Use this landlord checklist to manage keys, codes, shared entrances, and lock rekeying after a tenant leaves a San Carlos rental property.
A tenant turnover creates more than a key handoff. Former occupants, household members, contractors, and previous property managers may have had copies or access codes. Rekeying after a lawful move-out gives a landlord a clear starting point for managing who can enter. This checklist focuses on prevention, recordkeeping, and practical access decisions for rentals in San Carlos and nearby communities.
Before calling a locksmith, list every place a departing tenant could access. Think beyond the apartment’s front door: include a rear entrance, garage, shared lobby, side gate, storage room, mailbox, and any detached shed or utility area. For each one, note the type of lock and who currently holds a key or code.
Ask for keys and access devices during the normal move-out process, but do not rely on their return as proof that no copies exist. Keys can be duplicated, and a former occupant may have shared them. Record what was returned, what appears to be missing, and whether the departing tenant had access to any shared systems. This information helps the locksmith and property manager plan the work without overlooking an entry point.
Not every access point should be handled the same way. A unit lock may need rekeying for a single incoming household, while a building entry or gate may serve multiple residents. Changing a shared lock without an access plan could prevent current residents or authorized workers from entering.
Identify the person responsible for each shared door and confirm how new credentials will be distributed. If the building uses a master-key system, explain that to the locksmith before any work begins. A technician can assess whether the existing arrangement should remain or whether specific locks can be rekeyed without affecting other approved access. Keep separate records for tenant keys, management keys, and restricted service access.
Rekeying a compatible mechanical lock changes which key operates it; it does not necessarily address other ways someone can enter. Check keypad codes, smart-lock users, mobile app invitations, garage remotes, building fobs, and connected access accounts. Remove credentials that are no longer authorized and change administrator access when appropriate.
For electronic locks, follow the manufacturer’s instructions and make sure the owner or property manager controls the main account. Confirm that former users no longer appear in the authorized-user list. If the system is connected to a home network or property platform, review its access history and security settings. Keep a secure record of current administrators, but do not write sensitive codes on a key tag or leave them in an unlocked unit.
Rekeying is often a practical turnover measure when existing locks work properly and are compatible with the new key plan. Replacing hardware may be appropriate if a lock is worn, damaged, difficult to operate, or unsuitable for the property’s security needs. A professional inspection can identify whether a lock can be rekeyed and whether the door, strike plate, and latch function correctly.
Consider usability as well as security. A deadbolt should extend fully into its strike, and the door should close without forcing the key or handle. If a lock is electronic, check battery condition and confirm that a reliable backup method is available. The goal is dependable access for the next resident, not simply a new key that fits a poorly functioning door.

When requesting landlord locksmith services, share the door inventory, any master-key details, and the distinction between private and shared access. Arrange for an authorized person to be present and able to identify each opening.
After the locksmith finishes, test each lock and confirm which keys operate which doors. Distribute keys only to authorized people, and record the recipient, date, and access level. Keep a controlled spare in a secure location. Avoid labeling a key with a full property address or leaving copies where a former tenant or visitor could find them.
A consistent routine reduces missed doors and unclear key records. Use the same inventory at each vacancy, update it when locks or codes change, and verify that the next resident receives working access. Include a final walkthrough for locks, windows, garage entry, and shared doors, while respecting any applicable legal requirements for the tenancy and move-out.
Most importantly, distinguish ordinary turnover work from a disputed possession situation. Do not use lock changes to pressure a tenant or bypass required legal procedures. When possession or access rights are uncertain, obtain qualified legal guidance before changing locks. With a documented process and professional locksmith support, landlords can restore security while keeping access organized for residents and property staff.
