Why does a commercial door stop latching or locking?
A commercial door does far more work than a house door. An office entry or a warehouse side door can be opened and slammed many times a day by people who are not thinking about the hardware. Over months and years, that traffic loosens screws, wears the latch, stretches springs and slowly shifts the door in its frame. Then one morning the door swings shut and does not catch, or the key turns and nothing happens.
The most common mistake we see is assuming the lock itself has failed. Often it has not. The door has dropped a little on its hinges, or the closer is slamming it, or the strike plate is a few millimeters off from where the latch bolt lands. Replacing a good lock does not fix a door that has moved, so we look at the whole opening before we recommend anything.
These are the usual causes behind a commercial door that won't latch or won't lock:
- Strike plate misalignment from a sagging door, worn hinges or a settled frame
- A worn or broken latch bolt that no longer springs fully out
- A mortise lock case with worn or broken internal parts, so the lever turns but the bolt does not move
- Loose, cracked or stripped lever trim, where the handle spins without moving the latch
- A door closer that is too strong, too weak or has lost its adjustment, so the door never reaches the latch fully
- Paint, dirt or debris packed into the strike or latch pocket
- A cylinder that has worn out or seized, so the key will not turn or will not come out
- Frame or door damage from a forced entry attempt, a cart impact or a forklift bump
How do we handle a commercial door repair, step by step?
Every call starts with a phone conversation, because the first few questions decide what we bring in the van. When you call (213) 577-1366, a person answers at any hour, and we work through the situation with you before anyone drives out.
- Tell us what the door is doing: won't latch, won't lock, key won't turn, handle spins loose, or the door won't stay shut. Tell us whether it is wood, hollow metal or an aluminum storefront door, and whether the building can be secured right now.
- If the door cannot be locked and the building is exposed, we talk through securing it first. Getting the space safe comes before a tidy repair.
- On arrival we test the door open and closed. We check the hinges, the closer, the gap around the frame, and where the latch lands against the strike.
- If the parts are sound, we repair: realign or adjust the strike, tighten or replace hinges, replace a worn latch or spring, or rebuild the lock case where that makes sense.
- If the hardware is worn out, we replace it and match the function the door needs, such as a storeroom, office or entrance function, along with the right backset, faceplate and finish for the existing door preparation.
- We cycle the door many times, run the key through the lock, check that it closes and latches on its own, and confirm that every key you hand us still works.
- Before we leave, we tell you plainly what else we noticed, such as a worn closer or a loose frame, so nothing surprises you next month.

Call (213) 577-1366What door hardware do we repair and replace?
Commercial door hardware covers more than a lock. A door that behaves badly is usually a small system with several parts that have to agree with each other. Here is what we work on under this service, and where a related page covers a topic in more depth.
- Mortise lock bodies, the heavy lock cases set into the edge of a door, common on older commercial wood and steel doors
- Cylindrical and heavy-duty lever locks used on office and tenant doors
- Latch bolts, deadlatches, strike plates and strike boxes
- Lever trim, knobs, escutcheons and thumbturns
- Hinges, including worn or sagging hinges that are the real cause of a latch problem
- Exit devices on exit doors; for new or replacement bars, see our panic bar installation page
- Closers that control how a door swings and latches; if the closer is the whole problem, our door closer repair page covers that work
- Glass storefront door locks and hardware, covered in more detail on our storefront lock repair page
Office door lock repair or warehouse door lock repair: what changes?
The hardware is similar in principle, but the way each door fails is different, and so is how we approach it.
Office doors tend to fail from age and from key sprawl. Interior office doors, suite entries and conference room doors usually see steady, moderate use. We often find lever sets that have loosened over time, cylinders that have been swapped by past tenants, and doors that no longer match the keying plan. In converted or reworked office space, we also see hardware that was never quite right for the door it was installed on. When an office door lock repair turns into a question of who holds which key, that becomes a keying conversation, and our master key system page covers it.
Warehouse doors take more physical abuse. Steel personnel doors, rear doors and loading-area side doors get bumped by carts and pallets, left propped open, and slammed in a hurry. Dust and grit get into latches. Frames get dented, which pushes the strike out of line. Warehouse door lock repair is often as much about the frame and hinges as the lock, and a heavier-duty lock case or a reinforced strike may be the right answer instead of repeating a light repair.
One honest boundary: if the trouble is with an overhead door's springs, track or opener, that belongs to a garage and overhead door company. We handle the locks, latches and hardware on the personnel doors and entries around it.

Call (213) 577-1366What affects the cost of commercial door hardware work?
We do not quote numbers on a web page, because commercial doors vary too much for a figure to mean anything. What we can do is tell you exactly what moves the cost up or down, so you can judge any quote you receive, ours included.
The biggest factor is whether the existing hardware can be repaired or has to be replaced. Realigning a strike, tightening a loose lever or replacing a single worn latch is usually the more economical route. A mortise lock case that has worn out internally may justify replacement, and the cost then depends on the lock's grade, finish and function.
Other things that shape the price:
- The door and frame material: wood, hollow metal, or aluminum storefront, each with different prep and parts
- The lock type and grade, and whether the exact replacement part is still available for an older lock
- Whether the door has been damaged and needs frame or door work in addition to hardware
- How many doors are involved, since several doors in one visit are handled more efficiently than separate trips
- Whether keys need to be matched to an existing system or re-keyed to a new plan
- The time of day: after-hours and weekend calls take more of our resources than a scheduled daytime visit
- How much the building needs to be secured temporarily if the repair cannot be finished on the first visit
What does commercial door hardware look like across El Segundo?
El Segundo is two quite different places for door hardware. The residential west side is a compact grid of older homes and low-rise apartments. The east side is almost entirely aerospace, media and office campuses with little housing. That east-side character is where most of our commercial hardware work sits, in service for campuses and office buildings, including areas like Continental Park and Campus El Segundo.
In Downtown El Segundo along Main Street, the work is storefront doors: lock service for shop and office entries where the door is used all day and locked at close. A door that won't latch at closing time is a real problem on Main Street, because you cannot walk away from it. For stubborn glass-door issues, the storefront lock repair page goes into detail, and a lockout at a business has its own page on business lockouts.
Smoky Hollow is a different case. Converted creative offices often mix older building shells with newer tenant improvements, so the doors and hardware do not always match. A lock change or hardware swap there can mean fitting modern levers into older door preparations, or sorting out which tenant holds which keys. The same applies around Plaza El Segundo and The Point retail district, where shop doors see constant daily use and a failed latch needs a quick, tidy fix.
El Segundo's ZIP code, 90245, spans all of these. Everything from a Main Street storefront to an east-side office building falls under the same service area for us.
The coast also plays a part. Marine layer and salt air corrode exterior locks, hinges and gate hardware on the west-side properties closest to the beach, while the inland office campuses see milder exposure. So on a campus door we would expect heavy use to be the bigger cause of wear, and on an exterior door near the coast we look at corrosion first. Either way we check which one we are dealing with before choosing parts.

Call (213) 577-1366Why call Wilshire Lock & Key for a commercial door problem?
We have been in business since 1987, and that history matters on this kind of work. Older commercial hardware, such as mortise locks, heavy lever sets and long-discontinued strikes, is something we have handled for decades, and we know how to repair a part rather than replace everything just because it is old.
We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties, El Segundo among them. You are dealing with one company, not a call center that passes your job to whichever contractor picks it up. The person on the phone is with the same company that sends the technician.
David, the owner and lead technician, oversees the work. When a job is unusual, such as an old mortise body with no listed replacement, that is the kind of problem that gets his attention.
We answer the phone 24 hours a day, 7 days a week, year-round at (213) 577-1366. If a door will not lock at night, you should not have to wait for business hours to talk to somebody. For after-hours problems more broadly, see our 24-hour locksmith page.
What should you ask any commercial locksmith before they start?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), called a Locksmith Company (LCO) license. Ask any locksmith for that license number before work begins, including us. It is a reasonable question and a good company will not mind it.
Beyond that, ask whether they plan to repair or replace and why, what is included in the quote, and whether keys will be cut or matched as part of the job. Be wary of anyone who proposes replacing every lock before even looking at the door, because the cause is very often alignment, a worn latch or a failing closer.
If you are managing several doors, an access system or a larger property, our commercial locksmith page gives the wider picture. If you are weighing electronic control for the doors we repair, the access control installation page explains how that fits with mechanical hardware.
Frequently asked questions
My commercial door won't latch. Do I need a new lock?
Not necessarily. Many doors that won't latch have a misaligned strike, worn hinges or a closer that has lost its adjustment. We check the whole opening first, and replace the lock only if the latch or lock body itself is worn out. Repair is often the more economical route.
What if my commercial door won't lock at night and I can't leave the building open?
Call (213) 577-1366 at any hour. We answer around the clock. Tell us what the door is doing and we will talk through how to secure the space, then send a van to fix or replace the hardware so the door locks properly.
Can you repair an older mortise lock, or does it have to be replaced?
Often we can repair it. Mortise lock bodies are built to be serviced, and we have worked on them since 1987. If internal parts are broken or the case is worn beyond use, we will explain why replacement is the better choice and what that involves before we start.
Do you handle office door lock repair for just one door?
Yes. A single office door, a suite entry or a conference room door is a normal job. If we find the same problem on other doors, such as loose levers or worn cylinders, we will mention it, but we only do the work you ask for.
Can you fix a warehouse door lock if the frame is damaged?
Usually, yes, for the lock side of the problem. A dented frame often pushes the strike out of line, and we can reinforce or reposition the strike and hardware. Serious frame damage may need a door or carpentry contractor, and we will tell you if that is the case.
How do you decide what a commercial door repair will cost?
It depends on whether we repair or replace, the door and frame material, the grade and availability of the lock, how many doors are involved, and whether the work happens after hours. We explain these factors on the phone and give you a clear quote once we see the door.
Will the new hardware work with my existing keys?
It can. Where possible we match replacement cylinders or locks to your current keying so staff do not need new keys. If your keys are scattered or unknown, that is a good time to re-key or set up a proper plan, which we can discuss when we see the door.
Is the problem my lock or my door closer?
Either can be the cause, and sometimes both. If the door is slamming, swinging back slowly, or stopping short of the latch, the closer is a likely suspect. We test the door with and without the closer's influence to tell which part is at fault.
Do you serve both Main Street shops and east-side office campuses in El Segundo?
Yes. We work on storefront doors in Downtown El Segundo, office doors in places like Smoky Hollow, and hardware on east-side office and campus buildings. Call (213) 577-1366 and tell us the type of door, and we will go from there.
