Lock Rekeying
The previous owners left a coffee tin of keys on the counter, some labelled, most not. The house is yours now, but you have no idea how many copies were cut over the years or who still has one in a drawer somewhere.
Lock Rekeying
In plain words
What you keep after rekeying is almost everything. The deadbolt, the handle set, the finish that matches your door hardware, the strike plate and the holes in the door all stay exactly where they are, which matters on an older door where new hardware rarely lines up with old mortises. What changes is a handful of brass pins a few millimetres long inside each cylinder, and the key in your pocket. The work is done on site, one cylinder at a time, so the house is never left with an unsecured door, and worn springs or a sticky plug can be dealt with while the cylinder is already apart.
How the visit goesYour roommate moved out last weekend. Rent is settled, the room is empty, and the key is still on their ring. You trust them, but the lock on your front door should answer to the people who actually live here.

How the visit goes
Smart locks and user-rekeyable cylinders
Modern hardware gets its own look. Many keypad or app-controlled deadbolts have a conventional override cylinder behind a cover that can be rekeyed to the house key so the backup key is not a stranger on your ring, though some models are key-free and use an external battery backup instead. Some residential cylinders are designed to be reset by the owner with a small tool and a working key; the locksmith checks whether one has been reset correctly and whether it accepts the new key. Where a smart lock is being kept, codes are reviewed at the same time so a departed keyholder's code goes the way of their key.
Proving the old keys are finished
The last operation at every door is the test that matters most. The locksmith turns the new key from outside and inside with the door open, then closed, and confirms the bolt throws fully and draws back cleanly. Then the old key is tried in the same cylinder and must turn nothing. This is repeated at every rekeyed door, because the door that gets skipped is the one an old key still opens. Spares cut from the new pinning are tried in every lock they are meant for. The old keys, now just shaped brass, are collected or handed back to you for the recycling bin.
For landlords: the tenant's copies and the paperwork
After a rental unit is rekeyed, the incoming tenant receives their keys, the landlord keeps a copy as the tenancy rules expect, and the number issued is written on the move-in record so the count at move-out is easy to check. The former tenant's keys are retired. Where a building has several suites, the locksmith can keep each on its own key while the shared entry stays on a common one, and the note of which key belongs to which door becomes the start of a keying chart. That chart is what makes the next turnover a matter of one cylinder rather than a guessing game about who has what.

Same fees day, night or weekend
1Access to each door being rekeyed
A rekeying visit goes smoothly when every door is reachable without delay: an empty unit, a cleared hallway, or someone available to let the locksmith into each room. Locked common areas, tenants who are out, or furniture blocking a cylinder all add time the locksmith accounts for on site.
2Mailboxes, padlocks and cabinets
Small cam locks on mailboxes and cabinets are usually replaced rather than repinned, and padlocks vary in whether they can join the house key; each of these is priced as its own item.
3Upgrades chosen during the visit
Some people take the opportunity to replace a double-cylinder deadbolt with a thumb-turn model, add a reinforced strike or move to a heavier deadbolt. None of it is needed to rekey; each is a separate line.
Lock Rekeying: questions
My house is older and has a mortise lock. Can that be rekeyed?
Yes. A mortise lock, the kind with a large case set into the edge of the door, uses a threaded cylinder held by a set screw reached from the door's edge. The cylinder unthreads, is pinned like any other and screws back in. Where a very old lock uses a bit key or a lever mechanism instead of a pin cylinder, the locksmith will explain the options, which may include fitting a modern cylinder into the existing case so the door keeps its original hardware.
Can the entry door of my condo suite be rekeyed?
Often, but check with your property management first. Condominium corporations have a right to enter a unit on reasonable notice, and without notice in an emergency, and many buildings ask that suite doors stay on a system the corporation can open or that a key be lodged with management. Lobby, garage and locker-room doors belong to the corporation and are theirs to manage. A locksmith will ask about your building's rule and work within it.
Can all my doors be made to work with one key?
Usually, yes. Where the cylinders accept the same style of key blank, each can be pinned to one new combination, so a single key runs the front, back, side and garage doors. A lock from a different keyway family is brought into the group by exchanging its cylinder for a compatible one in the same finish. During the first walk around the property the locksmith reads every keyway and tells you up front which doors can be keyed alike.
