How should a homeowner revoke a contractor's temporary access after work ends?
Make verification part of closeout
Use the manufacturer's documented method to confirm the change reached the lock; arrange an on-site check when necessary without locking out legitimate occupants. Review any service-company account or third-party integration separately. Ask for physical keys to be returned, and discuss rekeying with an authorized locksmith when copies or continued key access are a concern. Do not publish old or new codes in shared project notes.
