A business lock is a different animal from the one on your front door. It cycles hundreds of times a day, carries life-safety duties, and often sits inside a master-key plan that has to stay coherent as staff come and go. Here is what commercial work in Denver actually covers.
Commercial work splits into a handful of recurring jobs, and most Denver businesses need a few of them over time. The core list is lockouts, rekeys, master-key builds, panic and exit hardware, door closers, and high-security upgrades. A storefront on Colfax wants a fast lock change when a lease rolls. A clinic near the Anschutz campus in Aurora wants a master system that keeps exam rooms, supply rooms, and the front desk on separate access levels.
The thread connecting all of it is access control on a building people share. A home has one or two key holders. An office has a dozen, plus a cleaning crew, plus whoever the last manager handed a key to and never logged. Commercial locksmith service is as much about tracking who can open what as it is about the metal in the door.
A master-key system lets one key open many doors while individual keys open only their own, and a well-built one in Denver runs on a planned hierarchy rather than guesswork. The owner or facilities manager holds the master. A department lead might hold a sub-master for one wing. Each employee holds a change key that opens a single door. Done right, the chart on paper matches the pins in every cylinder.
The mistake we see most is a system that grew by accident. Someone added a door here, rekeyed one there, and now nobody knows which key opens what or how many copies of the master float around the building. When it reaches that point, a clean rebuild beats endless patching. We cover that in detail in our master-key rebuild guide, including the warning signs that a system has drifted past saving.
Panic bars and exit devices are life-safety hardware, so they have to let people out instantly even when the door is locked from outside. Denver businesses with assembly or high-occupancy spaces are required to keep egress free, which means a jammed or sticking exit device is not a someday fix. It is a same-day call. We service Von Duprin-style rim and mortise devices, vertical-rod hardware, and the door closers that pair with them.
Fire-rated doors add another layer. A rated door has to self-close and latch to do its job during a fire, so the closer, the latch, and the hardware all have to stay within spec. ADA adds yet another: lever handles and operating force matter for accessibility. When we replace commercial hardware, we keep these rules in view rather than just bolting on whatever fits the hole. Getting it wrong can fail an inspection or, worse, fail during an emergency.
Most commercial jobs run $150 to $400, and the figure tracks the complexity of the door, not a flat menu. A single lock change is near the low end. A master-key build across a dozen openings, a panic-bar replacement, or a switch to restricted high-security keyways climbs from there. After-hours response adds to the rate, and we say that out loud before we roll a truck.
| Service | Usual range | What drives the number |
|---|---|---|
| Commercial lockout | $150 to $400 | Lock type, time of day, door condition. |
| Storefront / office rekey | $150 to $400 | Cylinder count and keyway. |
| Panic bar / exit device service | $150 to $400+ | Repair vs full device replacement. |
| Master-key system build | Quoted by door count | Hierarchy size and keyway choice. |
| High-security cylinder upgrade | Higher per cylinder | Restricted, patent-controlled keyways. |
| After-hours commercial response | Add to standard rate | Overnight, weekend, or holiday dispatch. |
One thing worth knowing in Colorado: there is no statewide locksmith license. Anyone can print a card that says locksmith. For a business signing a recurring access-control relationship, that makes verifiable insurance, a real local address, and a written scope matter more, not less. Ask for a certificate of insurance before anyone touches your master system.
Call when access stops matching reality, not just when a lock breaks. The clearest triggers are staff turnover, a lost master key, a break-in, a failed inspection on exit hardware, or an expansion that adds doors to a system that was never designed to grow. Any one of those is a reason to bring someone out before the gap becomes a loss.
Centennial and the south Tech Center corridor see a lot of planned office and suite work, which is the calm version of this call. The harder version is reactive: a back exit that will not latch at close, or a former employee whose key was never recovered. After a break-in, the job widens to frame and strike-plate repair too, which we walk through in the break-in repair guide. Either way, the right move is a written quote and a plan before the work, covered on the Centennial service page as well.
Most commercial jobs run $150 to $400, and the spread depends on the work. A single storefront lock change sits near the low end, while a master-key rebuild, panic-bar repair, or a switch to high-security keyways climbs higher. We quote the full number in writing before any work starts, parts included.
Yes. We adjust, repair, and replace panic bars, exit devices, and door closers on Denver storefronts, offices, and clinics. Exit hardware is life-safety equipment, so it has to release freely on the way out while still locking from outside. We test the full release cycle before we leave the site.
We design and cut master-key systems so a manager key opens every door while staff keys open only their own. We map the hierarchy with you first, because a sloppy chart is the thing that bites you a year later when someone leaves. The build cost depends on door count and keyway choice.
A high-security cylinder resists picking and stops anyone copying your key at a hardware kiosk, because the blanks are patent-controlled and restricted. Denver businesses with cash, inventory, or regulated records lean toward them. They cost more per cylinder, but they close the loophole where an old staff key gets duplicated and never returned.
Yes. We run 24/7 for Denver-area businesses, so a jammed exit device or a lockout that strands an opening crew gets handled the same night. After-hours response adds to the standard rate, and we tell you that figure on the phone. A storefront that cannot lock at close is an emergency, and we treat it like one.
Master keys, panic hardware, high-security cylinders, and after-hours response across the metro. We quote the full figure in writing, parts included, before any work starts. Insured and local.
