is usually the more economical route when the lock body is basically sound and the issue is alignment, a worn strike, a loose trim, or a single failed part. Replacement makes sense when several parts have worn out together, when the lock is so old that parts are no longer made, or when the door has been forced and the lock body is damaged.
A few signs point toward replacement rather than another repair:
- The lock has been repaired more than once for the same fault
- The cylinder is worn enough that keys are hard to cut and fit
- The lock body is cracked or the faceplate is bent from a forced entry attempt
- Keys have been lost or passed around so much that you no longer know who has one
- You want the door to work with a keypad, card reader, or other electronic system
What affects the cost of commercial door hardware work?
We don't quote numbers on a web page because the same symptom can have a very small cause or a much larger one. What moves the cost is mostly this:
The type of hardware is the first factor. A standard cylindrical lever is a different part from a mortise lock body, and a heavy-duty or specialty mortise can cost more to source than a common one. The second factor is repair versus replacement: adjusting a strike and tightening hinges is a lighter job than replacing a lock body and fitting new trim.
Door and frame condition matter too. If the frame is out of square, or the door has sagged because the hinge screws no longer hold in the jamb, some of the work is carpentry-adjacent, not just lock work. Metal and wood frames each need their own approach.
Then come the practical factors: how many doors are involved, whether you need the doors keyed alike or on a master system, whether the job is during business hours or in the middle of the night, and whether the building needs to be secured immediately. Keying many doors to work together is a decision of its own; see our master key system page if you are thinking about that.
We would rather give you a straight estimate after seeing the door than guess over the phone. If the work turns out to be more than we first expected, we say so before we start.

Call (213) 577-1366What does commercial door hardware mean for Glendora properties?
Glendora is a mix of old and new commercial settings, and that shapes the hardware calls. Around Glendora Village, merchants often work in older storefront buildings where doors have been opened and closed for many years. Wear shows up as loose levers, sticky latches, and strike plates that no longer line up. If you run a shop there and your front or back door has become unreliable, our storefront lock repair page covers that side of the work, and the hardware repairs described here are often part of it.
Along the Route 66 (Alosta Avenue) corridor, condos and apartments concentrate, which means shared doors: common entries, utility rooms, and service doors that many people use all day. Those doors take more cycles than a private door, and the hardware wears out faster. Property managers there are often dealing with latches that don't catch or locks that are stiff, and we repair them the same way we would any commercial door.
Any shop or office near the Citrus College area, or elsewhere in South Glendora, faces similar wear from steady foot traffic. Whether your address falls in 91740 or 91741, the work is the same: find out whether the problem is alignment, a worn component, or a lock that has simply reached the end of its life.
The climate matters too. Glendora summers are hot and dry, and Santa Ana wind events come off the canyons. Heat makes south-facing doors expand slightly, which can change how a latch meets its strike, and weatherstripping wears out sooner. A door that latches fine in winter may start to stick in the afternoon heat. Wind-blown dust also finds its way into exterior locks, especially on hillside properties, and gums up latches and cylinders. If a Glendora door only fails in certain weather, that's a clue we use during diagnosis.
We are based in Westwood, about 37 miles from Glendora, and our mobile vans come to you. Details on how we cover the city are on our Glendora locksmith page.
What should I do before calling about a door that won't latch?
A few quick checks help, and none of them requires tools. They also give us useful information when you call.
Close the door slowly and watch where the latch bolt meets the strike plate. If it hits above, below, or beside the opening, you have an alignment issue. Press on the door while turning the key; if it locks only when you push, that points to sag or a frame that has shifted. Try the lever from both sides to see whether it springs back firmly or feels loose. Look for marks on the strike plate that show where the bolt has been landing.
Please don't spray heavy oil into a commercial lock to quiet a sticking latch. It works for a day and then attracts dust, which is a real concern with Glendora's wind and dry summers. If you're locked out of a business entirely rather than dealing with a faulty door, our business lockout service is the right page.
If the door is damaged by a break-in attempt, tell us when you call. We will treat it as a security issue first and a hardware issue second.

Call (213) 577-1366Why call Wilshire Lock & Key for commercial door hardware?
We have been in business since 1987. That is a long time to see what fails on commercial doors and why, and it is the reason we diagnose first instead of selling you a new lock because that is easiest.
We have a storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties. When you call (213) 577-1366, you reach us, not a dispatch middleman who passes the job to whoever is closest. The phone is answered 24 hours a day, 7 days a week, all year.
David, the owner and lead technician, oversees the work. If a commercial door job is unusual or complicated, it gets his attention.
One thing to do with any locksmith, including us: California requires locksmith companies to hold a BSIS LCO license, and you should ask to see it. It is a reasonable question for a business owner to ask about someone working on the doors that protect your property.
If your problems go beyond one door, such as several doors, a rekey, or a new security setup, our commercial locksmith page covers the wider picture. If you want to move to card or keypad entry on doors that currently use keys, our access control installation page explains that route. For anything else, you can reach us through our contact page or just pick up the phone.
Frequently asked questions
Why does my commercial door close but not latch?
The most common cause is that the door has sagged slightly or the frame has shifted, so the latch bolt no longer lines up with the strike plate. Worn latches, weak springs, and a closer that is too fast or too slow can also be the cause. We check all of these before deciding whether to adjust, repair, or replace.
Can you fix a commercial door that won't lock without replacing the whole lock?
Often, yes. If the issue is a worn cylinder, a broken spindle, a bent strike, or misalignment, one part or an adjustment may be enough. We replace the whole lock when several parts have worn out together or the body is damaged.
Do you handle office door lock repair as well as warehouse door lock repair?
Yes. Office doors, storerooms, back-of-house doors, and warehouse doors all use commercial hardware, and the diagnostic process is the same. The difference is usually the type of lock and how heavily the door is used.
What is a mortise lock, and can it be repaired?
A mortise lock is a lock body set into a pocket cut in the edge of the door, usually with a latch, sometimes a deadbolt, and trim on both sides. Many can be repaired by replacing worn internal parts, springs, or the cylinder. If the body is badly worn or parts are no longer made, replacement is the better option.
Can Santa Ana winds and heat really affect my door lock?
They can. Heat can expand south-facing doors and change how the latch meets the strike, and wind-blown dust gets into exterior locks and gums up latches and cylinders, especially on hillside properties. If a door only misbehaves in certain weather or at certain times of day, tell us.
How much will commercial door hardware repair cost?
We don't give numbers without seeing the door. Cost depends on the type of hardware, whether it is repair or replacement, the condition of the door and frame, how many doors are involved, and whether you need the work after hours. We give you a clear estimate after we diagnose it, and we tell you before starting if the job grows.
Do you come out outside normal business hours?
Yes. We answer the phone 24 hours a day, 7 days a week, year-round at (213) 577-1366. If your door can't be secured at night or on a weekend, call and we will make it secure.
How do I know the locksmith I hire is properly licensed?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for their license number before they start work, and check it with the state if you want to be sure. It's a normal question and a good one to ask.
