Moving Into a Los Angeles Home? Lock and Key Checklist

A move-in lock review is not a reason to replace every piece of hardware automatically. Start by restoring control over old keys, separating private and shared openings, and identifying doors that need repair rather than a cosmetic upgrade.

Short answer

Inventory every exterior door, gate, garage entry, mailbox, and shared-access point. Rekey sound compatible cylinders so old keys stop working; repair or replace hardware that is worn, damaged, incompatible, or no longer fits the access goal. Keep common-area changes with the owner, manager, or association.

A move-in check should separate private locks, common access, key control, and hardware condition.

Quick checklist

  • Count exterior cylinders, gates, garage entries, mailbox locks, and detached spaces.
  • Separate private openings from landlord, association, or building-controlled access.
  • Test each lock normally with the door open and closed and note binding or loose trim.
  • Decide which compatible doors should share a key and how many new keys are needed.
  • Photograph each opening and label it before requesting a door-by-door quote.

Start with an opening inventory

Walk the property and list the front, side, patio, garage, gate, accessory-unit, and detached-building openings. Count cylinders rather than only doors because one door can contain more than one keyed lock.

Label photos by opening and include the exterior face, interior trim, door edge, latch or bolt, and strike. Keep actual keys, codes, identification, and security documents out of public messages.

Rekeying and replacement solve different problems

Rekeying changes which key operates a compatible cylinder. It is often the efficient move-in choice when the hardware functions correctly and the security goal is to stop unknown copies from working.

Replacement changes the hardware. It becomes more relevant when a lock is damaged, worn, incompatible, missing required functions, or part of a door that needs broader correction.

Treat shared access separately

Apartment lobbies, common gates, mailrooms, shared garages, and association-controlled openings do not belong in the same decision as a private unit door. A tenant or buyer may have a right to use an opening without authority to alter it.

Ask the responsible property contact which keys, credentials, remotes, or codes should have been transferred and how lost shared-access items are handled.

Create a usable handoff

Confirm the number of supplied keys, which doors each key operates, and whether any openings intentionally remain separate. Test every approved change before the visit ends.

For smart locks, record the exact model, reset administrative access, remove previous users where supported, and keep a private battery-failure and mechanical-backup plan.

Questions people ask

Should every lock be replaced after moving?

Not automatically. Sound compatible locks can often be rekeyed so old keys stop working. Replace selected hardware when condition, fit, compatibility, or the desired function justifies it.

Can all exterior doors use one key?

Possibly, when the cylinders use compatible keyways and remain serviceable. Mixed brands or specialty hardware may require selected cylinder changes or separate keys.
