Why won't my commercial door latch or lock?
A commercial door that will not latch is usually one of a handful of problems, and most can be narrowed down by looking closely at the door for a few minutes. The door swings shut but the latch bolt rides on the face of the strike instead of dropping into it. The lever turns but nothing retracts. The key goes in but the cylinder spins loose. Or the door looks fine until someone pulls on it after closing time and it opens. Each of those symptoms points to a different part.
When a commercial door won't lock, the cause is nearly always in one of three places: the lock body inside the door, the strike and frame, or the door itself. A mortise lock is a steel case set into a pocket cut in the edge of the door. Inside it are springs, a latch bolt, a deadbolt and the parts the key or lever moves. Those parts wear with every cycle, and a door at a busy entrance gets cycled hundreds of times a day. A bolt that fit tightly years ago may now sit a sixteenth of an inch out of line with its strike, and that is enough to stop it from catching.
Before you call, a few observations help us a great deal. Notice whether the door latches when you hold it firmly closed. Notice whether the key turns freely or feels gritty. Check whether the door drags on the floor or rubs the frame, and whether the closer pulls it all the way shut every time. None of that needs tools, and it lets us bring the right parts in the van instead of guessing.
Which commercial door hardware problems do we repair?
Commercial door hardware covers a lot more than a lock. The lock, latch, strike, trim, hinges, closer and frame all work as one system, and a failure in any one of them can look like a lock problem. Here is what we routinely deal with on shop, office and warehouse doors:
- Mortise lock bodies that stick, skip, or no longer throw the bolt all the way out
- Latch bolts and spring latches worn down so the door will not catch
- Strike plates that are bent, loose, or no longer lined up with the latch
- Lever handles and knob trim that droop, spin loose, or fail to pull the latch back
- Cylinders that are worn, gritty, or no longer turn the lock properly
- Hinges that have loosened and let the door sag out of square
- Deadlocks and auxiliary locks on storefront, office and back doors
- Doors that latch fine open-and-close by hand but not when the closer swings them shut

Call (213) 577-1366How do we fix a commercial door that won't latch?
The order matters. Replacing a lock that was never the problem wastes your money and leaves the door still failing, so we work from the simplest cause to the most involved one.
- You call (213) 577-1366 and describe what the door is doing. We ask what kind of door it is (wood, hollow metal or aluminum storefront), what the lock looks like, and whether the door can be secured right now.
- We come to the location in a mobile van carrying common mortise bodies, latches, strikes, cylinders, trim and hinge hardware, so many repairs can be finished on the first visit.
- We look at the whole door first: how it hangs, where the latch meets the strike, how the closer behaves, and whether the frame has shifted. Sag and misalignment are among the most frequent hidden causes.
- We test the lock itself by removing the trim and checking the bolt travel, the springs and the cylinder connection, so we know whether the hardware is repairable or has reached the end of its life.
- We make the repair that fits. That may mean adjusting hinges, re-seating or moving a strike, replacing a worn latch, rebuilding or swapping the lock body, or fitting a new cylinder.
- We cycle the door repeatedly, from both sides, with the closer working, and confirm it latches and locks properly before we leave. We then go over what we found so you know whether anything else is worth watching.
Should the hardware be repaired, replaced, or upgraded?
Repair is usually the more economical route when the lock body is sound and the trouble is alignment, a worn latch or a loose strike. Those are small parts, and fixing them restores the door without disturbing the rest. If the door has been sagging, we correct the hinges first, because a new lock installed on a dropping door will fail the same way.
Replacement makes more sense when the lock case is worn through, when parts for an old unit are no longer practical to find, or when the same door has been repaired more than once. Replacing the whole lock body is not always a bigger job than it sounds, since many mortise pockets accept a modern body in the same cut. We will tell you honestly when a repair is worth doing and when it is only buying a few months.
An upgrade is a separate decision. If you are replacing hardware anyway, it is a reasonable moment to think about how many people hold keys and who should be able to open what. Our commercial locksmith page covers that wider work, and our master key system page explains how keys can be organized so that staff, managers and owners each open only the doors they should. We keep that conversation optional. If you only need the door to latch, that is what we fix.

Call (213) 577-1366What affects the cost of commercial door repair?
We do not quote numbers on a web page, because two doors that look alike can be very different jobs. What we can do is tell you plainly what moves the cost up or down, so there are no surprises when we give you a figure over the phone or on site.
- Whether the problem is adjustment and small parts, or a full lock body that has to be replaced
- The grade and type of the existing hardware, since heavier mortise locks and specialty finishes cost more to match
- Door material and condition: a straight steel or aluminum door is simpler than a warped or damaged wood one
- Frame damage, which is sometimes the real cause and takes more work to correct than the lock itself
- How many doors are involved and whether they should be keyed alike or on a master system
- Whether the work is an after-hours call-out or can be scheduled during normal business hours
- Parts availability for older or discontinued hardware
- Whether the door also needs a closer, trim or hinge work at the same visit
What does commercial door hardware service look like around Canoga Park?
Canoga Park's commercial doors are not all the same kind of door, and the work changes block by block. In Downtown Canoga Park along Sherman Way, the typical call is a storefront that will not latch properly at closing time, often because the door closer has weakened or the frame has settled. That is where we most often see storefront lock and door-closer repair, and if the closer is the real culprit our door closer repair page is the better fit. For aluminum-frame entrances specifically, see our storefront lock repair work.
Around the Westfield Topanga area, the typical job is retail: shops with several doors, staff turnover, and a need for keys that open the right things. Retail master-key and rekey work is common there, and hardware that won't latch on a stockroom or back-of-house door is often what starts the conversation. Farther along the De Soto Avenue industrial corridor, the work leans toward commercial lock service for warehouses, where heavy doors get used hard, are propped open, and are slammed by forklift operators and delivery crews. Heavy use wears latches and strikes long before it wears anything else.
We work across both Canoga Park ZIP codes, 91303 and 91304, and the Topanga Canyon Boulevard, Roscoe Boulevard and Saticoy Street corridors are all part of the same service area. Our storefront is on Wilshire Boulevard in Westwood, about 21 miles away, and the mobile vans are what actually reach you, so you are not waiting for a shop to open. The far West Valley also has long, hot summers with frequent triple-digit stretches. That heat can swell and shrink wood doors and frames, and the dry Santa Ana wind events in fall are a good reminder to check latches and strikes before the weather changes. Older wood doors in particular can drift out of alignment season to season, so a door that latched in spring may rub or miss the strike by late summer.

Call (213) 577-1366Office and warehouse door lock repair: what is different?
Office door lock repair is mostly about reliability and privacy. Interior office doors, conference rooms and server closets often use lighter-duty lever locks, and the usual failures are a lever that has gone limp, a latch that sticks halfway, or a lock that someone has lost the key to. We repair or replace those, and we can set them up so that a manager's key or a master key still gets in. If a door in a shared suite locks you out, our business lockout service handles that separately.
Warehouse door lock repair is a different problem. Doors are heavier, more exposed and used more roughly. Personnel doors beside roll-up doors, steel back doors, and dock-side entries see abuse from carts and deliveries. The hinges loosen, the door sags a little, and the latch stops reaching the strike. In that setting the fix is often a combination of re-hanging the door properly, replacing a worn latch, and fitting a sturdier strike. Exit hardware is its own category. If the real issue is a crash bar rather than the lock, our panic bar installation page is where that work belongs.
Some businesses are also moving away from keys on certain doors entirely. If that is on your mind, our access control installation page covers it, but repairing the mechanical hardware you already have is a perfectly sensible choice and often the lighter-cost option.
Why call Wilshire Lock & Key for commercial door repair?
We have been in business since 1987, and a lot of what we know about commercial hardware comes from seeing the same failures over and over, on doors of every age and every kind of building. David, the owner and lead technician, oversees the work, so there is a person accountable for how it turns out rather than a call center passing your request along.
We are one company with a Westwood storefront and our own mobile service vans, serving 140 cities across Los Angeles and Ventura counties. When you call (213) 577-1366, it is answered 24 hours a day, 7 days a week, all year, and we are not a dispatch service that hands your job to whichever stranger is closest. That matters at 2 a.m., when you need your shop door secured and want to know who is actually coming.
We will also tell you when something should not be replaced. A lot of commercial door trouble comes from the door, hinges or frame rather than the lock, and we would rather fix the real cause than sell you hardware you do not need. If a repair is likely to be temporary, we say so before we start.

Call (213) 577-1366What should you ask any commercial locksmith before work begins?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you are considering for that license number, and look it up with the state. That is good advice no matter whose name is on the van.
Beyond that, ask what the repair will involve, what is likely to change the price, and whether the problem might be the door or frame rather than the lock. A clear answer to those three questions usually tells you whether the person on the other end knows commercial hardware. If you are weighing several issues at once, our 24-hour locksmith page explains how after-hours calls work.
Frequently asked questions
Why does my commercial door close but not latch?
The most common causes are a strike that no longer lines up with the latch, hinges that have loosened so the door sags, a worn latch bolt, or a closer that is not pulling the door fully shut. We check all four. Often it is a small adjustment rather than a new lock.
My commercial door won't lock with the key. What is usually wrong?
Usually the cylinder is worn or dirty, the lock body inside the door has a failed spring or broken part, or the bolt is hitting the frame because the door has shifted. If the key turns but the bolt does not move, the connection between cylinder and lock body is a likely suspect.
Can you repair a mortise lock, or does it always need to be replaced?
Many mortise locks can be repaired, especially when the case is sound and a latch, spring or cylinder is the problem. If the case itself is worn through, or parts are no longer practical to get, replacing the body is the more sensible option. We tell you which applies after we have opened it up.
Do you handle warehouse door lock repair on the De Soto Avenue industrial corridor?
Yes. Warehouse doors take heavy use, and we service the latches, strikes, hinges and locks on personnel doors, steel back doors and dock-side entries in that corridor. We can also come after hours if a door cannot be secured overnight.
Can you fix an office door lock without changing every lock in the suite?
Usually, yes. If one lock is failing, we can repair or replace just that one. If you also want keys reorganized across several doors, we can discuss a master key arrangement, but that is a separate choice and not required for a basic repair.
How do I know whether the lock or the door is the problem?
If the door drags, rubs the frame, or has a gap that has changed, the door or hinges are likely involved. If it hangs squarely but the key or lever feels wrong, the lock is more likely. Many jobs involve both, which is why we examine the entire door.
Does summer heat in Canoga Park really affect door hardware?
It can, particularly on older wood doors and frames. Long hot stretches swell and shrink the wood, which gradually shifts the alignment between the latch and the strike. A door that worked in spring may start catching or missing by late summer.
Is your phone answered at night and on weekends?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. If a commercial door cannot be locked and your business is exposed, call right away and describe what the door is doing.
How much will my commercial door repair cost?
It depends on whether the fix is an adjustment or new hardware, the type of lock, the condition of the door and frame, how many doors are involved, and whether it is after-hours work. We explain what is driving the cost when we talk through the job, and you can decide before work starts.
