- 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.

The 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.
One key for the whole house is a common request and usually achievable. Cylinders that share the same keyway, the shaped channel the key slides into, can all be pinned to the same new combination, so the front door, back door and garage entry answer to a single key. Where a door carries a lock from a different family with its own keyway, that cylinder is swapped for a matching one rather than repinned, and then it joins the group. The locksmith checks each lock face before the work begins so you know exactly which doors will share the key.

Scene 1
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.
Scene 2
On this cylinder type, the new key comes first, then the pins to match it. The locksmith cuts a fresh key from a blank on a code cutter or duplicator, choosing a combination that is not close to the old one, and reads each cut with a key gauge to find its depth on the manufacturer's scale. Bottom pins of the matching lengths are picked from a graded pin kit and dropped into the plug chamber by chamber, so that when the new key is inserted every pin top sits exactly at the shear line. A key cut from a clean blank and pins matched to it by gauge is what gives a rekeyed lock that crisp, new feel.
Scene 3
Rekeying gives you a clean start on who holds a key, and a few habits keep it clean. Give a key only to people who need one regularly, and know who they are. If a dog walker, a cleaner or a contractor needs access for a season, a lockbox with a code you can change afterwards is simpler than a key you have to ask for back. Tag spares with a colour or a number rather than the address. When a key does leave your control, a lost ring, a departing tenant, a relationship that has ended, that is the trigger to rekey again, and the next visit is simpler because the doors are already on one system.

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.
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.
Yes, at every cylinder that was rekeyed. Once the bottom pins are changed, a key cut to the old combination lifts them to the wrong heights and the plug will not turn. The locksmith proves this at each door by trying the old key after the new one, because any door missed from the list would still answer to the old key. That is also why the walk around the property at the start matters: every door meant to be included has to be on the list.
