Lock Rekeying
Three months of renovation are finally done. The kitchen looks wonderful, and along the way a general contractor, a tile installer, a plumber and an electrician each carried a key to your front door at one point or another.
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 goesEvery copy of your house key seems to work a little differently. One needs a jiggle, another sticks halfway, and the original wore down years ago. The lock itself is fine; the keys have drifted so far from each other that none fits cleanly.

How the visit goes
Who is entitled to change the locks
Rekeying decides who can enter a home, so the first check is about the person asking. A homeowner shows photo identification and something tying them to the property, such as a tax bill, a closing document or a utility statement. A property manager brings authorization from the owner. A tenant is asked whether the landlord has agreed to the change and will receive a copy of the new key, because tenancy rules here expect both sides to hold one. Where a unit is in a condominium, the locksmith asks whether the building has a rule about suite-door locks. None of this is an obstacle; it is the part of the job that protects the home being worked on.
Reassembly and the shear-line test
On a pin-tumbler cylinder, the plug goes back into the housing with the new key in it, pushing the follower out ahead of it, and the cam or tailpiece is refitted with its retainer. Before the cylinder goes anywhere near the door, the locksmith turns the new key and checks that the plug rotates freely with no catch, then removes the key and confirms the plug is locked solid. A pin a fraction too long or too short shows up here as a rough turn and is corrected on the bench. Only a cylinder that passes goes back into its lock, where it is tested again with the door open and then closed.
Living with one key for the house
If the visit brought your doors onto a single key, daily life gets a little simpler: one key opens the front door, the back, the garage's side entry and the shed, and the ring in your pocket shrinks to the car key and one for the house. Anyone you give a key to gets the same freedom, which is convenient for family and worth thinking about for anyone who should only reach one door; that is what a separate group is for. Keypads and smart locks keep their codes, and their override cylinder now takes the same key. If you add a door later, its cylinder can be pinned to match.

What affects the quote
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.
2Condition 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.
3Number of keys cut
Keys are cut and tested individually, so the total depends on how many the household or the tenants need. Say the number when you book and the quote reflects it from the start.
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.
Can a smart lock or keypad deadbolt be rekeyed?
The mechanical part of it can. Many keypad or app-controlled deadbolts hide a small keyed cylinder under a cap for the day the batteries fail, and that cylinder can be pinned to your house key so the backup key on your ring is the same one that opens the other doors; some models are key-free and rely on an external battery backup instead. Codes are a separate matter: the locksmith will suggest deleting any code belonging to someone who no longer needs access at the same time.
Can the garage side door, shed and gate be included?
Yes, and they usually should be, because a side door into the garage is the opening most often forgotten and left on an old key. Any pin-tumbler cylinder on the property can be pinned to the house key if its keyway allows: the man-door into the garage, a shed, a keyed gate latch, and many padlocks. A mailbox lock is usually a small cam lock that is replaced rather than repinned. Mention every opening when you book so the right blanks and cylinders are in the van.
