How we work
We are a mobile locksmith. We come to you.
The call
A call about a commercial lock in Denver usually comes after a key sticks, a cylinder will not turn cleanly, or a master key no longer matches the lock the way it did before. The caller has often already tried the key again, checked the other side of the door, and worked the lever or thumbturn several times. We listen for the lock type, the hardware on the door, and whether the problem is in the cylinder, the key, or the exit hardware before we plan the work.
What we check first
Before we touch anything, we look at the lock body, the cylinder, the keyway, and the exit hardware as they sit on the door. We check whether it is a rim, mortise, or bored cylindrical lock, and whether the issue points to one part or the whole set. That first look decides whether we open the lock, rekey the cylinder, adjust the master key setup, or correct the hardware that is binding in Denver or nearby Ephrata. The wrong approach can change the rest of the job.
The work itself
At the door, we work on the lock in place and open it, then inspect the cylinder, the key, and the exit hardware for wear or mismatch. If the master key system is part of the trouble, we adjust the cylinders so the keying matches the intended setup. If the lock body is the issue, we replace the affected part and fit it to the door hardware already there. In a commercial job, that can mean a straight lock swap, a cylinder change, or work on the exit device.
What changes afterwards
After the work, the changed part is usually the cylinder or the lock body, while the adjusted part may be the master keying inside the same hardware. A new cylinder changes how the key enters and turns, and a reset master key setup changes which keys belong to which lock. On Denver commercial hardware, that can leave one lock with a different core, another with adjusted keying, and the exit hardware seated to the door with the new lock parts in place.

Worth knowing
At a house, a lock job usually centers on one opening and one key. We may pull a bored cylindrical lock apart at the knob and cylinder, check the tailpiece, and swap the cylinder if the key no longer turns cleanly. At a business, the same work can involve several doors tied to one master key. We then match the cylinder to the rest of the set, check the inside and outside trim, and keep each door keyed for the right level of access, not just one user.
House locks are often simple deadbolts or knob locks with one latch and one key profile, so the work stays close to the cylinder and the bolt. On a business door, we may be dealing with a mortise lock body, a rim cylinder, or exit hardware that uses a separate dogging or latch release. A worn commercial key can affect more than one door in Denver, so we check each keyway, each cylinder, and each lever or paddle that ties into the exit device.
The difference also shows up in how a lock is set up after repair. At a house, one cylinder may be rekeyed to fit the front and back doors, and the spare keys stay limited to that home. At a business, master key work has to preserve the change keys for offices, storage rooms, and service doors while keeping the master side aligned across the whole set. We test the cylinder rotation, the latch travel, and the exit hardware so each door matches its own use.

Questions
My office door in Denver uses a master key; can we have that changed without replacing every lock?
Yes, we can rekey the cylinders and set the new keying so one key opens the locks you want under that system. We also check how each cylinder is pinned and how the master key layers into the setup, then test the keys against the doors and hardware.
The exit bar on our rear door is sticking after the latch catches; what do you check first?
We check the exit hardware for binding, worn parts, loose fasteners, and a latch that is not moving cleanly with the rest of the door hardware. We also look at the cylinder if the door has keyed access on the same opening, so we can sort out whether the trouble is in the bar or the lock.
I need the storage room key changed after an employee left with it; can you rekey just that bored cylindrical lock?
Yes, we can rekey that lock and set a new key for the storage room door without changing the whole door set. We also make sure the cylinder matches the door hardware and that the old key no longer fits the new keying pattern on that lock.
When you're working on my front office door lock, do I need to stand there and answer questions?
No. We only ask for the details that matter, like which door, which key, and what the lock is doing. After that, you can stay nearby or step away while we work. If something changes, we may ask one more question before we keep going on the lock.
While you’re changing the master key setup on my rear entry, what should I tell my staff?
Tell them which key is changing hands and which doors it should still open. That keeps the work clear while we rekey the cylinders and check the exit hardware. If there are doors that need to stay on a different key, we sort that out before we finish with the key.
