How we work
We are a mobile locksmith. We come to you.
The call
When a commercial lock problem reaches us in Trainer, it is usually after someone has already tried the key again, checked the wrong key ring, or fought with a cylinder that will not turn. The call is often about a storefront lock, a mortise lock, or exit hardware that is binding at the opening. We listen for what the hardware is doing and what was tried before, because that tells us whether the issue is the lock, the key, or the way the parts are set in Trainer.
What we check first
Before we touch anything, we look at the lock body, the cylinder face, the keyway, and the exit hardware around it. We also check whether the lock is part of a master key system and whether the key is meant to control only one cylinder or several. That matters because a change in one part can affect the rest of the setup. On a job in Trainer or nearby Yeadon, that first inspection decides whether we open the lock, reset the cylinder, or adjust the hardware first.
The work itself
At the door, we open the lock and work on the parts that control the key and the latch. That can mean removing the cylinder, resetting the keyed parts inside it, or fitting the cylinder back into a mortise, rim, or bored cylindrical lock body. If the job involves exit hardware, we check the trim, the latch movement, and the way the mechanism returns. We stay with the hardware itself and do the work on site, without turning the job into a larger door repair.
What changes afterwards
After the work, the change is in the hardware, not in the door. The cylinder carries a different key arrangement, the master key setup is altered where needed, and the exit hardware has been adjusted so its parts move with less drag. In Trainer, that may mean one cylinder no longer matches the old key pattern while another part of the system stays in place. The lock body stays the same, but the keyed portion and the moving hardware have been reset for the next use.

Locks, cylinders, master keys and exit hardware on business premises.
Worth knowing
A key can keep fitting for a long time while the inside of the cylinder changes little by little. The plug gets scored where the key face drags across it, the key bitting rounds off, and old grease turns sticky in the shell. Dust and metal wear settle in the keyway and around the tailpiece, so the key starts to meet drag before it ever reaches the turn. We check the cylinder body, plug, and cam, then open it and clean the working parts by hand.
On mortise locks, the wear can hide in the case long before the bolt feels wrong. The hub, spindle, and cam plate can pick up side wear, and the key may still enter while the plug binds under load. In Trainer, we see keys that have worn from years of small twists, with the cut edges polished smooth and the lock cylinder matching that wear. We remove the cylinder or lock body, inspect the moving parts, clear out hardened residue, and replace damaged pieces when the wear has gone past cleaning.
Exit hardware can show the same slow buildup. The latch retractor, trim spindle, and cylinder tailpiece can all drag a little more each month, and the change is easy to miss until the key stops turning and the lever feels wrong. We check the cylinder, latch case, and connected parts for wear marks, broken springs, and loose set screws. Then we open the hardware, clean out packed dirt, tighten what has worked loose, and replace worn cylinders, master key parts, or exit hardware pieces as needed at the door.
Jobs we have done
Questions
My rear office door key turns, but the deadbolt still feels stuck. What do you check first?
We check the cylinder, the bolt, and how the lock body sits in the door. A key that turns but does not move the bolt can point to internal wear, a loose cylinder, or a worn linkage. We open the lock, repair or replace the affected part, and set it so the key and bolt move together.
I need one master key for our front and supply-room locks in Trainer. How do you set that up?
We set up the cylinders so one master key works across the locks you want grouped together. That starts with matching the pinning inside each cylinder and making sure the keys you keep separate still stay separate. We can also replace worn cylinders at the same time, so the whole group is set up as one system.
The push bar on our side exit is loose, and the latch has started catching. What gets looked at?
We check the exit hardware, the latch, and the cylinder that controls the door. A loose push bar can let the latch sit crooked, which makes the door hard to use. We tighten or replace the worn parts, then test the lock and bar together on the door and latch.
I have a storefront door with a mortise lock and the cylinder is sticking out; does that change the work?
Yes. A mortise lock usually means we work with the lock body and cylinder as one setup, while a bored cylindrical lock uses a different layout on the door. We match the job to what is already there, so the parts we service fit the hardware instead of forcing the door to fit the lock.
My exit hardware on the office door keeps dragging; does that change whether you swap the cylinder or the whole device?
Yes. With exit hardware, the existing device decides a lot of the work. If the cylinder is the part that needs attention, we can focus there; if the body of the hardware is the problem, we work on that lock assembly instead. The door’s setup tells us which path makes sense.
