Why does a commercial door stop latching or locking?
A commercial door that will not latch is almost never a mystery once someone puts hands on it. The cause is usually one of a handful of things: the latch bolt is worn or sticking inside the case, the strike plate no longer lines up with the bolt, the door has dropped on its hinges, the closer is no longer pulling the door fully shut, or the mortise lock body has failed internally. Each of those looks the same from the outside. The door sits a quarter inch proud of the frame, or it bounces back open, or the key turns but nothing happens.
A door that will not lock is a slightly different problem, but it often has the same roots. A cylinder can wear until the cam no longer engages. A deadbolt throw can bind against a misaligned strike. A trim or spindle can strip so the handle turns freely without moving the latch. And sometimes the lock itself is fine and the door has simply moved, because buildings settle, hinges loosen, and wood and metal frames shift with temperature.
The reason this matters more on a commercial door than a residential one is simple: you cannot just shut the shop and go home with a door that does not secure. Someone has to fix it, or stay with it, or you accept the risk overnight. Our job is to work out which of these causes you have, fix that cause, and not sell you hardware you do not need.
What commercial door hardware problems do we repair?
Commercial door hardware covers more than the lock itself. It is the whole set of parts that lets a door close, latch, lock, and open again reliably under heavy daily use. We work on the following, among other things:
- Mortise locks that are stuck, worn, or no longer throwing the latch or deadbolt, including older bodies on legacy storefront doors
- Cylindrical and heavy-duty lever sets in offices, clinics, and retail back rooms
- Latches that hang up, retract slowly, or fail to catch in the strike
- Strike plates and door frames that have shifted out of alignment
- Exit devices and panic hardware that will not dog, latch, or release properly
- Door closers that slam, drift, or stop short of the latch, which then gets blamed for a lock problem
- Office door lock repair for interior doors, including keyed entry, storeroom, and privacy functions
- Warehouse door lock repair on steel personnel doors, roll-up service entries, and gated yards
- Worn or snapped keys, damaged cylinders, and stripped trim or spindles

Call (213) 577-1366How do we handle a commercial door hardware call?
Every job is a little different, but the sequence is consistent. We would rather diagnose properly than swap parts and hope.
- You call (213) 577-1366. A person answers at any hour, and we ask what the door is doing: will not latch, will not lock, key turns freely, handle is loose, door swings back open, or something else.
- We ask what kind of door and hardware it is: wood, hollow metal, or aluminum storefront; mortise or cylindrical; whether there is a closer or panic device; and roughly how old the hardware looks. Photos help if you can send them.
- A mobile van comes to your location. On arrival we check the door before the lock: how it hangs, whether it closes on its own, where the bolt meets the strike, and whether the frame has moved.
- We test the hardware itself. That means operating the latch and deadbolt with the door open, looking for binding, broken springs, stripped parts, or a worn cylinder.
- We explain what we found in plain terms and give you the realistic options: adjust, repair, rebuild, or replace. If a simple alignment fixes it, we say so and do that.
- We do the work, then test the door repeatedly, open and closed, locked and unlocked, from both sides, before we hand it back. If the door has to be secured and a part is not on the van, we make it secure for the night and tell you what comes next.
Repair or replace: how do we decide?
Commercial hardware is built to be serviced, which is why repair is often a reasonable answer. A mortise lock body from a reputable maker can frequently be rebuilt or have worn internals swapped, and a strike can be adjusted or repositioned in a few minutes. On an older storefront door, keeping the original hardware can also keep the look of the building intact.
Replacement makes more sense in a few situations. The first is when the parts are worn through and the repair would only buy a short stretch of reliability. The second is when parts for an old or discontinued lock are no longer realistically available. The third is when the hardware no longer matches what the door needs, for example when a business has changed how it uses a space and now needs a different function, a storeroom lock instead of an office lock, or an exit device to meet how people leave the building.
We will tell you which path we would take and why. If you want a second opinion on a quote you already have, we are happy to look at the door. For standalone lock work that is not tied to a commercial door, our lock repair page covers that side.

Call (213) 577-1366What affects the cost of commercial door repair?
We do not publish numbers here, because the honest answer depends on the door in front of us. What we can do is explain what moves the cost up or down, so you can judge any estimate you receive, ours included.
The biggest factor is whether the problem is adjustment, repair, or replacement. Re-aligning a strike or tightening a door is a lighter-cost job than rebuilding a mortise body, and that is usually lighter-cost than replacing the full hardware set on a door.
- The type of hardware: a standard cylindrical lever is simpler than a mortise lock, and an exit device or a high-security cylinder is more involved than either
- Whether the door or frame itself needs work, such as hinge repair, a dropped door, or a damaged frame where the strike mounts
- Availability of parts, especially for older or discontinued mortise bodies
- The number of doors: several doors in one visit are more efficient than a return trip for each
- Whether keys need to be matched, rekeyed, or set up on a master key system
- The hour of the call: after-hours and urgent work involves a different level of effort than a scheduled daytime visit
- Your location and the travel involved from our base
What does door hardware look like in San Dimas?
San Dimas is mostly 1960s through 1980s suburban tracts, but the commercial side has its own character. Downtown San Dimas, around the Bonita Avenue district, is western-themed and holds older storefronts, and older storefronts often carry legacy commercial hardware. That can mean mortise locks and latches that have been in service for decades, with worn cases, loose trim, and strikes that no longer sit where the bolt lands. Those are the kinds of calls where repair and rebuilding are worth a serious look before replacement is considered. If a storefront door is the main issue, our storefront lock repair page goes deeper on that style of door.
Commercial space also runs along the Lone Hill Avenue corridor, the Foothill Boulevard (Route 66) corridor, and the Arrow Highway corridor, all within ZIP code 91773. Along those streets you find offices, retail suites, and service businesses with a mix of hardware generations. A shop that has changed tenants a few times may have a front door with one brand of lock, a back door with another, and a closer that nobody has adjusted in years.
Heat is the other local factor. San Dimas sits inland, where summer highs run well above the coastal basin. Late-summer door expansion and sticking latches are routine here. A door that closes cleanly in March can rub the frame and refuse to latch in August, and the lock often takes the blame when the real fix is an adjustment at the hinge, strike, or closer. Canyon winds also carry dust into exterior hardware, which can gum up latches and cylinders on doors that face open exposure. A cleaning and proper lubrication of the right kind, not a spray of whatever is in the garage, often restores a sticky latch before anything needs replacing.
Because the city sits about 40 miles from our Westwood base, we plan San Dimas visits carefully and bring the parts we expect to need for the type of door you describe. Telling us the make of the lock, if you can read it off the faceplate, helps us arrive prepared.

Call (213) 577-1366Which doors do businesses call us about most?
Here are some common situations we are asked to handle, described generally rather than as specific past jobs.
- A front door that has to be lifted or pulled hard to latch, usually a dropped door or a strike that has drifted
- A back-room or storeroom door that will not lock because the bolt no longer extends fully
- An office door where the key turns but the latch stays put, often a stripped spindle or broken latch spring
- A warehouse personnel door that swings back open after closing, frequently a closer problem rather than a lock problem
- An exit device that sticks, will not dog, or does not retract smoothly, where our panic bar installation and door closer repair pages describe related work
- A lock that works but whose keys have multiplied beyond control, where a master key system may be the better long-term answer
Why call Wilshire Lock & Key for commercial door hardware?
We have been in business since 1987. That is long enough to have seen a lot of old mortise hardware, and to know which problems are a quick fix and which are a sign the part is finished. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so we are a real place with real people, not a call center passing your job along.
When you call (213) 577-1366, you are dealing with one company. There is no dispatch middleman who sends a stranger and takes a cut. The person who answers is part of the operation that does the work. David, the owner and lead technician, oversees the work, which means there is someone accountable for how a job is done.
We answer 24 hours a day, 7 days a week, all year, because doors do not fail on a schedule. If your door will not secure at night, call. If the problem is a lockout rather than a hardware failure, our business lockout service is the better starting point. For broader needs across an office, shop, or warehouse, see our commercial locksmith overview.
What should you ask any locksmith before they start work?
California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Ask any locksmith you are considering for that license information. A legitimate company will give it to you without hesitation.
Also ask for a clear description of the work before it begins, what is being repaired or replaced and why, and what could change the scope once the door is open. A good technician explains the problem in terms you can follow and shows you the worn part when there is one.
If you are thinking beyond a single repair, such as controlling who can open which doors, our access control installation page explains that option. For any other questions about your property or a visit, you can reach us through the contact page or see everything we offer in San Dimas on our San Dimas locksmith page.
Frequently asked questions
Why won't my commercial door latch all the way?
The usual causes are a strike plate that no longer lines up with the bolt, a door that has dropped on its hinges, a closer that stops short, or a worn latch inside the lock. In San Dimas summers, heat can also make a door expand and rub the frame. We check alignment and the closer before touching the lock, because that is often the real fix.
My commercial door won't lock even though the key goes in. What is wrong?
If the key turns but the bolt does not move, the cylinder cam, the spindle, or the lock body may be worn or broken. If the bolt moves but will not fully extend, the strike is often out of line. We test the hardware with the door open to tell which it is, then repair or replace only what has actually failed.
Can you fix an old mortise lock, or does it have to be replaced?
Often it can be repaired or rebuilt, especially on older storefront doors where keeping the original hardware matters. Replacement makes sense when the parts are worn through, no longer available, or the lock no longer suits how the door is used. We tell you which option we would choose and why.
Do you handle office door lock repair and warehouse door lock repair?
Yes. Office doors, storerooms, warehouse personnel doors, and back entrances all use commercial hardware we work on. Tell us the type of door and what it is doing, and we plan the visit around that. For roll-up or gate hardware beyond a standard door, we confirm what is involved when you call.
Do you come out at night or on weekends for a commercial door that will not secure?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. If a door cannot be fully repaired that night, we make it secure and explain what remains to be done.
How much will a commercial door repair cost?
It depends on the work, not on a flat rate. A strike adjustment is lighter-cost than rebuilding a mortise lock, and rebuilding is usually more economical than replacing a full hardware set. Parts availability, the number of doors, door or frame damage, key requirements, and the hour of the call all affect the final figure. We explain the options before work begins.
Is a door closer problem the same as a lock problem?
No, but they often get confused. If a door swings back open or does not close fully, the latch never gets a chance to catch. We look at the closer first. If that is the cause, our door closer repair service covers it.
What should I check before I call about a commercial door that won't latch?
Look at whether the door closes by itself and where the bolt meets the strike. Note any rubbing at the frame, loose hinges, or dust packed into the latch. Then read the maker's name on the lock faceplate if you can. None of this is required, but it helps us bring the right parts to your San Dimas address.
