What to do if…
you notice your spare key may have been accessed or moved without your permission

Short answer

Treat this as a possible unauthorized entry: get to a safe pause, and if there’s any chance someone is inside or nearby, call 911; otherwise report it to local police (non-emergency) and rekey/change your locks as soon as possible.

Do not do these things

  • Don’t go inside to investigate if you feel unsafe or anything else looks off (door/window ajar, strange noises, items moved).
  • Don’t confront or threaten someone you suspect right now (it can escalate and reduce your safety).
  • Don’t keep using the same lock/key setup “until you’re sure”.
  • Don’t post identifying details publicly (address, where the spare key was, your routines).
  • Don’t handle or “reset” a disturbed scene if you may want police to take a report (leave things as-found where practical).

What to do now

  1. Move to a safer pause first.
    Step away from the door. Go to your car, a neighbor’s home, a lobby/front desk, or a well-lit public place where you can make calls.

  2. Choose 911 vs non-emergency based on immediate danger.

    • Call 911 if you think someone may still be inside, you hear movement, or you feel in danger.
    • If it seems non-urgent but suspicious, contact your local police non-emergency line (or online reporting, if offered). If you don’t know the number, look up the city/county law enforcement agency where the incident occurred and find their “non-emergency” contact.

  3. Do a quick external check only.
    From outside: look for fresh damage around the lock, a door not closing properly, open windows, or other entry points disturbed. If you see clear signs of a break-in, stay out and call police.

  4. Rekey or replace exterior locks ASAP (same day if you can).

    • Rekeying changes what key works without replacing all hardware and is often quicker/less expensive than full replacement, depending on your lock and hardware.
    • If the lock/door is damaged, replace the lock.
      Until that’s done: keep doors locked, stay in one room if you’re inside, and consider having a trusted person with you.

  5. Neutralize the spare-key method you used.

    • If it was hidden outside: remove it and assume the hiding spot is “known”.
    • If it was in a lockbox/key safe: remove the key, change the code, and consider relocating the box to a less visible spot.

  6. If you rent: notify the landlord/property manager in writing and request key control immediately.
    Ask for:

    • who has keys (staff/maintenance/vendors)
    • whether anyone accessed the unit recently and why
    • an urgent plan to rekey/replace locks
      Entry/notice rules vary by state and lease—keep the message factual and focused on safety and key control.

  7. Secure other access points you might overlook.
    Change alarm/keypad codes, update smart-lock credentials, remove unknown app users, and consider changing garage codes or gate fobs if they’re tied to home access.

  8. Document what you observed.
    Take photos of the spare-key location and door/lock area. Write down dates/times (last known normal, when you noticed the change). Keep a simple list of people who legitimately had access.

  9. If anything is missing or damaged, contact your insurer after you’ve made a report.
    You can start by asking what documentation they need. Don’t rush into a claim if you’re still unsure—just keep your notes and photos.

What can wait

  • You do not need to figure out who did it right now.
  • You do not need to decide today whether to move, buy a full alarm system, or make major upgrades.
  • You do not need to confront a neighbor, roommate, staff member, or landlord immediately—secure access first.
  • A full inventory of belongings can wait until you’re calmer and the locks are secured.

Important reassurance

This situation can feel intensely personal and unsettling—even if nothing was stolen. Focusing on a few concrete steps (safety pause, report, rekey) is a solid response and often restores control quickly.

Scope note

This guide covers first steps only: immediate safety, lock/key control, and creating a clear record. Any disputes, longer-term security planning, or legal questions can be handled once you’re stable and the property is secured.

Important note

This is general information, not legal advice. If you feel unsafe or in immediate danger, call 911.
