Think about your usual way in
Some households use the front door; others almost always come in from the driveway. Start with the entrance causing trouble, then mention other doors you want included. A side door that sticks should not disappear from the conversation just because the front lock looks newer. Tell us what the key, handle and latch actually do. The lock repair page explains how those observations differ.
Homeowners and tenants have different questions
At an owned home, you may be planning access for family, a neighbor or someone who helps around the house. In a rental, check who is responsible for the private lock and whether permission is required before changes. A shared hallway entrance is a separate matter from your apartment door. Identify each door clearly and involve the property manager where needed, rather than assuming one approval covers the whole building.
A move is a good time to sort the keys
Gather the keys you received and label which doors they open. You may find that two entrances use different keys or that an old spare no longer works. If suitable hardware is in good condition, rekeying may be worth discussing. It changes the operating key without automatically replacing the visible lock. The new-home key guide gives this decision a little more room.
Describe the finish you want
“I want to keep this handle if possible” is a useful preference. So is wanting fewer keys to carry. Whether that can be achieved depends on the condition and compatibility of the existing hardware. Count the doors and the people who need keys, then ask what can be supported. Agree on the work and the estimate before proceeding, including how the finished keys and doors will be checked.
