Commercial Locksmith - Master-Key Systems, Quoted in Writing

Trusted Commercial Locksmith Nationwide

A commercial locksmith handles the security hardware that keeps a business running: high-security cylinders, master key systems, panic bars, door closers, and storefront locks. Dunmore Locksmith has provided these services across the United States since 2007 through the Threshold Group network. Our technicians are background-checked, identity-verified, and sent to you by name and photo before they arrive. When a lock fails at 9:40 on a Tuesday morning, or a panic bar jams during a fire inspection, you need someone who answers the phone and shows up ready. That’s what we do. Call (910) 714-4287 and you’ll reach a live person, any hour, every day of the year.

The name Dunmore comes from old words for a great fort: a stronghold built to keep what’s inside safe. That’s the standard we work to on every commercial job. Written pricing before any work begins. A 365-day written guarantee on every repair. No surprises at the door, no vague promises. Just a technician you know by name, doing work that’s documented and guaranteed.

High Security Locks

High security locks are cylinders and deadbolts engineered to resist picking, drilling, bumping, and unauthorized key duplication. Businesses choose them when they protect cash, sensitive records, pharmaceuticals, or inventory that a standard lock simply can’t secure. Dunmore Locksmith installs and services high-security hardware from Medeco, Mul-T-Lock, and Abloy, with key control systems that prevent anyone from copying a key without your written authorization. Basic high-security cylinder installation typically runs $150 to $400 per opening, depending on the cylinder grade and whether restricted keyways are required.

Restricted Keyways and Key Control

A restricted keyway means blanks are only issued to authorized dealers, and duplicates require a signature card. That’s the difference between a lock that keeps honest people out and a lock that keeps dishonest people from getting a key in the first place. We walk you through the key control hierarchy before quoting anything.

When Standard Locks Are Not Enough

If you have had a break-in attempt, lost master keys, or high-turnover staff with access to sensitive areas, standard pin-tumbler hardware is a liability. High security locks give you a documented chain of custody. We recommend them for server rooms, pharmacies, cash offices, and anywhere proprietary information sits behind a door.

Commercial Door Repair

Commercial door repair covers the door itself: sagging hinges, misaligned frames, warped stiles, worn pivots, and strike plates that no longer line up. Doors in high-traffic buildings take thousands of cycles a week, and when one stops latching, the lock is only half the problem. Dunmore Locksmith repairs commercial doors and their hardware as a single system, because a new lock on a sagging door fails the same way the old one did; our Commercial Locksmith Maintenance Schedule: What to Do and When can help you avoid these issues. Most commercial door repairs run $120 to $450 depending on the hinge hardware, frame condition, and whether the door must be removed to be rehung.

Hinge and Pivot Repair

Continuous hinges and floor pivots wear differently than residential butt hinges. When a heavy storefront door drags on the threshold, the pivot bearings or hinge pins are usually gone. We replace them with commercial-grade hardware rated for the door’s full weight.

Frame and Strike Alignment

A door that won’t latch often has a strike plate that has drifted out of alignment from years of slamming. We re-seat or replace the strike, reinforce the frame with longer screws into the stud, and test the latch under real closing force. If the frame itself is split or rotted, we quote for a frame repair or replacement before any lock work goes in.

Master Key System

A master key system is a hierarchy of keys and cylinders that lets different people open different doors from a single key. A manager’s key might open every door in the building, while an employee’s key opens only the stockroom and the bathroom. Dunmore Locksmith designs, installs, and maintains master key systems using Schlage, Medeco, and Yale cylinders, with full key schedules and expansion charts so the system can grow. A basic master key setup for a small office with five to ten doors typically runs $300 to $800, including the cylinders and initial keys.

Designing the Hierarchy

We map every door and every employee role before cutting a single key. The goal is a system where no one carries more access than they need, and a lost key doesn’t mean rekeying the entire building. That planning is what separates a working master key system from a pile of keys that happen to overlap.

Lost Key Response

When a master key goes missing, the entire hierarchy may be compromised. We help you assess whether to rekey affected cylinders, cut new keys on a changed progression, or move to a restricted keyway. The written estimate covers every cylinder that would be touched, so there’s no scope creep after the fact.

Mortise Lock Replacement

Mortise lock replacement means removing an old mortise lock body from its pocket in the door and installing a new one that fits the same footprint or requires controlled modification. Mortise locks are the heavy rectangular lock bodies found in older commercial buildings, schools, and apartment entryways. They wear differently than cylindrical locks, and when the internal springs or deadlatch fail, the door often won’t open from one side or won’t stay latched. Dunmore Locksmith replaces mortise lock bodies with new hardware from Yale, Baldwin, and Sargent, typically $180 to $550 per opening depending on the trim, finish, and whether the door prep needs adjustment.

Matching the Existing Footprint

A mortise lock body must fit the pocket already cut into the door. We measure the faceplate, backset, and trim mounting points before ordering replacement hardware. If the old lock is discontinued, we identify a current model that fits with minimal door modification and quote the prep work separately.

When Repair Is Not Worth It

Some mortise lock bodies can be rebuilt, but when the case is cracked, the deadlatch is stripped, or replacement parts are no longer manufactured, replacement is cheaper in the long run. We’ll show you the worn part and explain why a new body will outlast another repair. You make the call with the price in writing first.

Replace Commercial Door Lock

To replace a commercial door lock means swapping the entire locking hardware: cylinder, latch or deadbolt, trim, and sometimes the strike. It’s different from rekeying, which reuses the existing hardware and only changes the internal pins. Businesses replace locks after employee turnover, a lost key, a break-in, or simply because the old lock has worn past reliable service. Dunmore Locksmith replaces commercial locks with hardware rated for the door’s usage level, from Grade 3 light commercial to Grade 1 heavy-duty. A standard commercial lock replacement runs $150 to $400 per opening, including hardware and labor.

Grade Matters More Than Brand

A commercial lock gets an ANSI/BHMA grade: Grade 1 is rated for the hardest use, Grade 2 for moderate commercial, Grade 3 for light residential. We match the grade to the door’s actual traffic and security needs, not to what’s cheapest on the shelf. You’ll know exactly what grade you’re paying for and why.

Rekeying vs. Replacement

If the existing hardware is still in good shape and you just need to change who has access, a rekey costs less than a full replacement and takes about 20 minutes per lock. If the lock is loose, the finish is worn, or the latch doesn’t retract cleanly, replacement is the honest answer. We’ll tell you which one your door actually needs.

Panic Bar Installation

Panic bar installation puts an exit device on a commercial door so it opens with one push from the inside, no twisting, no turning, no key. These are the push bars required on doors in most commercial buildings, schools, and any assembly space. They save lives when people are moving fast toward an exit, and they fail inspections when installed wrong. Dunmore Locksmith installs rim, mortise, and vertical rod panic bars from Sargent, Yale, and other commercial brands. Full panic bar installation typically runs $350 to $900 per door, depending on the device type, door width, and whether the door needs additional prep.

Code Compliance and Fire Ratings

Panic hardware must meet local fire and building codes, and that usually means the door can’t be locked against exit from the inside. We install exit devices that meet the standard for the occupancy type, and we verify the door swings in the correct direction before any hardware goes on. A panic bar on a non-compliant door is an expensive way to fail an inspection.

Maintenance and Recertification

Panic bars take abuse, and the internal springs and dogging mechanisms wear out. We service existing exit devices, replace worn components, and test the hardware the same way an inspector would, following the steps in our Commercial Locksmith Troubleshooting: Common Problems and How to Fix Them. If your panic bar has been flagged, we will get it working before the reinspection date.

Storefront Door Repair

Storefront door repair covers the aluminum and glass entry systems on retail shops, restaurants, and offices. These doors are built differently than wood or steel doors: they hang on pivots or continuous hinges, ride on sweeps and thresholds, and swing against closers that are constantly being adjusted. When a storefront door sags, scrapes, or won’t latch, customers notice it immediately. Dunmore Locksmith repairs storefront doors on the door, the frame, and the hardware together, typically $150 to $500 depending on whether the problem is hinge wear, threshold damage, or closer failure.

Aluminum Frame and Glass Adjustment

Storefront doors often fall out of square because the pivot hardware wears or the frame was never properly shimmed. We adjust the pivots, re-shim the frame, and reset the door so the latch actually catches. If the glass is cracked or the frame is bent, we will tell you before quoting any lock work.

Latch and Strike Repair on Storefronts

The latch on a storefront door often fails because the closer slams the door hard enough to deform the strike. We replace the strike, adjust the closer speed, and test the door through fifty real open-close cycles. That’s the difference between a repair that lasts a week and one that lasts years.

Commercial Door Closer Repair

Commercial door closer repair fixes the hydraulic or pneumatic device at the top of the door that controls how it closes. A closer that slams, drifts, or won’t close at all is both a safety problem and a security problem: a door that doesn’t close behind you is a door that isn’t locked. Dunmore Locksmith repairs and replaces commercial door closers from major manufacturers, typically $120 to $350 per door depending on whether the closer can be rebuilt or needs replacement and whether it’s surface-mounted or concealed in the frame.

Adjustment vs. Replacement

Many closers can be brought back to spec with adjustment of the sweep, latch, and backcheck valves. When the seals are blown or oil is leaking down the door, replacement is the only real fix. We test the closing force with a pull gauge and show you the reading before and after.

Concealed Closers in Aluminum Doors

Concealed closers live inside the door or frame and are harder to service than surface-mounted units. We remove the door from its pivots, service or replace the closer, and rehang the door with the tension set correctly. You’ll get a written price for the full job, not a per-hour guess.

Brands We Service

We’re factory-authorized to install and service Medeco high-security cylinders, which means we have access to the proprietary keyways, pinned cylinders, and technical support that a general locksmith doesn’t. When you need true key control on a Medeco system, we can cut and issue keys under the original factory card, and we keep the records that keep your system intact.

We work extensively with Yale and Baldwin commercial hardware, from mortise lock bodies to exit devices and door closers. Whether you have Yale hardware in an office building or Baldwin mortise locks in a boutique storefront, we stock common OEM parts and know the quirks of each product line. And if you have Mul-T-Lock high-security cylinders or any other major brand, we service those too. Whether you have one of these names on your doors or a brand nobody recognizes anymore, we can help.

Signs You Need a Pro Right Now

• Your key turns but the door won’t open. The cylinder tailpiece or the lock’s internal mechanism has likely broken. Forcing the key further can snap it off inside the lock, which turns a repair into a lockout plus extraction.
• The door won’t latch when it closes. A door that bounces open isn’t just drafts; it means the latch isn’t reaching the strike. That leaves the building unsecured overnight and the door itself takes more abuse with every cycle.
• A panic bar feels stiff or makes a grinding sound. Exit devices have internal springs and dogging mechanisms that wear out. A panic bar that fails during an emergency exit or a fire inspection is a code violation and a legal liability.
• You’ve lost track of who has keys. If former employees might still have working keys, your locks are compromised even if nothing has happened yet. Rekeying or replacing affected cylinders closes that gap the same day.
• The door closer slams the door hard enough to shake the frame. A closer adjusted too fast or failing internally stresses the hinge, the latch, and the frame every single cycle. It’s a small repair today or a bigger one in six months.

Our Process, Step by Step

1. 1
   You call and describe the problem. A live person answers, any hour. We ask about the door type, the hardware brand, and what it’s doing or not doing. We give you a realistic expectation for response time and price range over the phone.
2. 2
   Your technician arrives, and you already know who to expect. Before the visit, we send the technician’s name and photo. At the door, they show a photo ID badge. If anyone arrives who you weren’t told to expect, that visit is covered at no charge.
3. 3
   The technician diagnoses the problem in front of you. We inspect the door, the frame, the hardware, and the strike as one system. We’ll show you exactly what’s failed and explain what has to happen to fix it.
4. 4
   You get a written price before any work starts. The price you approve is the price on the invoice. No added trip charges, no surprise fees at the end, no bait pricing. If the job changes because we find something hidden, we stop and get your approval before continuing.
5. 5
   The work is done and guaranteed in writing. Every repair carries our 365-Day Done Right Promise. If the repair fails within a year, we return and make it right at no charge. The guarantee is printed on your paperwork, not described over the phone.
