Lock Rekeying in Lansing
Three months of renovation are finally done.
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 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.

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.
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
Records, 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.
Smart lock override cylinders and codes
Pinning the backup cylinder of a keypad or app lock to the house key is a small extra task, and reviewing or deleting user codes at the same time is another, each named in the quote.
Travel 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.
What to have ready
- Are any of the locks keypad or smart locks with a backup key?
- Which doors do you want rekeyed, and have you counted the door from the garage?
- Is the home a condo or in a building with shared entrance doors?
Lock Rekeying: questions
QuestionsHow often should locks be rekeyed?
There is no calendar for it. What matters is who holds a key, not how many years have passed. Think about it when occupancy changes hands, when someone who had a key no longer needs one, or when a ring goes missing along with something that shows where you live. Between those moments a well-kept cylinder may need no scheduled care, and when it does, use whatever that cylinder's maker specifies. With the doors already on one recorded system, any repeat is a short piece of work.
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.
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.
