How we work
We are a mobile locksmith. We come to you.
The call
A locked office door, a tired mortise cylinder, or a master key that no longer turns cleanly is how the call usually reaches us for Terre Hill commercial lock work. The caller has already tried the key again, checked the door position, and looked at the lock from the outside. In Terre Hill, we hear about exit hardware that will not release, cylinders that bind, and keys that no longer match the lock’s feel. We come to you and work on the hardware there.
What we check first
Before we touch anything, we look at the lock body, the cylinder, the keyway, and the way the exit hardware sits on the door. We check whether the trouble is in the cylinder itself, the key, or the latch and trim around it. That first read tells us whether the work starts at the key side, the cylinder side, or the hardware side. On a Terre Hill commercial door, that decision sets the whole job and keeps us focused on the part that needs attention.
The work itself
At the door, we open the lock, remove the cylinder or trim as needed, and test the key and operating parts in place. On rim and mortise hardware, we work from the lock body and the mounting points; on bored cylindrical hardware, we work from the cylinder and trim. If the issue is with a master key setup, we sort the pins and keying in the cylinder. If the exit device is sticking, we open the hardware and inspect the parts inside the case.
What changes afterwards
When the work is finished, the new part is the cylinder or the keyed component inside it, and the adjusted part is the master key setup or the exit hardware latch and trim. That changes how the key enters, how the plug turns, and how the lock body moves under use. In Terre Hill, commercial lock work often leaves the outer hardware in place while the keyed parts are reset inside the lock. The cylinder, the key, and the exit hardware now meet at the same point in the lock body.

Commercial Locksmith, in short
Locks, cylinders, master keys and exit hardware on business premises.
Worth knowing
Rain and wet snow change the small details of the work. We wipe down the cylinder face, the latch, and the escutcheon so water does not run into the housing while we test the key and the bolt. If a rim or mortise lock has collected grit, we clean the exterior parts and clear the keyway area before we open the lock. The weather does not change the job itself. We still inspect the cylinder, check the key, and work on the lock body, the trim, and the exit hardware at the business door in Terre Hill.
Cold brings its own problems, but the parts are the same. A stiff mortise lock may have dried lubricant that turns gummy, and a bored cylindrical lock can bind at the latch if moisture has frozen at the edge of the housing. We do not force the knob or lever. We look at the set screws, the cylinder tailpiece, the latch case, and the strike alignment, then clean and reset the parts that need it. What does not change is the basic work: open the lock, inspect the cylinder, and service the hardware on the door.
Wind and blowing dust do not change what we check, only how carefully we protect the parts while we do it. We keep debris out of the keyway, test the master keying where it applies, and examine the exit device for drag at the latch bolt and the trim. On a wet frame or door face, we dry the contact points before we turn the key or test the release. The weather may make the lock feel different, but we still work on the same cylinders, keys, and exit hardware on the door.
Jobs we have done
Questions
My storefront mortise lock sticks after lunch; should we repair the cylinder or replace it?
We look at the wear in the cylinder, the condition of the key, and how the lock lines up in the door. If the core is the problem, we can rekey or replace that part. If the lock body is worn, we may need to replace the lock and fit it to the door.
I need one master key for our rear office and front entry; how do you set that up?
We set it up by sorting the locks into groups and matching the cylinders to one control key. That lets one key open the doors you want while other keys stay on their own locks. We also check the existing hardware so the new keying works with the locks already in place.
Our exit hardware on the warehouse door drags when I push it; what do you check first?
We check the latch, the alignment of the trim, and the condition of the exit hardware at the door. A dragging bar or loose trim can keep the hardware from moving cleanly. If parts are worn, we repair or replace the needed pieces and test the lock and release action at the door.
When my back office door key starts turning hard, should we replace the key or look at the cylinder?
We look at the cylinder first, because a worn key can point to wear inside the lock, not just a bad key. If we only copy the key, the same binding can keep showing up. We check the lock, match the fix to the part causing the trouble, and set the keying so the door opens from the right key.
After our storefront panic bar kept catching, is the latch the problem or the exit hardware behind it?
The latch may be the symptom, but the exit hardware can be the cause. We check how the bar, latch, and related parts line up and move together, then repair the part creating the drag instead of only easing the sticking point. That keeps us from chasing the same catch again on the next use.
