What counts as commercial door hardware, and what usually fails?
Commercial door hardware is everything on a business door that holds it shut, lets people through, and keeps it from slamming or hanging open. That means the mortise lock body or cylindrical lock, the latch bolt and deadbolt, the strike plate in the frame, the hinges, the closer, the lever handles or trim, any exit device, and the cylinders that take the keys. It is built heavier than what you find on a house door because it gets used far more. The front door of a busy shop can open and close hundreds of times in a day, and the parts wear to match.
When something fails, it rarely fails all at once. A latch starts to stick, then you have to lift the door or lean on it, and one morning it simply won't catch. A key turns stiffly for a month and then the cylinder seizes. The causes repeat, and most of them can be fixed without tearing out every piece of hardware on the door. This page covers the repair side: mortise locks, latches, strikes, levers, and doors that won't latch or won't lock. If you are already locked out of your own building, start with our business lockout service in North Hollywood instead.
Why won't my commercial door latch?
A commercial door that won't latch is the most common complaint in this category. The cause is usually mechanical and easy to find once someone looks at the whole door and not only the lock. These are the things we check first:
We would rather tell you the strike needs a small adjustment than sell you a new lock you don't need. If the closer turns out to be the real problem, that falls under door closer repair, and we will say so plainly instead of replacing a latch that was never broken.
- Strike plate misalignment: the latch bolt no longer lines up with the opening in the frame, often because the door has dropped a little on its hinges.
- Loose or worn hinges, which let the door sag so the bolt hits the edge of the plate instead of the hole.
- A worn, sticky, or dirty latch bolt whose spring can't push it all the way out.
- A closer that is too weak, or adjusted so the door stops just short of the frame and the latch never gets its final push.
- Weatherstripping, a threshold, or a door that has swollen or shifted and now drags.
- A failed mortise lock case or a broken internal spring, where the handle moves but the latch doesn't respond the way it should.

Call (213) 577-1366What if my commercial door won't lock?
A door that won't lock is a different problem from one that won't latch, and it is more urgent, because the building may be open to anyone overnight. The bolt might not be reaching the strike because the door and frame have moved out of line. The cylinder might be worn from years of keys, or damaged by a forced attempt. A broken cam or tailpiece can leave the key turning freely without moving the bolt, and a thumbturn can spin with nothing behind it. Loose trim and a handle that has pulled away from the door can do it as well.
If the door won't lock after a break-in attempt, we also look at the frame, because split wood or a bent steel jamb will defeat even new hardware. Our first job is to make the door secure, even if that is a temporary measure until the right part is in hand. If the real issue is that too many people hold keys, whether from a lost key, a former employee, or a tenant who left, repairing a lock that still works isn't the answer. A rekey is usually the more economical route, since it changes which keys work without replacing the hardware.
How does a commercial door hardware repair work, step by step?
Calls usually go the same way, whether the door is a glass storefront, a steel back door, or a wooden office door. The sequence matters because it keeps us from guessing.
- Call (213) 577-1366 at any hour. Tell us what kind of door it is, what the lock looks like if you can see a brand name, and what it is doing: sticking, not catching, spinning, or refusing the key.
- We send a mobile van carrying the commercial parts we use most often, or you can bring a lock or part to our storefront at 10740 Wilshire Blvd in Westwood if the door is portable.
- The technician looks at the door as a system: frame, hinges, closer, strike, latch, lock body, and cylinder. Most latch problems are really alignment problems, so we test before we replace.
- Before work begins, we explain what we found and what your options are, usually repair versus replace, and what is driving the cost of each.
- We do the work, then test the door open, closed, locked, and unlocked, from both sides, with every key you have.
- We leave the door secure and tell you honestly about anything we noticed that is still worth attention, such as a tired frame or a closer near the end of its life.

Call (213) 577-1366Office door lock repair and warehouse door lock repair: what is different?
The word commercial covers a lot of different doors, and the hardware problems differ by building type. Office door lock repair is mostly about daily wear and keying. Suite doors and interior offices often use lever sets that loosen over time, so the handle droops, the latch retracts only partway, or the key starts to stick. The fix is usually a tightened or replaced lever, a new latch, or a fresh cylinder.
Warehouse door lock repair is a different job. Back and side doors are often steel, they take knocks from carts and pallets, and they sit in dust and weather. Hardware gets bent, frames get dented, and a door that has been hit may only latch if you lift it. Heavier-duty latches, protected strike plates, and sometimes a reinforced frame are what hold up. To be clear about scope, this page covers personnel doors and their hardware, not overhead or dock doors.
- Office doors: loose levers, sticking keys, worn latches, and keying that no longer matches who should have access.
- Warehouse and back doors: impact damage, dented frames, dust in the mechanism, and doors that latch only when lifted.
- Storefront doors: heavy daily cycling, glass doors with narrow frames that limit which hardware fits, and tenant turnover that calls for new keying.
What affects the cost of commercial door repair?
We don't quote prices on a web page, because a commercial door can't be priced honestly without seeing it. A sticking latch that needs a strike adjustment is a very different job from a seized mortise case in a steel door. What moves the cost is fairly predictable:
- Repair or replacement: adjusting, cleaning, or swapping one part is usually the lighter-cost path, and a full replacement makes sense when the hardware is worn throughout.
- Lock type and grade: mortise locks, cylindrical locks, and heavy-duty grades differ in parts cost and in how long they take to service.
- Availability of parts: common commercial hardware is simple, while discontinued or specialty hardware may need to be sourced.
- Condition of the door and frame: a sagging door, bent jamb, or split wood can add work that has nothing to do with the lock itself.
- Number of doors and how they are keyed: several doors on one key system take more planning than a single office door.
- Timing: an urgent call at night is handled differently from a scheduled visit during the week.
- Added functions: exit devices, closers, or access control change the scope of the job.

Call (213) 577-1366Should I repair or replace commercial door hardware?
Repair is usually the first choice when the hardware is basically sound and the fault is alignment, a worn latch, a loose set, or a tired cylinder. Replace when the lock body is worn throughout, the parts are no longer available, or the door has been forced and the internals are damaged. Replacement also makes sense when the hardware no longer suits how the door is used, for instance a residential-grade lever on a door that gets constant traffic.
Some doors raise a safety question, not only a repair question. A door used as an exit may need hardware that opens easily from the inside without a key, and in that case we'll talk through panic bar installation as an option. We won't push an upgrade the door doesn't need, and we will tell you plainly if the existing hardware is a problem.
What does commercial door hardware repair look like around North Hollywood?
North Hollywood has a mix of doors, and the mix shapes the work. In the NoHo Arts District, theaters and small venues have doors that open for audiences and close behind them, so the hardware gets heavy use at predictable times. A latch that lags or a lock that sticks is a bigger problem when a crowd is arriving. Along the Lankershim Boulevard and Magnolia Boulevard corridors, storefronts change hands and tenants change, and a new tenant often wants the keying reset and the tired hardware looked at in the same visit. For that kind of work, our storefront lock repair page covers the details. The Valley Plaza area is another place where retail doors see steady cycling.
Climate matters too. North Hollywood sits in a flat interior valley with hot, dry summers, and heat-related expansion of doors and frames is the main seasonal factor for exterior doors. A door that latched fine in spring may start to bind or miss its strike in July, and that is often a matter of adjusting the strike or hinges, not buying a new lock. We check that first.
The area also has older multifamily buildings with shared-entry doors and intercom hardware, and newer mid-rise buildings near the North Hollywood Metro B/G Line Station. Entry doors in those buildings take commercial-style wear even though the building is residential. If a shared-entry door has stopped latching or the strike no longer seats, we can look at the hardware, and where the building wants something more controlled, we can talk about access control. We cover the 91601, 91602, 91605, and 91606 ZIP codes, and North Hollywood is one of many neighborhoods we reach with mobile locksmith service.

Frequently asked questions
My commercial door only latches if I slam it. Is it safe to leave that way?
Not for long. A door that needs force to latch is usually misaligned, sagging, or fighting a weak closer, and on the night it fails to latch, the building is open. It is usually a straightforward repair, so call (213) 577-1366 and we can look at the strike, hinges, closer, and latch together.
Can a mortise lock be repaired, or does it have to be replaced?
Often it can be repaired. Mortise locks are built to be serviced, and a worn spring, a sticking latch, or a bad cylinder can be replaced without changing the whole unit. If the case is badly worn, damaged by forced entry, or the parts are no longer available, replacement makes more sense. We confirm which applies after inspecting the lock.
How much does commercial door repair cost in North Hollywood?
It depends on the door, not on the neighborhood. The main factors are whether the fix is an adjustment, a part, or a full replacement, the grade and type of hardware, the condition of the door and frame, how many doors are involved, and when the work happens. We explain the options and what drives the cost before we start.
Do you handle office door lock repair and warehouse door lock repair?
Yes. Office doors tend to need work on levers, latches, cylinders, and keying, while warehouse doors tend to need stronger latches and protection from impact damage. We cover personnel doors and their hardware, but not overhead or dock doors.
Does summer heat in North Hollywood really affect my door?
It can. Hot, dry summers in the valley cause doors and frames to expand, and that is the main seasonal factor for exterior doors here. A door that closed cleanly in spring may rub or miss its strike in midsummer. We check alignment and the strike plate before suggesting any replacement.
Do I need to be on site, and can a tenant call for the work?
Someone with authority over the door should be reachable. If you are a tenant, the lease or the landlord may control hardware changes, so it helps to check before we begin. We will ask who is authorized to approve the work, especially on exterior or shared-entry doors.
Can you keep my existing keys working after a repair?
Often yes, when the fix is a latch, strike, or lever and the cylinder stays. If the cylinder has to be replaced, we can usually pin the new one to match your current key, depending on the lock. If you want to retire old keys, a rekey is the better tool. We confirm what is possible once we see the lock.
What should I ask before hiring a commercial locksmith?
Ask for their BSIS LCO license number, since California requires locksmith companies to hold one. Ask who will actually come to the door, and whether they will explain the repair and replace options before starting. A company that can't answer plainly is worth avoiding.
Do you take commercial door hardware calls at night or on weekends?
Yes. Our phone is answered 24 hours a day, seven days a week, year-round, at (213) 577-1366. A door that won't lock after hours is exactly the kind of call we expect.
