Why won't my commercial door latch or lock?
A commercial door that won't latch or lock is rarely a mystery once someone looks at it closely. Either the latch bolt isn't reaching the strike, the lock body inside the door has worn or broken, the cylinder turns but doesn't move the mechanism, or the door itself has shifted so the hardware no longer lines up. What you notice (a door that swings open, a key that spins, a handle that feels loose) points toward different causes, and describing it accurately on the phone helps us bring the right parts.
Doors in shops, offices, and warehouses take far more punishment than a house door. They cycle hundreds of times a day, get propped open for deliveries, get hit by carts, and often have a closer that is set too hard or too soft. Commercial hardware is built for this, but it still wears, and once a door sags even a fraction of an inch the latch stops catching reliably.
- The strike plate is out of line because the door has dropped on worn hinges or the frame has moved
- The door closer is too weak to pull the latch home, or so strong it slams and loosens everything over time
- The latch bolt is worn, sticky, or held back by a broken spring inside a mortise lock case
- The cylinder or its cam is worn, so the key turns without throwing the bolt
- The lever, spindle, or trim is loose or broken, so the handle turns but nothing retracts
- The door or frame was damaged in a forced-entry attempt and the hardware is bent
- Debris, paint, or thermal movement on a metal door has changed how the latch seats
Which commercial door hardware do we repair?
The core of this work is the lock and latch hardware on commercial doors. A mortise lock is a rectangular steel case set into a pocket cut into the edge of the door. It holds the latch bolt, often a deadbolt, the springs, and the lever mechanism, with a cylinder screwed into the front. These are common on older storefronts and office buildings, they are heavy and durable, and because their parts are serviceable, repair is often realistic where a cheaper lock would simply be swapped out.
We also work on cylindrical locks (the kind where the lever passes through a round hole bored in the door), rim-mounted locks and deadlocks, exit hardware, strikes and frames, hinges that are letting a door sag, and the hardware behind keyed-alike and master-keyed setups. If your issue is purely a gate, a closer, or a push-bar, those have their own pages and we link to them below.
- Mortise lock cases, cylinders, levers, and trim
- Cylindrical and heavy-duty lever locks on office and storeroom doors
- Latch bolts, deadlatches, and strike plates that no longer engage
- Hinges, pivots, and door alignment problems that cause latching failures
- Rim cylinders and deadlocks on steel back doors
- Broken or loose handles, spindles, and escutcheons

Call (213) 577-1366How do we handle a commercial door hardware call?
We try to fix the right thing the first time, which means looking at the whole door and not just the lock. Here is how a typical call goes.
- You call (213) 577-1366 and tell us what the door does, what it is made of (wood, hollow metal, aluminum storefront, glass), and whether you can secure the building another way for now.
- We talk through anything you can safely do before we arrive, such as using another door or keeping someone on site, so the building isn't left open longer than necessary.
- We come out in a mobile van stocked with common commercial lock parts and start with the door, not the lock: hinges, closer, frame, strike, and latch bolt alignment.
- We tell you plainly what failed and what the options are, usually an adjustment, a repair of the existing hardware, or a replacement of that piece, and we explain the cost before we start work.
- We do the work: realign or replace the strike, rebuild or replace a mortise case, change a worn cylinder, tighten or replace trim, or correct the hinge problem causing the latch to miss.
- We test it the way the door is actually used: closed on its own closer, latched, locked and unlocked with every key you hand us, and opened from the inside to confirm free exit.
- If keys are an issue, we can rekey the cylinder so lost or ex-employee keys stop working, and we leave you with working keys and a note on what to watch for.
Should the hardware be repaired or replaced?
Honestly, it depends on what has failed and how much life the rest of the lock has. A strike that is a few degrees off, a loose set screw, or a worn cylinder is usually a repair, and that is typically the more economical route. A mortise case with a snapped internal spring can often be rebuilt if parts exist, but if the case is badly worn or the parts are no longer made, replacing it with a current equivalent is the sounder decision.
We would rather tell you when a repair is a short-term patch. If a door keeps failing because the frame is bent or the hinges are tired, replacing a lock won't hold, and we'll say so. We also try to match the existing finish and function where we can, so the door still looks like the rest of the building and the lock still behaves the way your staff expects.

Call (213) 577-1366What affects the cost of commercial door hardware repair?
We don't quote numbers on a web page because two doors that look identical can need very different work. What we can do is tell you what moves the cost up or down, so the figure you hear on a call makes sense.
- What actually failed: an alignment adjustment is a different job from rebuilding a mortise case or replacing a whole lockset
- The type and grade of hardware: heavy-duty commercial locks and specialty cases cost more than light-duty ones
- Whether the part is on our van or has to be sourced, which is common with older mortise locks
- The condition of the door and frame, since a bent frame or sagging door adds work beyond the lock
- How many doors are involved and whether they share a keying system
- Whether the door is on an exit path and has specific hardware requirements
- When you call: after-hours and emergency visits are priced differently from scheduled work
- Rekeying, keyed-alike, or master-key needs layered on top of the repair
What about office and warehouse door locks?
Office door lock repair is often about function as much as failure. Office doors usually use a lock that can be locked from outside with a key and unlocked from inside without one; storeroom doors stay locked from outside at all times. If a replacement lock has the wrong function, staff will either lock themselves out or leave the door unsecured, so we match function carefully. When employees leave or keys go missing, rekeying is usually the lighter-cost fix compared with replacing hardware, and if you're managing many keys, a master key system can keep control manageable.
Warehouse door lock repair is a different environment. Steel personnel doors, rim cylinders, deadlocks, and heavy exit hardware get hit by pallet jacks, slammed by wind, and left propped open. Failures there are often bent latches, loose mounting, or a door that no longer closes square. If the real culprit is a worn closer, our door closer repair page explains how we approach that, and for exit bars see panic bar installation.
One thing we won't compromise: a door on an exit path has to open from the inside without a key or special knowledge. We don't make fixes that undermine that, and your fire marshal or building department has the final say on requirements for your building.
What does commercial door hardware work look like in Granada Hills?
Granada Hills (ZIP 91344) is mostly single-story ranch tracts, with multifamily housing limited and concentrated near the main boulevards. That's worth knowing because it means much of the commercial door hardware in the area sits along those corridors: Devonshire Street, Zelzah Avenue, and San Fernando Mission Boulevard, and in the Old Granada Village business district on Chatsworth Street. Storefront lock service in Old Granada Village is one of the jobs we expect here, and our storefront lock repair page covers glass and aluminum doors in more detail.
The north Valley foothill setting brings hot summers and gusty Santa Ana winds off the hills in the fall. Sun-exposed south-facing doors and wind-stressed gates see the most seasonal wear. For commercial hardware, that can mean a metal door that expands slightly in the heat and starts to bind at the latch, or a closer that struggles against a gust and leaves the door resting just short of latched. If a door only misbehaves on certain afternoons or windy days, that's useful information to give us on the phone. For perimeter gates, see gate lock repair.
If your business is in North Granada Hills above the 118, or out toward the O'Melveny Park and Bee Canyon foothills, we serve those addresses too. Our storefront is at 10740 Wilshire Blvd in Westwood, roughly 23 miles away, and our mobile vans cover the distance so the work happens at your door.

What should I ask any locksmith before they work on my door?
California requires locksmith companies to hold a Locksmith Company (LCO) license through the Bureau of Security and Investigative Services (BSIS). Ask any locksmith you're considering for their license number, and check it yourself. Also ask whether the person who answers the phone is the company that will arrive, what the price depends on, and whether they'll explain the work before they begin.
A good locksmith will tell you what failed, show you the worn part if you ask, and be upfront about whether a repair is a lasting fix. That is the standard we hold ourselves to.
Frequently asked questions
Why does my commercial door only latch if I slam it?
Usually the latch bolt and strike plate are slightly out of line, the closer isn't pulling the door fully into the frame, or the hinges have worn and let the door sag. Slamming forces the latch past the misalignment, but it also damages the hardware over time. Having it adjusted is typically much less work than replacing what slamming eventually breaks.
Can a mortise lock be repaired, or does it have to be replaced?
Often it can be repaired. Mortise cases are serviceable, so a worn cylinder, broken spring, or loose trim can be fixed without replacing the whole lock. If the case is badly worn or parts are no longer available, we'll tell you and recommend a replacement that fits the existing door preparation where possible.
How much does commercial door hardware repair cost in Granada Hills?
It depends on what failed, the grade of hardware, whether parts are on hand, the condition of the door and frame, how many doors are involved, and whether you call after hours. We explain the work and the cost before we begin. A simple strike adjustment and a mortise case rebuild are very different jobs, so we won't guess on a web page.
My commercial door won't lock at night. Can you make it secure?
Yes, that's a common call, and we answer 24 hours a day at (213) 577-1366. Tell us what the door does and we'll talk through what to do in the meantime. When we arrive we repair or replace the failing piece so the door actually locks, and we test it before we leave.
Do you repair warehouse door locks and steel doors?
Yes. Steel personnel doors, rim cylinders, deadlocks, and heavy-duty exit hardware are part of our work, along with the hinges and frames that cause latching trouble. If the door is a roll-up or a gate, we may route you to our gate lock page or look at it in person first.
Will repairing my door hardware affect fire or exit requirements?
We don't make changes that stop a door from opening freely from the inside on an exit path. Your fire marshal or building department sets the specific requirements for your building, so if you're unsure what applies, check with them. We can describe what the hardware does and keep the repair consistent with it.
Do you serve Old Granada Village and the main boulevards?
Yes. We serve ZIP 91344 and the surrounding areas, including the Chatsworth Street business district in Old Granada Village and the Devonshire Street, Zelzah Avenue, and San Fernando Mission Boulevard corridors. Our mobile vans come to you from our Westwood storefront.
Do I need to be the property owner to authorize the work?
No, but we do need to confirm you have the authority to change or repair the lock. A tenant, business owner, or property manager can usually authorize it. If the landlord controls the building hardware, it's worth checking your lease before we start.
Can you keep my existing keys working after the repair?
Often, yes. If we're repairing a lock and the cylinder is sound, your keys stay the same. If we replace a cylinder, we can pin it to match your existing key or rekey it to a new one, which is also the better choice if keys have gone missing.
