Commercial Door Hardware in Tarzana, CA: Mortise Locks, Latches and Doors That Won't Latch

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 the edge of the door instead of the handle. The lock is often fine. What changed is the door, the frame, or one worn part inside the lock body. Heavy steel and solid-core doors sag a little on their hinges after years of daily traffic. A latch that cleared the strike plate with room to spare when the door was new may now catch the lip of the plate or miss the opening entirely.

These are the causes we find most often, roughly in the order we find them:

Telling us which symptom you have helps, because the two repairs differ. A door that swings shut but never catches is usually an alignment, latch, or closer problem. A door that latches but won't lock is usually the deadbolt or the cylinder, or a deadbolt that now hits the frame because the door has moved. If you describe it on the phone, we know what to look at first.

One thing not to do: don't tape the latch, wedge the door, or force the key. Taped latches leave a business unsecured overnight, and forcing a worn cylinder often turns a repair into a replacement. If you cannot secure the door or you are locked out, see our page on business lockouts or just call.

• Door sag from worn hinges or loose hinge screws, so the latch no longer lines up with the strike
• A strike plate that has shifted, bent, or been scraped by a dragging latch for years
• A worn or broken latch bolt or spring inside a mortise lock case, so the bolt doesn't return fully
• A door closer set too weak to pull the door home against the latch, or so strong it slams and batters the hardware
• A worn cylinder cam or tailpiece, so the key turns but the bolt doesn't move
• Dirt, paint, or corrosion in the latch path, common on exterior doors
• Loose levers, trim, or spindles, so the handle turns but nothing happens inside the door

What commercial door hardware do we repair and replace?

Most of our commercial door repair work starts with the mortise lock. A mortise lock sits in a deep pocket cut into the edge of the door. The case holds the latch bolt, the deadbolt, the springs, and the gears, and the cylinder and lever trim connect to it. They are built for heavy use, and they are serviceable: in many cases a worn spring, cylinder, or trim can be replaced without swapping the whole lock.

Here is the range of commercial door hardware we work on:

Exit devices, door closers, and electronic access are their own jobs with their own parts. When your problem is really one of those, we point you to the right page rather than stretch this one: panic bar installation, door closer repair, and access control installation.

• Mortise lock cases, cylinders, and lever or knob trim
• Cylindrical (bored) leversets used on many office and interior doors
• Rim and surface-mounted locks on steel back doors and warehouse personnel doors
• Strike plates, latch guards, and the frame preparation behind them
• Hinges and pivots, including re-securing or replacing the ones that let a door sag
• Office, storeroom, and classroom-style function locks, where the inside and outside handles behave differently

How does a commercial door hardware repair go, step by step?

We work the same way on every commercial door, because the order matters. Diagnosing the door before touching the lock saves you from paying for a new lock that fails the same way a week later.

1. You call (213) 577-1366, any hour. We ask which door it is, what it does, what kind of hardware is on it, whether it is steel, wood, or aluminum-and-glass, and whether it is an exit door or fire-rated. We also ask whether the building is secure right now.
2. If the opening can't be secured, that comes first. Everything else can wait until the door holds.
3. On site, we check the door before the lock: how it swings, the gaps around it, the hinges, the closer, and exactly where the latch meets the strike.
4. We fix the cause upstream. That might be tightening or replacing hinge screws, repositioning a strike, or adjusting the closer. In many cases the lock itself never needs to come out.
5. If the lock is the problem, we pull it, open the case where it is serviceable, and test the parts. We replace what is worn, or the whole lock body if the lock has reached the end of its life.
6. We test the door open and closed, from both sides, with every key, repeatedly, and with the door allowed to swing shut on its own the way it does at 6 a.m. when the first person walks in.
7. We walk you through what failed, what we changed, and what to watch. If the cause was something like a worn door that will keep sagging, we say so.

Repair or replace: how do we decide?

We lean toward repair when the lock body is sound and the problem is alignment or a replaceable part. A sagging door with a perfectly good mortise lock is a hinge and strike job, not a lock job. We lean toward replacement when the case is worn through, parts for an old model are no longer available, or the hardware was never right for the door. A light-duty residential lockset on a busy commercial entry will fail again, and we would rather tell you that than keep patching it.

When we replace a mortise lock, we try to match the existing door preparation so the new case drops into the same pocket without recutting the door. That is often possible but not always, and we confirm it in person before promising it.

Two cautions apply to any commercial door. First, a fire-rated door depends on closing and latching every time. We don't remove latches or set up doors to be held open, and any hardware swap on a rated door needs to be appropriate for that door. Check for a label on the door edge or frame, and tell us if you see one. Second, in an occupied building, people generally need to be able to leave through an exit door without a key. If you're unsure what your building requires, your landlord, property manager, or the local fire authority can say, and we will work within that.

What affects the cost of commercial door repair?

We don't quote numbers on a web page, because the same symptom can be a small adjustment or a full lock replacement, and nobody can tell which from a description of a stuck door. Here is what actually moves the cost:

The honest way to get a number is to describe the door on the phone and then have us look at it. If a part must be ordered or the door needs more than hardware work, we say that before starting.

• Whether the fix is an adjustment (hinges, strike, closer) or a part replacement
• Whether the lock case is serviceable or has to be replaced entirely
• The grade and type of hardware, and whether it is a common model or an older or specialty one
• Finish and function matching, such as keeping the same lever style or office function across several doors
• Fire-rating and exit requirements, which limit what can be installed
• The condition of the door and frame, since a damaged door edge or frame can add work
• How many doors are involved, and whether keys need to stay compatible with an existing system
• The hour of the call, since after-hours and emergency work is different from a scheduled visit

What do we see with commercial door hardware around Tarzana?

Tarzana's commercial doors cluster in a few distinct areas, and the hardware problems differ between them. Along the Ventura Boulevard corridor and the Tarzana Safari Walk business district, storefront and small-office doors open and close all day. A latch that is slightly out of line takes the daily punishment first, and glass-and-aluminum entries tend to show it as a door that needs a shove to catch. For the storefront side of this, see our page on storefront lock repair.

Around the Tarzana medical district near Providence Cedars-Sinai Tarzana Medical Center, suite entries, supply rooms, and records rooms depend on office and storeroom-function locks that get cycled constantly. A latch that sticks or a storeroom lock that no longer locks is a hardware problem to fix quickly, not live with. In the North Tarzana flats along Victory and Vanowen, steel back doors and rim hardware are the kind of thing we look at, where heat, dust, and daily use wear on latches and strikes.

The climate matters too. Valley summers are hot, and the foothills south of Ventura add sun and canyon wind exposure. Exterior locks and gate hardware on hillside and equestrian properties weather faster than protected entries. When we check a stubborn exterior door in 91356, we look for sun-baked finish, gummed-up latches, and a door that binds more in the afternoon heat than it does in the morning.

Guard-gated communities off upper Reseda Boulevard, such as Mulholland Park and Braemar Estates, are mostly a gate-hardware matter rather than door hardware. If your issue is a gate latch or pedestrian gate lock, gate lock repair is the page for it. Tarzana is about 14 miles from our Westwood storefront, and we come to you. If a part has to be ordered for an unusual lock, we tell you that on the call.

How do office, warehouse and storefront doors differ?

Office door lock repair is mostly about function. Interior office doors are often set so the inside lever always opens, the outside locks with a key, and the lock can be overridden by management. When one of those stops behaving, it is usually a worn spring or a cylinder, and a simple fix. If you have many office doors that all need to work on a shared key hierarchy, the system matters more than any single lock, and that is where a master key system comes in.

Warehouse door lock repair leans toward rugged: steel personnel doors, rim locks, heavy-duty strikes, and hardware that gets hit by carts, forklifts, and wind. The usual failures are bent strikes, damaged door edges, worn deadbolts, and closers that were never adjusted. These doors tend to be replaced less than repaired, because the door itself is sound and just needs the latch geometry back in order.

Storefronts combine both: public-facing, in constant use, and often with narrow aluminum stiles that limit what hardware fits. A lock that doesn't throw its bolt fully on a storefront door is a security problem at closing time, and we treat it that way. For wider business-security needs beyond one door, our commercial locksmith page covers the bigger picture.

Why call Wilshire Lock & Key for commercial door hardware?

We've been in business since 1987, and a lot of that time has gone into commercial doors: figuring out why a latch that looks fine won't catch, and fixing the door instead of selling a new lock. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties, so Tarzana is routine work for us.

When you call (213) 577-1366, the phone is answered 24 hours a day, seven days a week, year-round. It is one company, not a dispatch middleman passing your call to whoever is closest. David, the owner and lead technician, oversees the work. You get a plain explanation of what's wrong, what we recommend, and what the lighter-cost option is when there is one, usually the repair rather than a replacement.

Being honest also means telling you what we can't do. If a door is dealer-only hardware, a proprietary system, or needs a part we have to order, we will say so up front and not guess.

How do I choose a locksmith for commercial door work?

California requires locksmith companies to hold a BSIS LCO license, which is the Bureau of Security and Investigative Services company license. Ask any locksmith who quotes you commercial work for the license number, and verify it with the state before work begins. It matters more on commercial doors, because the hardware protects your inventory, your records, and your staff.

Beyond the license, ask a few practical questions. Will they diagnose the door before quoting a new lock? Will they tell you the difference between a repair and a replacement? Will they explain the fire-rating and exit-door issues? A good tradesperson answers these without hurry. If a company quotes a full replacement over the phone without hearing what the door is doing, that is a reason to keep asking questions.
