How we work
We are a mobile locksmith. We come to you.
What this covers
Commercial locksmith work covers the locks and hardware on a business door that has stopped behaving the way it should. That can mean a key that no longer turns cleanly, a cylinder that needs attention, a master key setup that needs to be adjusted, or exit hardware that is not latching or opening right. We come to you and work on the equipment where it is installed, so the job starts with the lock, the key, and the door as they are.
How we approach it
No two jobs look the same. One may be a simple lock change, another may need a cylinder replaced, and another may involve a master key system that needs to be sorted out so different doors respond the way they should. We look at the door, the lock style, and the way the hardware is built before we start. Some jobs are straightforward, and some need careful work because the parts are older, mixed, or already worn. The approach changes with the lock.
Where it stops
We do not handle access systems, card readers, cameras, alarms, or other building controls. We also do not make code or compliance claims. This page is about the physical lock work on business premises in south-eastern Pennsylvania, including the locks, cylinders, master keys, and exit hardware that need attention. When a key sticks, a cylinder fails, or exit hardware stops moving right, the work stays with the lock and the key at the door

Locks, cylinders, master keys and exit hardware on business premises.
Worth knowing
We check the parts behind the face of the lock that people rarely look at, starting with the cylinder retaining screw, the tailpiece, and the latch case. A key can feel fine while the screw has backed out, the tailpiece is not sitting in the slot, or the latch is dragging inside the case. We also look at the spindle and trim ring for looseness, and at the way the cylinder sits in the door so the plug does not twist under use. Those small shifts can change how the lock opens and closes.
On master key work, we check the cylinders that do not show trouble until the key is tried in the right door. We test the control key and the change keys at the cylinder, then look at the bitting cuts for uneven wear, bent keys, and rough spots at the plug face. We also inspect the top pins, springs, and follower area after the cylinder is pulled so we can see whether one worn chamber is holding the rest of the stack out of line. The keying details matter as much as the hardware.
With exit hardware, we check the pieces people assume are fine because the bar still moves. We look at the latchbolt head, the touch bar or paddle, the dogging parts, the keeper, and the screws that hold the device to the door. A loose fastener, a bent latch, or a worn retractor can leave the device feeling normal while it is not seating the way it should. We also check the cylinder in the trim, the cam, and the linkage inside the exit device, then open the unit and inspect the lock body itself.
Commercial Locksmith: questions before you call
My office front door key turns halfway and stops. What do I need to tell you before you come?
Tell us whether it is a mortise cylinder, a bored cylindrical lock, or a rim cylinder if you know, and whether the key stops on both sides or only one. One useful detail is the shape on the inside. A long metal case means mortise hardware, while a round knob or lever set points to a bored cylindrical lock.
I need the back warehouse door rekeyed after a staffing change. What should I have ready?
Have every key that still needs to work that door ready for us to check, and know whether any other doors should match it. If one key now opens both the warehouse door and the side office, say that at the start. That tells us whether the job is only that one cylinder or part of a larger key setup.
Our suite entry has a push bar inside and a keyed lever outside. How does that change the job?
It changes the job because the outside key cylinder and the inside exit hardware are separate parts that work together. Tell us exactly what the outside trim does now when unlocked and when locked. One concrete detail matters here. On some setups, the outside lever goes slack when locked instead of staying rigid.
I have two storefront doors, and I only want one employee key to open both. Is that a rekey or a master key job?
That is a same-key job if you want one key to open both doors and no different levels above or below it. A master key job is different. It adds at least one second level where, for example, a manager key opens both doors but an employee key opens only the stockroom door.
The rear metal door drags at the threshold, and the key is hard to turn. Is that a lock problem or a door problem?
It can be either, so tell us what the door does before you touch the key. One detail helps right away. If you need to pull the door toward you or lift it a little for the key to turn, the bolt and strike may be out of line even if the cylinder itself also needs work.
