A cook stepped into the alley with the recycling and the rear door swung shut behind him. The push bar works from inside, but the outside handle has a keyed cylinder and the key is hanging in the kitchen office.
On a commercial door the lock is rarely alone. A door contact feeds the alarm panel, a card reader drives an electric strike or a magnetic lock, and a monitoring company is watching for an opening outside business hours. A business lockout therefore starts with a conversation about those systems: who can disarm the alarm, whether the monitoring station should be told to expect an entry, and whether the electrified hardware has a mechanical override. Handling that first means the door opens without a patrol being dispatched, the access system is left working as designed, and the reader can be reset once someone is inside.

Scene 1
A storefront cylinder lives a hard life: sidewalk salt, slush, rain and a thousand key turns a month. In winter the locksmith checks for frost on the cylinder face, tests how far the key seats, and judges whether cold grease or real ice is holding the plug. In any season the keyway is inspected for grit and a worn key is compared with a fresh one, since a copy of a copy stops lifting the pins cleanly long before it breaks. This tells the locksmith whether a patient thaw, a cleaning and dry lubricant, or a new cylinder is the right response, and what to leave behind so the same morning is not repeated.
Scene 2
When a key is lost or unreturned, the second half of the visit is rekeying. Mortise and rim cylinders are removed, the plug slid out with a follower, and the bottom pins changed to a new combination so a fresh key operates them and the old one turns nothing. Where the building uses interchangeable cores, the core is swapped for one on a new combination. Cylinders that shared the old key are brought onto the new one, and if the door sits within a master key system the change is planned with the property manager so building keys keep working. New keys are cut, tested in every door and recorded against named holders.
Scene 3
After a rekey or a core swap you receive a counted set of new keys, cut from the fresh combination rather than copied from a worn original. The sensible next step is a key register: a page or spreadsheet naming each keyholder, the key they carry and the date it was issued, updated when someone leaves. Manufacturers put it plainly: locks only limit access if the keys that work them are controlled. A restricted keyway, where blanks are supplied only through authorised channels, puts real controls around duplication, though the exact process varies by program, and can be introduced now or later. Interchangeable cores make future staff changes a matter of swapping a core rather than a rekey.
What shapes the quoteJarvis Lock & Key Specialists
FeesSame any hour
An interchangeable core is a small, self-contained cylinder that slides out of the lock with a special control key and drops back in on a new combination. Look at the keyway: a figure-eight shaped face on a lever or mortise housing is the usual sign. Buildings choose them because a lost key or a staff change is handled by swapping the core rather than taking the lock apart, and a locksmith can carry cores pinned to your system.
A restricted or patented keyway is one whose blanks are supplied only through the manufacturer's authorised channels, so duplication is controlled rather than available at an ordinary counter, though the exact authorisation step varies by program and is not always a signed letter. For a company with staff turnover, cleaners and contractors, it means the keys in circulation are far easier to track. It can be introduced during a rekey, on the exterior doors only or across the whole premises, and works alongside a key register.
It is treated as one, with the same authority check: your new lease and identification settle it. The locksmith opens the previous occupant's locks, then rekeys or replaces them so keys still floating around from the last tenant stop working. It is also the moment to decide how the unit will be keyed: one key for every door, separate keys for the cash office and stockroom, or cores that suit a growing staff.
