Rekeying keeps the lock you have and changes only the pins inside the cylinder so a new key operates it and the old one no longer does. It suits hardware that is in good shape and simply needs a fresh key. Replacing swaps the whole lock or cylinder for new hardware, which makes sense when the existing lock is worn, damaged, of low grade, or when you want a different style or a keypad. Either can be done during a lockout visit.

It depends on whose mailbox it is. A private box at your door or on your post is yours, and its small cylinder can be rekeyed or replaced in the same visit. A compartment in a community mailbox or an apartment mailroom belongs to the postal service or the building, which handles lost-key lock changes through its own process. The locksmith will tell you which you have and who to call.

Usually, yes. Most residential doors are prepared to standard sizes, a 54 millimetre cross bore and a backset of 60 or 70 millimetres, and most modern hardware adjusts between those backsets. The locksmith measures before choosing, so the new lock is matched to the door rather than the other way around. Where an older mortise lock or an unusual bore is found, filler plates, extension kits or a carefully jigged new bore bring the door to standard.

Because a shared entry serves more than one household, the locksmith looks for someone with authority over the whole door: an owner, a landlord, a property manager or a condo board, rather than any single resident acting alone. An individual tenant can usually request work on their own unit's door without issue, but changing the lock everyone in the building relies on to get in is treated as a decision for whoever manages the property, with current residents given new keys once it is done.

The mechanism is related but smaller: many mailbox locks use flat wafer tumblers rather than the pin-tumbler cylinders found in most house doors, and some use a tubular, or barrel-key, design instead. The keyway, the tools that open it, and the way it is measured for replacement all differ from a deadbolt, even though both are picked or decoded using similar principles.

Start with what will be inside it. Cash, jewelry, and firearms mainly need protection from tools and time, so the burglary rating matters most. Paper records and digital backups mainly need protection from heat, so the fire rating matters most, and digital media needs a noticeably lower internal temperature than paper to survive. Many households and businesses end up choosing a unit built to both standards rather than picking just one.

It depends on the number of doors and levels involved. A small business with a handful of doors and one or two levels moves through assessment, pinning and testing in less time on site than a multi-floor property with several departments and a top-level master, where more doors, more testing and more keys to cut all add to the work involved.

Often, yes, particularly with an interchangeable-core system where the core is designed to be swapped without removing the lock body from the door. Where the lock body itself is worn, damaged or of a grade that no longer suits the door's traffic, replacing the cylinder alone would leave the underlying problem in place, so the locksmith says which option actually fits the situation found.

Often, yes, for vehicles with a supported conventional key system: the car is opened, a blade is produced by decoding the door lock or retrieving the factory key code, and the immobilizer is reset so the missing keys are erased before new ones are stored. A key-card or phone-key vehicle, or one needing a dealer procedure, follows its own route instead, which is why the VIN is asked for on the first call.
