Lock Rekeying
Three months of renovation are finally done.
In plain words
Moving into a home is the moment most people first hear about rekeying, and it is the most sensible time to do it. A resale house has usually passed through owners, real estate agents, home inspectors, cleaners and trades, each of whom may have held a key at some point. Rekeying every exterior cylinder on move-in day means the only keys that work are the ones cut for you, and the same visit is a chance to put every door on one key so the coffee tin of mystery keys can go in the recycling.
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


Walking every door that should be included
Before a single cylinder comes out, the locksmith walks the property with you and lists each opening: the front door, the back and side doors, the door from the garage into the house, a walkout basement, a gate with a keyed latch, a shed, a mailbox, and any interior door you want on a key. It is surprising how often the garage's side door or the storm door is forgotten and left on the old key. The list becomes the plan for the visit and, at the end, the record of what was done. A door that is not on the list is not rekeyed, so the walk is worth two careful minutes.
When a cylinder is swapped instead of repinned
Sometimes the right move for a particular door is a new cylinder rather than new pins, and the locksmith says so before doing it. A cylinder with a keyway that cannot join the household key is replaced with one that can. A plug that has worn oval, springs that have collapsed, or a cylinder someone has already drilled is replaced because fresh pins would not fix its feel. In each case the replacement is pinned to the same new key as the rest of the house, so the swap is invisible in daily use. The old cylinder is handed to you or taken away as you prefer.
For landlords: the tenant's copies and the paperwork
After a rental unit is rekeyed, the incoming tenant receives their keys, the landlord keeps a copy as the tenancy rules expect, and the number issued is written on the move-in record so the count at move-out is easy to check. The former tenant's keys are retired. Where a building has several suites, the locksmith can keep each on its own key while the shared entry stays on a common one, and the note of which key belongs to which door becomes the start of a keying chart. That chart is what makes the next turnover a matter of one cylinder rather than a guessing game about who has what.

What affects the quote
How many cylinders are included
Each cylinder is removed, pinned and tested on its own, so a single deadbolt and a house with six exterior locks plus a shed and a gate are very different visits, and the quote follows the count.
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.
One 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.
What to have ready
- Do any locks feel stiff, loose or need a wiggle to turn?
- Do you have a working key for every lock, or is there a door with no key at all?
- Has a key gone missing, or is one still held by someone who has moved on?
Lock Rekeying: questions
QuestionsI am a landlord. Should I rekey between tenants?
Many landlords do, and it removes the question of whether every copy came back. The locksmith rekeys the unit's cylinders so the incoming tenant holds the only working keys, cuts the copies you want, and notes the count for your move-in record. Because provincial tenancy rules expect the tenant to be handed replacement keys whenever a landlord changes a lock, the visit ends with keys for both of you and a clear list of which doors were done.
What happens to my old keys?
They become ordinary pieces of brass. Once the cylinders are pinned to the new combination, the old keys turn nothing on your property, so there is no security reason to keep or hide them. Hand them to the locksmith for disposal or drop them in the metal recycling. If a former roommate or contractor still has one, it no longer matters, which is the whole reason for the visit. Keep only the new set, counted and tagged.
Can I keep one door on a different key from the rest?
Yes, and it is common. A basement suite or in-law apartment often gets its own key so the tenant's key opens their door and nothing else, while your key opens the main house. A home office, a storage room or a shed can be kept separate for the same reason. The locksmith sets up the groups you want, pins each accordingly and tags the keys so the separate one is not mixed into the household set.
