A locksmith's week in Middlesex Centre is a mix of small fixes and bigger decisions. A cylinder rekeyed after a lost key, a deadbolt added to a door that never had one, a shop rekeyed after staff changes, a safe that finally opens.

Every square is one home in a hundred.
Entry comes first and repairs second. Once authority is confirmed the door is opened, staff go in and start their routine, and the locksmith turns to the cause: extracting a broken key, rekeying for a lost one, re-springing a deadlatch or lifting a dropped door. Anything that can wait for a quieter hour, such as rekeying interior doors, is offered as a return visit so the shop floor is not blocked while it trades.
Sometimes, and the visit answers it. A key that failed from its own fatigue in a clean, smooth cylinder says nothing against the lock. A key that broke because the pins were worn flat, the cap had loosened or the keyway was full of grit says the cylinder needs a service or a rekey. One that broke in a corroded, pitted plug is telling you the lock is due for replacement.
Possibly, if the key was part of the cause. A worn or bent key lifts the pins short of the shear line, so the plug binds even in a healthy cylinder, and a copy made from that key repeats the wear. A key cut from the code or from a crisp original is the fix. If the lock was also gritty or the door had moved, the new key would have eased things without settling them, which is why the locksmith checks all three.
A single entry lock that needs cleaning, springs and a strike adjustment is generally done in one visit of an hour or two. Filing a bit key adds bench time, and a set of interior latches is longer simply because there are more of them. A case that needs a part fabricated, or a replacement case that has to be ordered to size, may mean a second visit; the locksmith says so at the assessment.
