- The call
- A new tenant moved into the unit next door, and the property manager just found three different cylinders on three doors, none of them cut to the same key.

Overnight someone forced the back door, and the cylinder face is scarred, the metal around the strike has pulled loose from the frame, and the latch no longer sits flush.
A business door rarely fails the same way a house door does, because it opens far more often and often has to satisfy a fire or egress rule a home door never faces. Replacement starts by identifying what the opening actually is: a mortise-prepped steel door, a narrow-stile aluminum storefront, a fire-rated door that needs listed hardware, or an exit serving enough people that code calls for panic-style release. The locksmith fits hardware built for that specific opening, connects it correctly to any electric strike or access-control wiring already present, and hands over keys cut and logged to the business's own system.

Scene 1
The last part of the assessment looks past today's problem to how the business expects to manage this door going forward: does staff turnover happen often enough that an interchangeable core, which lets a key holder change the combination without pulling the whole cylinder, would pay for itself in convenience? Does the business want a restricted keyway so blanks cannot be cut at an ordinary hardware counter? These questions shape the specific hardware ordered as much as the door's physical construction does.
Scene 2
The new hardware is installed into the existing prep, with the lock body or lockset, strike and any reinforcing plate seated so the door closes without binding. On a narrow-stile storefront door, the hookbolt or deadlatch is aligned so it engages the keeper across its full travel rather than catching on one edge. On a mortise-prepped door, the case is fitted so the trim sits flush and the spindle and cylinder line up with the existing holes cut for them.
Scene 3
The business keeps a plain account of what was fitted: the hardware model and function, the keying it was cut to, how many keys were issued and to whom, and any fire or exit rating the door carries. For a property manager or facilities team, this record answers the next question about that door without another site visit, and for a business with several locations it becomes a reference for bringing other branches onto the same standard over time.
What shapes the quoteNorval Locksmith Pros
FeesSame any hour
Yes. An electric strike has to suit the latch or deadlatch type it will receive, the door's handing and swing, and whether the application needs fail-safe or fail-secure operation, meaning whether the door should unlock or stay locked if power is lost. Choosing a strike without checking these against the mechanical lock is a common reason a door releases electronically but still binds mechanically.
Yes. Exit devices and panic hardware are mechanical assemblies that see heavy use on a required exit, so periodic checking that the latch engages fully, the release bar moves freely, and any electrified or alarmed function still triggers correctly is worth building into the same schedule as other fire-safety equipment in the building.
Yes. An aluminum storefront door has a narrow stile, the vertical metal frame around the glass, that a standard mortise or cylindrical lock cannot physically fit into. These doors take a narrow-stile lock or a hookbolt built specifically for that slim profile, and matching the hardware to the frame is what lets the bolt engage the keeper fully instead of catching at an angle.
