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
For landlords and tenants, rekeying is the tidy way to handle a change of occupancy. A departing tenant may have copied a key or simply forgotten to return one, and a fresh pinning means the incoming tenant is the only person holding a working key. Tenancy rules in this province expect a landlord who changes locks to give the tenant a replacement key and a tenant to have the landlord's consent before changing them, so a locksmith asks who is requesting the work and makes sure both sides end up with a key. A small record of the doors and key count keeps everyone clear.
How the visit goesThe 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.

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.
Taking the cylinder out of the lock
Each type of lock releases its cylinder in its own way, and the locksmith works door by door, finishing one before opening the next, so every entry stays lockable throughout. On a knob or lever set, the handle comes off after a retaining clip or set screw is released, and the cylinder slides out of the handle. On a deadbolt, the interior thumb-turn and housing are removed and the cylinder is withdrawn from the outside body. On an older mortise lock, a small set screw on the door edge is backed out and the cylinder unthreads from the case. Nothing is pried or forced; the door and trim stay untouched throughout.
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
1Travel to the property
Every visit includes the drive. A home across town and a rural property at the end of a long road involve different travel time, and the quote reflects the trip as well as the bench work.
2Records, tags and labelled key sets
A homeowner needs a short note. A property manager may want a keying chart, tagged sets for each suite and a key-issuance log, which is more office work and is quoted as such.
3Mailboxes, 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.
Lock Rekeying: questions
How is rekeying different from replacing the lock?
Rekeying keeps your existing deadbolt or handle set and gives it a new key, commonly by changing the pins inside, though some cylinders reset a different way. Replacing removes the whole lock or cylinder and fits new hardware. Rekeying suits locks that are in good condition and simply need a fresh key. Replacement is the better call for hardware that is worn or damaged, built to a low grade, on a keyway the other doors cannot share, or due for a change of style or a keypad.
Should I rekey when I move into a new home?
It is the single most common reason to rekey, and a sensible one. A resale home has typically passed through owners, agents, inspectors, cleaners and trades, any of whom may have had a key cut. A newly built home has been opened by construction crews using a builder's key. Rekeying on move-in means the only working keys are yours, and the same visit can bring every exterior door onto a single key, retiring the assorted keys you inherited.
I rent. Can I have my locks rekeyed?
Yes, with your landlord's agreement, which is what the tenancy rules here expect before a tenant changes a lock. Most landlords are glad to consent when a key has gone missing or a former roommate has moved out, and the locksmith will want to hear that the landlord knows and will be holding one of the new keys. The rekey itself runs the same as for an owner, and a short note listing the doors done is handy to pass to the landlord.
