What counts as commercial door hardware?
Commercial door hardware is everything on a business door that holds it shut, lets people through, and keeps it secure: the mortise lock or lockset, the latch and strike, the lever or knob, the hinges, the closer, any exit device, and the cylinder that takes the key. These parts are heavier and built for far more cycles than the ones on a house door, because the front door of a shop or office can open hundreds of times in a day.
Most calls we get fall into a few buckets. The door won't latch. The door won't lock. The key turns but nothing happens. The lever spins loose in your hand. Or the door has started to drag, stick, or slam. Nearly all of these can be fixed without replacing the whole door, and plenty can be fixed without replacing the lock either. The skill is working out which part is actually failing before anybody starts swapping things out.
This page covers the hardware on the door itself. If you are locked out of your own business, that is a different job, and our business lockout service is the right place to start.
Why won't my commercial door latch?
A commercial door that won't latch is almost never a mystery once someone looks at it with the door open and then closed. The latch bolt is supposed to meet the strike opening cleanly. When it doesn't, something has moved, worn, or broken. The usual suspects, roughly in the order we check them:
- The door has sagged on its hinges, so the latch bolt lands above or below the strike opening and catches on the plate instead of the pocket.
- The strike plate has loosened or shifted, or the frame behind it has been knocked out of true.
- The latch bolt or the spring inside the mortise body is worn, sticky, or broken, so the bolt doesn't extend fully.
- The door closer is failing or set wrong, so the door drifts shut instead of closing with enough push to engage the latch. A weak closer is a common reason people think the lock itself is bad, and our door closer repair page covers that side.
- The lever trim has come loose from the spindle, so turning the handle no longer moves the latch the way it should.
- Paint, grit, or debris has built up in the strike pocket and keeps the bolt from seating.
- On older wood doors, summer heat can swell the door just enough that it rubs the frame and stops short of the strike.

Latching and locking are two different jobs, and a door can do one without the other. If the door closes but the key won't lock it, or the deadbolt turns freely without throwing, the problem is in a different set of parts than a latch that won't catch.
The common causes are a worn cylinder where the pins no longer respond to the key, a broken cam or tailpiece behind the cylinder that turns without moving the bolt, a bolt that throws but can't reach the strike because the door has shifted, and internal wear in an old mortise body. Sometimes the key itself is the culprit, especially a copy of a copy that has worn down over years of use.
Sometimes the lock is fine and the real issue is who holds keys. If a former employee, tenant, or contractor still has a working key, repairing the lock won't fix that, and rekeying the locks is usually the more economical route compared with replacing every piece of hardware.
How we repair a commercial door that won't latch or lock
We keep the process simple so you know what is happening at each point. Here is how a typical call goes:
- You call (213) 577-1366. A person answers, any hour of any day, and asks what the door is doing, what kind of door it is, and whether the building is open or has to be secured tonight.
- We send a mobile van to your location. Our storefront is in Westwood, about 20 miles from South Pasadena, and the vans are what we use for on-site work.
- We look at the whole opening, not just the lock. That means checking the hinges, the frame, the strike, the closer, and the latch with the door open and closed before we decide what is at fault.
- We tell you what we found in plain terms: what failed, why, and whether it makes sense to repair it or replace it. If it is cheaper and sound to adjust a strike or tighten hinges, we say so.
- We make the repair, which might be realigning a strike, replacing a latch or spring set, rebuilding or replacing a mortise body, or swapping a cylinder.
- We test it properly. The door gets cycled many times, locked and unlocked with the key from both sides, and closed without a push to confirm it latches on its own.
- We hand over the keys and explain what was changed, so whoever opens the shop tomorrow isn't guessing.

Call (213) 577-1366Repair or replace: what makes sense for a mortise lock?
Mortise locks are the workhorse of older commercial doors. The lock body sits in a pocket cut into the edge of the door, and the good ones can run for decades. That is also why they are often worth repairing. Springs, latch bolts, and cylinders are frequently replaceable without touching the rest of the door, and keeping the existing mortise body avoids cutting a new pocket.
Replacement makes more sense when the body is cracked, the internal parts are too worn to hold adjustment, parts for that older model can't be found, or the door needs a different function than it has now. We also look at whether the hardware still suits how the door is used. A door that serves as an exit path may need panic hardware, and our panic bar installation page explains that side. If the trouble is mainly at a shop front, the storefront lock repair page covers glass doors and the hardware that goes with them.
One thing we won't do is put in hardware that defeats a door's fire rating or exit requirements just to make the problem go away. If a door sits in a rated opening, the latch has to work every time, and we'll tell you if what you asked for doesn't fit.
What affects the cost of commercial door repair in South Pasadena?
We don't publish numbers on this page, because the honest answer depends on the door. Here is what moves the cost up or down:
- The type and grade of hardware. A heavy-duty mortise lock costs more to repair or replace than a light-duty cylindrical lockset.
- Whether the problem is the lock or the opening. Realigning a strike is a smaller job than rehanging a sagging door or repairing a damaged frame.
- Parts availability. Common mortise bodies are easy to source, while older or discontinued models can take more effort.
- Whether the new cylinder has to fit an existing key system. Matching a master key setup adds steps that a standalone door doesn't need.
- How many doors are involved. A single office door and a row of suite doors are different scopes.
- The time of day. Late-night and holiday work is a different kind of call than a weekday daytime visit.
- Security needs. A higher-security cylinder or a restricted keyway costs more than a standard one, and some businesses want that.
Office and warehouse door hardware: what's different?
Office door lock repair and warehouse door lock repair are both commercial work, but they fail in different ways. Office doors tend to be about daily use by many people with keys, and the problems are worn cylinders, loose levers, and keys that have been copied too many times. If an office has outgrown its keys, a master key system can bring order, and some offices decide to move to access control so they can stop tracking metal keys altogether.
Warehouse and back-of-house doors take more abuse. Steel doors get hit by carts and pallets, frames get bent, and exit hardware gets slammed thousands of times. When a warehouse door won't latch, the cause is often a frame that has been knocked out of square, and a new latch alone won't fix that. We check the frame first so you aren't paying for a part that will fail again on the next bump.
For a broader look at what we do for businesses, our commercial locksmith page lays out the full range.

Call (213) 577-1366Commercial door hardware around South Pasadena
South Pasadena is a small city with a mix of older buildings and newer ones, and the door hardware tends to reflect that. Around the Mission Street business district, near Mission Station on the Metro A Line, storefront lock service is the kind of call we expect: a shop door that has stopped latching after a busy week, or a cylinder that sticks when the owner closes up. The same goes for shops and offices along the Fair Oaks Avenue corridor and in the Mission West district, where older buildings can have older hardware that deserves repair before replacement.
The city is also known for preservation-minded homes from the 1890s to the 1930s, and some of that old-hardware character shows up in how people think about their buildings. If your business occupies an older space in 91030, there is a decent chance the lock on the door has been there a long time. We would rather rebuild a sound mortise lock than throw out something that still has years left.
Weather here is mild and inland, so locks aren't chewed up by coastal air the way they can be elsewhere. The thing to watch is summer heat, which can swell older wood doors and make them rub the frame, and that is a common reason a door suddenly won't latch in August when it did fine in March. On Raymond Hill, where apartments and condos cluster, shared building doors and commercial-style entry hardware also see steady use. Whichever part of town you're in, call (213) 577-1366 and we'll send a van.
Why call Wilshire Lock & Key for door hardware?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties. We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so the person who answers the phone works for the same company that sends the tech. There are no dispatch middlemen passing your call along to whoever is available.
David, the owner and lead technician, oversees the work. That matters on door hardware, because a lot of what separates a good repair from a bad one is judgment: seeing that a latch problem is really a sagging hinge, or that a mortise body is worth saving.
California requires locksmith companies to hold a Locksmith Company license through the Bureau of Security and Investigative Services (BSIS), known as an LCO license. Ask any locksmith for that license number before they start work. That is a reasonable thing to ask of us too, so ask when you call (213) 577-1366.

Call (213) 577-1366What to do before we arrive
If your door won't latch or lock and you are waiting on a visit, a few simple steps help us and protect your space:
- Don't force the key or kick the door. A stuck latch can usually be fixed, but a bent frame or snapped key makes the job bigger.
- Note which door it is and what it does: won't latch, won't lock, key spins, lever loose. That one sentence saves diagnosis time.
- If a key broke off in the lock, tell us when you call so we bring the right tools.
- If the business has to be secured overnight, say so. We can often make the door safe first and finish the full repair when it makes sense.
- Take a quick photo of the door, lock, and strike if you can. It helps us bring the right parts.
Frequently asked questions
Why does my office door only latch if I slam it?
Usually the latch bolt and strike aren't lined up, a door closer is too weak, or the door has sagged. Slamming works because it forces the bolt past the misalignment. It also wears the hardware faster, so it is better to have the opening adjusted than to keep slamming.
Can you repair a mortise lock, or does it have to be replaced?
Often it can be repaired. Springs, latch bolts, and cylinders are commonly replaceable without removing the whole body. Replacement makes sense when the body is cracked, worn out, or unavailable in parts. We look at it in person and tell you which route fits.
Do you handle warehouse door lock repair?
Yes. Warehouse and back-of-house doors take hard use, so we check the frame and hinges as well as the lock. Fixing only the latch on a bent frame leads to the same call again soon, so we address the cause.
Will you come out at night if my shop door won't lock in South Pasadena?
Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366, and our mobile vans work after hours. If the door can't be fully repaired that night, we focus on securing it first.
How do I find out what the repair will cost?
Cost depends on the type of hardware, whether the frame or hinges are involved, parts availability, the number of doors, and the time of day. We tell you what we found and what it will take before we begin, so you can decide with the facts in front of you.
Can you match our existing keys or key system?
In many cases yes, especially if a cylinder just needs replacing or rekeying. If your doors are part of a master key system, tell us up front so we can plan the work around it.
Is Wilshire Lock & Key a licensed company?
California requires locksmith companies to hold a BSIS Locksmith Company (LCO) license, and you should ask any locksmith for that number before work begins. That applies to us as well, so feel free to ask when you call (213) 577-1366.
How far are you from South Pasadena?
Our Westwood storefront is about 20 miles away, and our mobile vans serve 140 cities across Los Angeles and Ventura counties, South Pasadena included. Call (213) 577-1366 and we'll go over what is happening with your door.
