Lock Rekeying
The whole key ring went missing somewhere between the grocery store and the bus. You got back in with the spare, but a set of keys is out there, and you would sleep better knowing they open nothing.
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 basement tenant has given notice, and a new one arrives on the first. The lock on the separate entrance works perfectly well. You simply want a fresh key for the incoming tenant and for the old one to be retired.

How the visit goes
Deciding the key groups
Not every door in a home needs to answer to the same key, and the plan is written down before work starts. Most households want the exterior doors keyed alike so one key does everything. Some want exceptions: a basement suite on its own key, a home office or a storage room that visitors should not enter, a shed on a separate key that can be lent out without exposing the house. The locksmith sketches the groups with you, notes how many keys each group needs and who will hold them, and only then begins removing cylinders. Getting this straight first means no cylinder is pinned twice.
Sliding the plug and changing the pins
With the cylinder in hand, the locksmith removes the cam or tailpiece from the back, inserts the existing key and turns the plug slightly so the top pins clear, then pushes a plug follower in behind the plug as it slides out. The follower holds the top pins and springs in the housing so nothing springs loose. The plug now sits on the bench with its row of bottom pins exposed, and those pins are tipped out. This is the heart of rekeying a pin-tumbler cylinder: the pins that decided which key worked are gone, and the plug is ready to receive a set that matches a key nobody has ever carried.
Looking after a freshly pinned cylinder
A cylinder that has just been rekeyed turns as smoothly as it ever will, and a little care keeps it that way. Once or twice a year, a puff of whatever lubricant the cylinder maker specifies into the keyway and a few turns of the key is all it needs, since some current cylinders use oil while too much graphite can itself gum a cylinder. When you need more copies, cut them from one of the locksmith's originals rather than from a copy, because each generation drifts a little from the true depths. A key that starts to need a jiggle is the cylinder asking for a clean and a new key, not a sign of anything serious.

What affects the quote
Same fees day, night or weekend
1Condition of the existing cylinders
A clean cylinder is repinned as it is. One with collapsed springs, a plug packed with old oil or a worn housing needs service or replacement while it is apart, and that shows separately.
2Restricted or high-security cylinders
Patented keyways use controlled blanks and pins that cost more than standard ones, and their keys are produced from a controlled record instead of being copied, so a system of that kind is quoted differently from builder-grade hardware.
3One key group or several
Keying every door alike is the simplest plan. Setting up separate keys for a basement suite, an office or a shed adds a group to pin and label, and the quote shows that as separate work.
Lock Rekeying: questions
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.
How long does a rekeying visit take?
It scales with the number of cylinders and how many need attention beyond pinning. A single deadbolt is a short bench job; a whole house with five or six exterior cylinders, a couple of swaps for mismatched keyways and a set of spares to cut and test takes a good deal longer. Tell the locksmith how many doors you want included when you book, and the visit can be planned realistically rather than guessed at.
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.
