Why won't my commercial door latch or lock?
A commercial door that won't latch or won't lock is rarely a mystery once someone puts hands on it. The usual causes are a latch bolt that no longer lines up with its strike, a worn or gummed-up lock body, a broken internal spring, a door that has dropped on its hinges, or a closer that no longer pulls the door fully shut. From the sidewalk every one of these looks the same: the door sits slightly ajar, or the key turns and nothing happens. What decides the repair is the cause, and the cause is usually found in a few minutes of looking at the hardware rather than guessing at it.
Business doors take far more abuse than a house door. An office entry gets opened many times a day, a back warehouse door gets shoved with a hand truck, and a restaurant's rear door gets kicked open by someone carrying a tray. Hardware wears in predictable places, and it tends to fail at the worst time, usually when you are trying to close up for the night.
If you want to narrow it down before you call, a few quick observations help us a great deal:
- Does the door close fully if you pull it by hand, or does it stop short of the frame?
- Does the latch bolt move freely when you turn the handle, or does it feel stiff, gritty, or loose?
- Is there a shiny wear mark on the strike plate showing where the latch actually lands?
- Did the problem start suddenly, or has it been getting worse over weeks?
- Is the door wood, hollow metal, or aluminum storefront? Each fails differently.
What commercial door hardware problems do we repair?
Commercial door hardware covers more than the lock itself. A door is a system: hinges, latch, lock cylinder, strike, closer, and often an exit device. When one part drifts out of adjustment, the others get blamed. We look at the whole door before deciding what actually needs work, which keeps you from paying for a new lockset when the real fault was a loose hinge.
- Commercial door won't latch: misaligned strikes, worn latch bolts, weak or broken springs, and sagging doors.
- Commercial door won't lock: failed lock bodies, damaged cylinders, stripped cams, and bent or broken deadbolt throws.
- Mortise locks: the heavy-duty lock body set into the edge of the door, common in older commercial and storefront doors.
- Cylindrical and heavy-duty lever locks on office, suite, and storeroom doors.
- Office door lock repair: sticking keys, loose handles, and locks that turn freely but don't retract the latch.
- Warehouse door lock repair: rear and side doors, hasps, and rugged keyed locks that take rough treatment.
- Strike plates and latch guards that have been pried, bent, or worn out of position.
- Re-keying hardware that is otherwise sound, so old keys stop working without replacing the lock.

Call (213) 577-1366How do we handle a commercial door hardware call?
We work the same careful way whether it is a small office door or a rear warehouse entrance. Here is what a typical call looks like from start to finish.
- You call (213) 577-1366. A person answers, any hour of any day, and we ask what the door is doing, what it is made of, and whether the building is currently secure.
- If the door cannot be locked and the business is exposed, we say so plainly and treat it as the priority, because an unsecured door overnight is the real risk.
- A technician arrives in a mobile van carrying common commercial hardware, and examines the whole door: hinges, alignment, latch, strike, cylinder, and closer.
- We tell you what we found before any work starts. Often the answer is an adjustment or a part replacement rather than a new lock.
- We repair, rebuild, or replace the hardware that is actually failing, test the door through many open-and-close cycles, and confirm it latches and locks from both sides.
- If the door can't be fully repaired on the spot, we make it secure for the night and explain what is needed to finish the job, instead of leaving you with a door that only looks fixed.
Mortise locks: repair, rebuild, or replace?
A mortise lock is a lock body that slides into a pocket cut in the edge of the door, and it is common on older commercial doors and many storefronts. It is a strong design, which is why so many are still working decades after installation. It is also why they fail in ways that surprise people. The internal parts are small, the lock body can fill with dirt or dried lubricant, and the faceplate and strike have to line up closely.
Many mortise locks are worth saving. A worn latch, a stuck cylinder, or a tired spring can often be repaired or rebuilt with parts that still exist. A rebuild is usually the more economical route when the lock body and its case are in good shape, because you keep the door preparation as it is and avoid cutting into the door.
Replacement makes more sense when the case is cracked, the door has been cut to fit a lock that no longer matches it, or the lock is a discontinued model with no parts available. If the old lock is at the end of its life, we will say so rather than keep patching it. Sometimes a modern mortise lock fits the same pocket and keeps the door intact. Other times the better answer is a different type of hardware entirely, and we explain the tradeoff.
If the issue is mainly a storefront with a damaged lock or cylinder, our page on storefront lock repair covers that side in more detail.

Call (213) 577-1366What affects the cost of commercial door hardware work?
We don't quote numbers on a web page because two doors that look identical can need very different work. What we can do is tell you exactly what moves the cost, so there are no surprises when we give you a figure in person or by phone.
The biggest factor is whether the repair is an adjustment, a part replacement, or a full hardware swap. Realigning a strike or tightening a loose hinge is a lighter job than replacing a lock body, and replacing a lock body is lighter than replacing a full set of door hardware with a new closer and exit device.
The other main factors are:
- The type of lock: standard cylindrical hardware is generally more economical to repair than a mortise lock with hard-to-find parts.
- Parts availability: current models are simple, discontinued ones may require rebuilding or substitution.
- Door material and condition: a damaged hollow metal frame or warped wood door can add work beyond the lock itself.
- Grade and code needs: fire-rated doors and doors on a path of egress have hardware requirements that limit what can be installed.
- Number of doors and keying: several doors on one key system take more planning than a single door.
- Timing: an after-hours emergency call involves different scheduling than a planned daytime visit.
- Whether the building is currently unsecured, which affects how fast the work has to be completed.
Why call Wilshire Lock & Key for commercial hardware?
Commercial door hardware is a specialty, and it is easy to find someone who will simply replace everything. What we offer is a bit different, and here is the honest list.
We have been in business since 1987. That is a long time to see how commercial hardware ages: which latches wear first, which strikes loosen, and which locks are worth rebuilding. We are one company with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so the person who answers the phone is part of the same operation as the technician who arrives. There is no dispatch middleman passing your call to whoever happens to be free.
David, the owner and lead technician, oversees the work. That matters on commercial jobs because the decisions, such as repair or replace and what to leave alone, are judgment calls and not just parts swaps.
We answer the phone 24 hours a day, 7 days a week, all year, at (213) 577-1366. A door that won't lock doesn't pick a convenient time to fail, and a business can't leave the building open until morning.
If your problem is that the door works but you are locked out of the business, that is a different job, and our business lockout page explains how we handle it. For broader work across a property, our commercial locksmith page is the overview.

Call (213) 577-1366Commercial door hardware in Studio City
Studio City is about 11 miles from our Westwood storefront, and our mobile vans work across the area, including ZIP codes 91604 and 91602. The local mix shapes the kind of hardware work we see.
Ventura Boulevard is the obvious one. Shops and restaurants along the boulevard have front doors that open all day and rear doors that get heavy use after hours. Storefront lock service for those businesses is a regular scenario here, and the failures are usually the ordinary ones: a latch that has worn out, a closer that no longer pulls the door fully shut, or a cylinder that has started to stick. Rear delivery and kitchen doors tend to take the worst abuse.
Tujunga Village, Colfax Meadows, and the Silver Triangle are known for 1920s-40s character homes in Spanish, Tudor, and cottage styles, many with vintage mortise locksets still in service. We spend a lot of time inside those older mortise bodies, and that experience carries directly over to commercial mortise hardware. If you run a small office or studio from an older building in 91604, the same questions apply: can the existing mortise lock be rebuilt, and is it worth keeping?
Apartments and condos cluster north of the boulevard along Moorpark Street and Ventura Place. For the managers of buildings like those, common-area doors, utility rooms, and entry doors are commercial-grade hardware problems even though people live behind them. Our access control installation page covers the next step when keys are no longer enough for a building.
Climate matters too. The canyon and hillside lots, including the Fryman Canyon hillsides and Laurel Canyon hillside streets, get more winter shade and damp than the open valley floor, and that can swell wood doors seasonally. A wood door that latches fine in October and drags in February is a common pattern, and the answer is often adjusting the strike or planing the door, not replacing the lock. Summers here are hot and dry like the rest of the south valley, which is hard on lubricants and on plastic or weather-exposed parts of exterior hardware.
Panic bars, closers, and the hardware around the lock
Many commercial door problems are not the lock at all. A door that won't latch is often a door closer issue: the closer may be too weak to overcome the latch, too strong and slamming, or leaking fluid. If that is what you are dealing with, see our door closer repair page. A rear exit that must open without a key from inside may need an exit device, and our panic bar installation page explains that work.
The reason we raise this is that a repair that ignores the closer or the exit device often fails again in a few weeks. We look at all of it together. When a door is part of an exit path, fire-rated, or covered by accessibility requirements, there are limits on what hardware may be used, and we will tell you if the lock you were hoping to install is not allowed on that door. We do not make code decisions for the building department, but we know when a question needs to go to them.

Call (213) 577-1366How do you keep commercial door hardware working longer?
Most hardware failures are slow, and the warning signs are easy to spot. A little attention early usually prevents an emergency call later.
Start with the door itself. If it needs a shove to latch, or a lift on the handle to lock, the alignment is already off and the latch and strike are wearing in the wrong places. Fixing alignment while the parts are still good is far cheaper than replacing them after they fail.
Keep keys in good condition. A worn or badly copied key wears the cylinder pins inside the lock and leads to sticking and eventually to a broken key. If a key has started to stick, have the cylinder looked at before it jams. Never force a stiff key.
Lubricate only with products made for locks. Heavy oil collects dust and turns to gum, and that gum is behind many of the stuck latches and cylinders we open up.
If employees come and go, think about keys. A master key setup can keep access organized across several doors. Our master key system page explains how that works, and re-keying existing hardware is often more economical than replacing it.
If a door is mainly used by staff, mobile service is normally the simplest way to repair it in place. Our mobile locksmith page describes how that works.
How do I choose a commercial locksmith in Studio City?
Ask direct questions. California requires locksmith companies to hold a BSIS LCO license, which is issued through the Bureau of Security and Investigative Services. You should ask any locksmith you consider for their license number and check it yourself. It is a reasonable question, and a legitimate company will not mind it.
Ask who will actually come to the door, and whether the person answering the phone works for the same company. Ask what will be done before work starts, and ask to be told what is wrong with the hardware, not only what needs to be sold. A good tradesperson will explain the repair and the alternatives and let you choose.
Be careful of anyone who wants to replace every lock on a door without examining the door, and of anyone who cannot explain why a part has failed. Our own approach is simple: look, explain, repair what is actually broken, and test it before we leave.
Frequently asked questions
Why won't my commercial door latch even though the lock seems fine?
The lock is often not the problem. A latch bolt that misses its strike, a door that has sagged on its hinges, a weak closer, or a swollen wood door can all stop the door from latching. We check alignment first, because adjusting a strike or hinge is usually lighter work than replacing hardware.
Can a commercial mortise lock be repaired, or does it have to be replaced?
Many can be repaired or rebuilt, especially when the lock case is sound and parts are available. Replacement is the better choice when the case is cracked, the lock is discontinued with no parts, or the door has been modified to fit something that no longer matches. We tell you which it is before we start.
My office door won't lock and I need to leave tonight. What should I do?
Call (213) 577-1366 any hour. We answer 24 hours a day, every day. If the door can't be fully repaired right away, we can usually make it secure for the night and explain what is needed to finish the repair, so the building isn't left open.
Do you repair warehouse door locks and rear doors?
Yes. Warehouse door lock repair is part of this service, including side and rear doors, hasps, and heavy-use keyed locks. These doors take rough treatment, so we often look at the door, hinges, and strike as well as the lock itself.
How much does commercial door hardware repair cost?
It depends on the work. An adjustment is lighter than a part replacement, and a part replacement is lighter than a full hardware swap. Lock type, parts availability, door condition, fire or egress requirements, the number of doors, and the time of day all matter. We explain the options once we see the door.
Does a door closer problem cause a door not to latch?
Yes, very often. A closer that is too weak won't pull the door fully into the frame, and one that is leaking or set badly can also cause trouble. We check the closer along with the latch, and you can read more on our door closer repair page.
Do wood doors in Studio City's hillside areas stick in winter?
They can. Canyon and hillside lots get more winter shade and damp than the open valley floor, and that can swell wood doors seasonally. A door that drags or won't latch in winter but works in summer often needs a strike or door adjustment rather than a new lock.
Is your locksmith company licensed for commercial work?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it and verify it. Our license number is being added to this site. In the meantime, you can call (213) 577-1366 and ask us directly.
Will you come to my business in Studio City, or do I have to bring the lock in?
We come to you. Our mobile vans serve Studio City, including ZIP codes 91604 and 91602, and we also have a storefront at 10740 Wilshire Blvd in Westwood. Most commercial door hardware work is done in place at your door.
