- The call
- Your 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.

One key for the front door, another for the back, a third for the side door into the garage, and a fourth for the shed. You stand on the step every evening flipping through them in the dark, trying each one until something turns.
Rekeying is really about knowing who can open your door. Over the life of a home, keys are lent to trades, handed to neighbours for the holidays, given to a cleaner or a dog walker, and copied at the hardware store. Nobody keeps a list. Rekeying draws a line: from today, the only working keys are the ones counted into your hand. Good practice afterwards is simple, and a locksmith will suggest it: know how many keys exist, know who holds each one, tag them with a colour or code rather than the address, and rekey again whenever a key leaves your control.

Lock Rekeying · Caledon

Scene 1
Part of planning a rekey is understanding why it is happening. The locksmith asks how many keys exist as far as you know, who has held one, and whether any went missing with something identifying the address. The answers do not change the pinning, but they shape the advice: whether a padlock or mailbox shares the same risk, whether a garage keypad code should change on the same visit, and how many new keys make sense to cut. It also helps to know whether any key is a restricted or patented type, since those are cut from a record rather than duplicated and may involve the original supplier.
Scene 2
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.
Scene 3
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.

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.
Rekeying is exactly the right response, because it makes the lost key useless at every door that was pinned. The locksmith will walk the property with you to be sure nothing is missed, including the garage side door, a shed and any padlock the same key opened, and will suggest changing any garage keypad code that was written on the same ring. After that, whoever finds the keys is holding brass that opens nothing on your property.
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.
