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 it closely. In our experience the cause is usually one of a handful of things, and most of them are mechanical wear or movement rather than a failed lock in the sense people imagine.
The door and frame have drifted out of alignment. Hinges loosen, a heavy door sags a little each year, and the latch bolt no longer lands in the strike opening. You hear the click, or you don't, and the door drifts open on its own. Sometimes the fix is as simple as adjusting the strike. Sometimes the hinges, the door edge or the frame need attention first, and moving the strike would only hide the problem.
A door that won't lock is a different complaint with different causes. The cylinder may be worn or gummed up, the cam or tailpiece behind it may have broken or slipped, the bolt may be catching on a misaligned strike, or the inside of a mortise case may have a broken spring or a worn part. A key that turns with no resistance and no bolt movement usually points to a broken connection inside the lock. A key that sticks or only works with jiggling points to the cylinder or the key itself.
The first job on any call is telling those cases apart, because the right repair depends on it. Replacing a whole lock when the real issue is a loose hinge wastes your money, and adjusting a strike when the lock body is failing leaves you with a door that fails again next month.
- Door closes but the latch doesn't catch: usually strike alignment, hinge sag, or a worn latch bolt.
- Door latches but won't lock: usually the cylinder, cam, or the deadbolt not reaching its strike.
- Door won't stay closed unless pushed: often closer adjustment, a swollen or warped door, or a spring failure in the lock.
- Handle spins freely or feels loose: often a broken spindle, a loose set screw, or a worn trim.
What commercial door hardware do we repair and replace?
Commercial hardware is built differently from the hardware on a typical house door, and that matters when something fails. Parts are heavier, tolerances are tighter, and one door may have a lock, a closer, an exit device, hinges and an electric strike all working together. We handle the mechanical side of that whole assembly.
If you need broader business security work beyond the door itself, our commercial locksmith service page covers the bigger picture. This page is about the hardware that makes an individual door latch, lock and close properly.
- Mortise locksets: the heavy lock body set into a pocket cut in the door edge, common in older office buildings and storefronts.
- Cylindrical and heavy-duty bored locks: the lever or knob sets found on many office suites, stockrooms and back-of-house doors.
- Latches, latch bolts and deadlatches, including worn or sticking latch mechanisms.
- Strike plates and strike boxes, including re-aligning, re-cutting the frame opening, and replacing worn strikes.
- Cylinders and cores, including rekeying or replacing them when a lock is worn or keys are lost.
- Hinges, including tightening, re-setting, and replacing worn commercial hinges that cause sag.
- Lever handles, spindles and trim that have loosened, snapped or worn out.
- Warehouse and rear-door hardware, such as hasps, slide bolts and heavy-duty deadbolts on service doors.

Call (213) 577-1366How do we fix a commercial door that won't latch?
We work the same logical order every time, because skipping the diagnosis is how doors end up fixed twice. Whether we come to you in a mobile van or you bring a removable lock case to our Westwood storefront, the sequence is the same.
- Talk it through. When did it start, does it happen only in certain weather or at certain times, and has anyone worked on the door recently? Those answers often narrow the cause before we touch anything.
- Check the door in its frame. We look at hinge condition, gaps along the edge, how the latch meets the strike, and whether the door has dropped, swollen or twisted.
- Test the hardware by itself. We operate the lock, latch and handle with the door open, so we can tell whether the mechanism works on its own or only fails when the door is closed.
- Try the least invasive fix first. That might be tightening hinge screws, adjusting or re-setting a strike, lubricating the proper parts, or adjusting a closer.
- Repair or replace the failed part. If a spring, cam, cylinder, latch bolt or lock case is worn out, we explain what we found and what we recommend, including whether a repair is realistic.
- Test again under real use. We cycle the door repeatedly, with keys and from the inside, and confirm it latches and locks on its own before we leave.
- Leave you with working keys and a clear explanation of what was done, so whoever manages the space knows what changed.
Should you repair the hardware or replace it?
We lean toward repair when repair is sound, because it usually keeps cost down and avoids re-keying a whole suite. But repair has limits, and we'll say so plainly.
Older mortise cases can often be serviced, and replacement parts exist for many common designs. Others are obsolete, worn through, or already broken in ways that make repeated repair a poor investment. When parts can't be found, or when the lock has been repaired more than once and keeps failing, replacement is the more honest recommendation. If you want a deeper look at the broader repair-versus-replace question, our lock repair and lock replacement pages go into it.
For doors in public or semi-public spaces, we also look at whether the existing hardware still suits how the door is used. A lock that was fine for a quiet back office may not hold up on a door that opens hundreds of times a day. We'll tell you when the better move is a heavier-duty grade of hardware, and when what you have is perfectly adequate.

Call (213) 577-1366What affects the cost of commercial door hardware repair in Los Angeles?
We don't quote prices on a web page, because the honest answer depends on the door in front of us. What we can do is tell you what moves the cost up or down, so nothing on the estimate surprises you.
Often the usually more economical route is an adjustment or a single-part repair rather than swapping a whole lockset, and we'll point that out when it applies.
- Whether the fix is an adjustment, a part repair or a full replacement. Adjusting a strike is a very different job from rebuilding or replacing a mortise lock.
- The grade and type of hardware. Heavy-duty commercial locks and specialty mortise cases cost more than light-duty sets, and parts availability varies a lot.
- The door and frame material: wood, hollow metal, or aluminum storefront. Each needs different prep and different fasteners.
- Whether the door needs prep work, such as re-cutting a mortise pocket, filling and re-drilling holes, or repairing a damaged frame.
- How many doors are involved. Several similar doors on one visit are often handled more efficiently than one door at a time.
- Electrified or access-controlled hardware, which adds wiring and compatibility considerations.
- Timing. Emergency and after-hours calls involve different logistics than a scheduled daytime visit.
- Finish and appearance matching, if you want new hardware to look like the existing hardware on neighboring doors.
- Rekeying or master key work done at the same time as the repair.
How does commercial door hardware work out across Los Angeles neighborhoods?
Los Angeles is a wide city, and the doors we see differ from one part of it to the next. Here's what the local picture looks like for door hardware.
Downtown, storefront hardware and panic-hardware repair is a regular part of the work in the Historic Core and Fashion District, around ZIP codes like 90014 and 90012. Many buildings downtown are early-1900s commercial structures, and some have been converted into lofts. Original mortise locksets and older hardware are still common in older buildings, so latch and strike problems often come from decades of door movement. If you run a shop there, our storefront lock repair page covers the front-door side, and panic bar installation covers exit devices.
In Century City, office suite rekeying and suite-door hardware is common in the towers around ZIP 90067. Suite doors in a multi-tenant building usually need to stay tied to a building key plan, so before we change anything we ask who controls the keying. In Westwood (90024), the Wilshire Corridor condominium high-rises and the commercial blocks near UCLA and Westwood Village mean a steady mix of building-access and shared-space doors, many managed by HOAs or property managers who have their own rules on who may alter hardware.
Further into Mid-Wilshire (90036) and Koreatown, older buildings with mortise locks are common, and we see the same pattern there: original hardware that has aged well but now needs attention. Mar Vista, Palms and Sawtelle add small commercial strips and ground-floor shops under apartment buildings.
Weather plays a small role. The Westside gets regular morning marine layer, which can leave exterior hardware damp, and older wood doors on the foggier Westside can swell slightly with the seasons. That occasionally explains a door that sticks or fails to latch only at certain times of year. Inland areas run warmer and drier, so that particular cause is rarer there.

Call (213) 577-1366What's different about office, warehouse and storefront doors?
Where the door is changes what we look for first, and it changes what a good repair looks like.
Office doors, whether a suite entry or an interior door, get a lot of use but little abuse. Failures here are usually wear: loose levers, tired latches, a cylinder that sticks. The bigger question is often keying. If you have an office door lock repair on a suite, we'll check who holds keys and whether the lock should be rekeyed while we're there. If your suites are on a key system, our master key system page explains how that works.
Warehouse and rear-service doors take more punishment. They get kicked, rolled into with carts, left propped, and exposed to weather and dust. Warehouse door lock repair is often about heavy-duty replacement parts, reinforced strikes, and hinges that can carry the load. A door that can't hold its alignment under real use needs more than a new latch.
Storefront doors combine glass, aluminum and constant public use. Latches and cylinders wear quickly, and doors that close on their own depend on a working closer. If the problem is the closing speed or the arm rather than the lock, our door closer repair page covers that side. If your door is wired for card or keypad entry, the access control installation page explains that work separately; here we focus on the mechanical hardware that the electronics depend on.
What about fire-rated and life-safety doors?
Some commercial doors do a safety job as well as a security job. Exit doors need to open easily from the inside, and fire-rated doors are meant to close and latch on their own. We will not repair a door in a way that defeats either function. That means we won't disable a latch to get around a stubborn alignment problem, and we won't leave a door that has to self-latch held open or non-latching.
If your door is part of a rated assembly, tell us when you call. Hardware on those doors has to suit the assembly, and your building owner, property manager or the authority that inspects your building may have requirements we should know about. We'll tell you what we can fix and when the right next step is checking with them.

Call (213) 577-1366How to choose a commercial locksmith in California
California requires locksmith companies to hold a Locksmith Company license, the LCO license, issued through the Bureau of Security and Investigative Services (BSIS). Ask any locksmith you're considering for that license number, and check it with BSIS. That applies to us too, and you're right to ask.
Beyond the license, a few simple checks help. Ask for a plain explanation of what's wrong before work starts. Ask whether the repair or replacement is the better call and why. Be cautious about anyone who recommends replacing everything without looking closely at the door. And if the price discussion only starts after the work is done, that's a red flag.
Frequently asked questions
Why does my commercial door close but not latch?
Most often the latch bolt and strike have drifted out of alignment, usually from loose or sagging hinges or a door that has shifted in its frame. Less often the latch bolt is worn or sticking inside the lock. We check the door in its frame first, then the hardware by itself, so the fix targets the real cause.
Can you repair an old mortise lock, or does it have to be replaced?
Often it can be repaired. Many older mortise cases can be serviced and have parts available. Some are worn through or obsolete, and then replacement is the better choice. We'll tell you what we find and which option makes sense, including when repair isn't realistic.
My office door won't lock even though the key turns. What's wrong?
A key that turns freely without moving the bolt usually means a broken connection inside the lock, such as a cam, tailpiece or internal spring. It can also be a bolt that isn't reaching its strike. We'd need to see the door to say which, and we'll check before suggesting replacement.
Do you handle warehouse door lock repair?
Yes. Warehouse and rear-service doors take heavier use, so we look at the hinges, the strike reinforcement and the grade of hardware as well as the lock itself. A door that can't hold alignment under real use usually needs more than a new latch.
Can you come outside business hours for a commercial door that won't lock?
We answer the phone 24 hours a day, 7 days a week, year-round, at (213) 577-1366. If a door can't be secured, call and tell us what's happening. We'll talk through options for securing the space and getting the hardware fixed. Timing affects the logistics, and we'll explain that when you call.
How much does commercial door repair cost?
It depends on what's wrong and what's on the door. The main factors are whether it's an adjustment, a part repair or full replacement, the grade of hardware, the door material, how many doors are involved, and whether it's an after-hours call. We explain the scope and cost drivers before work starts.
Will you rekey the lock while you're fixing the door?
If you want it, yes. Rekeying at the same visit makes sense when keys have been lost, when staff have changed, or when a lock is being replaced anyway. In multi-tenant buildings, we first check who controls the key plan so we don't disrupt building access.
Can you fix hardware on a fire-rated or exit door?
We can repair or replace hardware on those doors, but we won't make changes that stop a door from closing, latching or opening for exit. Tell us at the start if the door is rated, and we'll work within that. For code questions, your building owner or inspecting authority has the final say.
How do I know a locksmith is legitimate in California?
Ask for the company's BSIS LCO license number and verify it with the state. California requires locksmith companies to hold that license. Also look for a real local address and a straight explanation of the work before it begins.
