Lock Rekeying
Three months of renovation are finally done.
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 goesOne 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.

How the visit goes
The condition of every cylinder
A cylinder about to be pinned to a new key should be worth pinning. The locksmith turns the existing key in each lock and feels for a plug that drags, soft springs, a wobbling cam or a keyway packed with grit and old oil. A cylinder in good order is rekeyed as it is. A worn one is cleaned and given fresh springs while it is apart, and one that has truly worn out is pointed out so you can choose a replacement rather than have new pins dropped into a tired lock. A bolt that binds against its strike gets noticed here too, so the strike can be adjusted while the locksmith is at the door.
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.
Knowing when to rekey again
Rekeying is not a once-in-a-lifetime event; it is a habit tied to changes in who holds keys. The moments to think about it are the same ones that brought you here: a move, a tenant or roommate change, a key lost with anything identifying the address, a contractor who has finished, or a relationship that has ended. Between those events there is nothing to schedule. Because the house is now on a known system with a record, a later rekey is a shorter visit, and any new lock you add along the way can be pinned to the existing key so the household never drifts back to a ring full of mismatched keys.

What affects the quote
Access 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.
Condition 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.
Number 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.
What to have ready
- How many new keys will your household or your tenants need?
- Do you have a working key for every lock, or is there a door with no key at all?
- Do you own the home, rent it, or manage it for someone else?
Lock Rekeying: questions
QuestionsOne of my locks is stiff and worn. Can it still be rekeyed?
Often the stiffness is grit, old oil and tired springs rather than real wear, and those are handled while the cylinder is on the bench: the plug is cleaned, new springs go in with the new pins, and a dry lubricant finishes it. If the plug has worn oval or the housing is damaged, the locksmith shows you and suggests a replacement cylinder pinned to the same key, rather than fresh pins in a lock that will keep dragging.
What should I have ready before the locksmith arrives?
A list of the doors you want included, a working key for each lock if you have one, and a clear idea of whether you want everything on one key or some doors kept separate. Have your identification and something tying you to the address handy. If you rent, have your landlord's agreement ready to mention. Knowing roughly how many new keys the household needs saves a second trip to cut more.
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.
