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 looks at it closely. The latch bolt is supposed to slide into the strike plate cleanly every time the door closes. When it doesn't, something in that chain has moved, worn, or broken. On a commercial door the chain is longer than on a house door, because the lock, the closer, the hinges, and the frame all have to agree with each other.
These are the causes we find most often:
- Hinge wear and door sag. After years of heavy use the door drops a little, and the latch no longer lines up with the strike opening.
- A strike plate that has shifted, bent, or pulled loose, or a frame that has moved.
- A worn or broken latch bolt, spring, or internal part inside a mortise lock case.
- A door closer that is out of adjustment, so the door stops just short of closed or slams hard enough to damage the hardware.
- A worn cylinder, so the key turns hard, catches, or won't throw the bolt.
- Wood door edges that have swollen, shrunk, or warped with the seasons.
- Paint, grit, or debris packed into the latch hole or the strike pocket.
What commercial door hardware do we repair and replace?
Commercial door hardware is much more than the lock. We work on the whole set of parts that make a door close, latch, lock, and open the way it should. That includes mortise lock cases, cylindrical and bored lever locks, deadlatches, strike plates, hinges, cylinders, and the trim and latch side of exit hardware.
Some problems have their own page. If the lock is fine but the door drifts shut slowly or slams, that is usually door closer repair. Aluminum and glass entrance doors have their own quirks, covered under storefront lock repair. If you need new push-bar exit hardware rather than a fix, see panic bar installation.
This page is about the hardware itself: getting a door to latch, lock, and release reliably again, whether it serves an office, a shop, a storeroom, or a warehouse.
- Mortise locks: storeroom, office, entrance, and classroom-style functions
- Cylindrical and bored lever locksets
- Latch bolts, deadlatches, and strike plates
- Hinges, pins, and loose or stripped screw holes in the frame
- Commercial cylinders, including rekeying them to a new key
How we handle a commercial door that won't latch, step by step
The order matters. Most hardware complaints are fixed faster and cheaper when we find the real cause first instead of swapping the lock and hoping.
- You call (213) 577-1366 and tell us what the door does: won't latch, won't lock, key sticks, handle spins, or door has to be lifted to close. Tell us if it's wood, hollow metal, or aluminum and glass, and whether it is an exit door.
- We come to the door with a mobile van. The cause is often the door and frame rather than the lock alone, so we want to see the whole opening.
- Before touching anything, we cycle the door several times. We watch where the latch meets the strike, check for hinge play, and see how the closer brings the door in.
- We tell you what we found in plain words, and whether the better path is repair or replacement. The cost is explained before any work starts.
- We do the work: realign or replace the strike, tighten or replace hinges, rebuild or replace the latch or lock body, swap the cylinder, or adjust the closer.
- We test it properly. The door has to latch by itself from partly open, the key has to work smoothly, and the inside has to release without a struggle.
- We tell you about anything else we noticed, such as a damaged frame or a worn closer, so you can decide on your own schedule.

Call (213) 577-1366Repair or replace: how we decide
Many commercial locks are built to be serviced. A good mortise case can often be repaired with new internal parts or a new cylinder, and a door with a misaligned strike may only need the strike moved. That is usually the more economical route, and we'll say so when it applies.
Replacement makes more sense when the lock body is cracked or worn throughout, when parts are no longer made, or when a light-duty lock has been put on a door that sees constant traffic. In that case a repair only buys a short reprieve. We'll explain the difference and let you choose.
Two things we won't compromise on. First, a door that is meant to latch on its own must keep doing so, so we never defeat a latch to make a door easier to close. This matters especially on fire-rated doors, where how the door latches is part of what makes it work. Second, an exit door has to open from the inside without keys or special knowledge. If you are unsure what your building requires, check with your building owner or the local fire authority, and we'll work to that.
What affects the cost of commercial door hardware work?
We don't quote prices on a web page, because two doors that both won't latch can be very different jobs. Here is what actually moves the cost:
- Whether the fix is an adjustment, a repair, or a replacement. Realigning a strike is a different job from replacing a mortise lock body.
- The grade and type of hardware. Heavy-duty commercial locks and common light-duty ones differ in cost and in how long they last.
- Parts availability. Common lock bodies are simple to source, while older or discontinued ones can take more effort, and sometimes a matching replacement isn't possible.
- The door and frame. A damaged hollow metal frame or a warped wood door can make the job larger than the lock itself.
- How many doors are involved, and whether you want them keyed alike or on a master key system.
- Special requirements such as fire-rated or exit doors, which limit what can be installed.
- Timing. A middle-of-the-night call for a door that can't be secured is a different situation from a weekday appointment.
Office door lock repair and warehouse door lock repair: what's different
Office doors tend to fail from age and use. A lever that has been turned thousands of times loosens, a latch wears, and a closer slowly drifts out of adjustment. Office door lock repair often means a new latch or cylinder, or a mortise case rebuilt, and getting the door to close without anyone having to push it. Interior office doors and a main entrance can need very different hardware, and we check which function each door really needs.
Warehouse door lock repair is a different problem. Personnel doors in warehouse and shop buildings take hits from carts, pallets, and hurried shoulders. Dust gets into latches, strikes get bent, and hinges loosen under weight. The fix is often sturdier hardware, a reinforced strike, or hinge repair, not just a new lock. If the building has multiple doors, it is worth thinking about the whole door plan, and our commercial locksmith work covers that bigger picture.

Call (213) 577-1366Commercial door hardware in Lake Balboa: what we see locally
Lake Balboa is ZIP code 91406, and we work across it, from the Balboa Boulevard and Victory Boulevard corridors to Sherman Way and Vanowen Street, around the Birmingham Charter High School area, and out toward the Sepulveda Basin edge near Anthony C. Beilenson Park. Our storefront is in Westwood, about 13 miles away, and our mobile vans come to you.
One scenario we see in this part of the Valley is lock service for small aviation businesses and offices on the west side of Van Nuys Airport. Those doors serve a business, so a latch that won't catch or a lock that won't turn can leave a building open or leave staff unable to secure it at close. We repair the hardware on site so the door works properly again.
Climate plays a part too. Lake Balboa sits on the Valley floor with hot, dry summers, and the air is somewhat damper near the irrigated parkland and lake by the basin. That seasonal swing causes modest sticking and alignment trouble in older wood doors, which is often when a latch that worked in winter stops catching in summer. If your commercial space is in an older building, its hardware may also be original-era. We confirm what's on the door in person and match or upgrade it.
Lake Balboa also has many apartment buildings along Sherman Way and Victory Boulevard. If you're locked out of a unit rather than dealing with a failing business door, that's apartment lockout service.
Why call Wilshire Lock & Key
We've been in business since 1987 and serve 140 cities across Los Angeles and Ventura counties. We have a real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans, so there's an actual shop behind the van that shows up.
When you call, you reach us, not a national call center that sells your job to whoever picks it up. One company handles the call, the visit, and the repair, with no dispatch middlemen. David, the owner and lead technician, oversees the work.
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith who comes to your door for it, and check it with the state if you want to. It's a reasonable question and a good habit.
Our phone is answered 24 hours a day, seven days a week, year-round: (213) 577-1366.
When the problem isn't the hardware
Sometimes a door problem is really a different job. If you can't get into your own business, that's business lockout. If you want to control who comes and goes, access control installation is the right conversation, and if you need many doors keyed under one hierarchy, look at a master key system. Tell us what's happening and we'll point you to the right fix, even if it isn't the one you called about.
Frequently asked questions
My commercial door only latches if I slam it. What's wrong?
That usually means the latch and strike aren't lined up, the door has sagged on worn hinges, or the closer isn't bringing the door in fully. Slamming makes it worse over time. We check each of those and fix the actual cause.
Can you fix a door that won't lock without replacing the whole lock?
Often, yes. A worn cylinder, a loose strike, a broken spring, or a rebuildable mortise case can be repaired. We tell you honestly when a lock is too worn to be worth fixing, and replacement makes more sense.
Do you handle warehouse and office doors in Lake Balboa?
Yes. We handle office door lock repair and warehouse door lock repair, including personnel doors, storerooms, and entrances. Warehouse doors usually need sturdier hardware and reinforced strikes because of heavy use and impact.
Is a commercial door that won't latch a safety or code problem?
It can be. Fire-rated doors are meant to close and latch on their own, and exit doors must open from the inside. We never defeat a latch to make things easier. If you're unsure of your requirements, check with your building owner or the local fire authority.
How much does commercial door hardware repair cost?
It depends on whether the fix is an adjustment, repair, or replacement, the grade of hardware, parts availability, the condition of the door and frame, and the number of doors. We explain the cost for your door before we begin.
Do you come to Lake Balboa at night or on weekends?
Yes. Our phone is answered 24 hours a day, every day of the year, at (213) 577-1366. Our storefront is in Westwood and our mobile vans serve Lake Balboa, including ZIP 91406 and the main boulevards.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask for the number and verify it with the state. Also ask whether the company has a real address and who will actually do the work.
My building is old and the lock has an odd mortise cutout. Can you replace it?
Often we can match or adapt older mortise hardware, but we confirm in person. We look at the door, the cutout, and the existing lock to see whether a matching body is available or a different solution is needed.
