How we work
We are a mobile locksmith. We come to you.
The call
A call from Eddystone usually starts with a lock that has been forced by wear, a key that no longer turns cleanly, or exit hardware that does not release the way it should. On the phone, we hear what has already been tried: the key turned partway, the cylinder was checked again, the latch was jiggled, or the door was moved against pressure. That tells us whether the issue sits in the cylinder, the master key setup, or the exit hardware before we come to the premises.
What we check first
Before we touch anything, we look at the lock body, the cylinder face, the keyway, and the way the hardware sits in the door. On a commercial setup in Eddystone, that first look matters because rim, mortise, and bored cylindrical locks all fail in different ways. A master key system adds another layer, so we check which key is in use and how the cylinder is responding. That decides whether we are opening the lock, resetting the cylinder, or changing the keying.
The work itself
At the door, we work on the hardware in place. We open the lock, then remove or reset the cylinder as the job calls for, and we adjust the master key setup when the lockset is built that way. If the exit hardware is dragging or not releasing cleanly, we inspect the latch and the internal parts that control it. In Eddystone, commercial locks and exit hardware are often tied together, so one part may need attention before the rest can be set right.
What changes afterwards
After the work, the change is in the lock body and the cylinder. A new cylinder changes the key cut relationship inside the lock, while an adjusted master key setup changes which key operates which cylinder. On exit hardware, the latch and release parts are reset so their movement is different than before. The lock turns on a different feel, the key meets less drag, and the hardware sits with its parts aligned the way the repair left them.

Worth knowing
On an older building in Eddystone, a keyed entry may show up as a loose mortise cylinder, a cam that no longer turns cleanly, or a rim cylinder with a worn tailpiece that does not sit straight in the lock body. On a newer building, the same trouble is more likely in a bored cylindrical lock where the key turns hard because the cylinder core is worn or the mounting screws have shifted. The work changes with the housing, so we remove the cylinder, check the turning parts, and replace the worn pieces that affect the lock.
With master key work, older buildings often have mixed hardware on the same suite doors, so one bad cylinder can throw off several keys and make the problem look like a lock issue in the wrong place. Newer buildings usually have a cleaner system, so a single changed cylinder or a mismatched key can be the real cause. That changes the repair. We compare the door cylinder to the master key setup, swap in the correct cylinder when needed, and reset the pins inside the lock body so the right keys match the right door.
Exit hardware shows the same pattern. On an older building, a sticking exit device may have a bent latch, a tired dogging part, or a rim cylinder that no longer lines up with the hardware on the door. On a newer building, the complaint may be a push bar that feels fine but a cylinder that is loose in the trim or an interior trim piece that has shifted. The fix depends on the mounting style, so we tighten the fasteners, reset the cylinder, and open the exit hardware for inspection.
Jobs we have done
Questions
Can you rekey the back office cylinder after an employee key was not returned?
Yes, we can rekey that cylinder so the old key no longer works it. We can also check whether the cylinder is worn or sticking while we have it open, and set up the new keying so your staff uses one key for the door without changing the hardware on the door.
If the master key for our storefront doors is starting to stick, what do you check first?
We check the key, the cylinder, and the way the lock is set up before we change anything. A sticking master key can point to wear inside the cylinder or a mismatch in the keying, and we can correct that while keeping the existing lock body in place.
How do you handle a rear exit device that feels loose on our warehouse door?
We check the exit hardware for looseness, wear, and misalignment at the locking points, then tighten or replace the parts that control the latch action. If the device has been forced or is binding, we can rebuild the keying and cylinder side of it so the door closes and locks cleanly.
My side office door key got stuck in freezing rain, what changes for you in bad weather?
The weather mainly changes the approach to the outside hardware and the amount of cleanup around it. We may need to dry the keyway, clear slush, and work more carefully around wet metal and gloves. What does not change is the lock itself: we still open the lock, assess the cylinder, and handle the hardware on your business door.
When snow hits, does my rear warehouse exit hardware need a different kind of service?
The service stays the same, but wet snow can hide wear, ice can bind the latch, and cold metal can be harder to handle. We still check the exit hardware, the cylinder, and the keying on the door the same way. What does not change is the work itself: we open the lock and service the hardware on site.
