What to do if…
a door lock, peephole, or security camera appears tampered with

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Move away from the doorway and call 999 if someone is in immediate danger, a person may be inside, or a crime appears to be happening now. Otherwise, avoid disturbing the area, photograph what you can safely see, preserve any camera footage, report suspected deliberate tampering, and arrange for the entrance to be secured.

Do not do these things

  • Do not confront, follow, or search for anyone you suspect.
  • Do not enter the property if the door is open, someone may be inside, or entering feels unsafe.
  • Do not stand close to the doorway while examining possible damage.
  • Do not clean, dismantle, repair, or repeatedly test the lock, peephole, camera, frame, wiring, or nearby surfaces before recording their condition.
  • Do not touch unfamiliar objects or areas that may have been handled by another person unless safety makes this unavoidable.
  • Do not switch off a camera, change its settings, or delete footage that may show what happened.
  • Do not factory-reset a camera or its account before relevant footage has been saved or the police have advised you.
  • Do not post images or footage publicly while the incident is being assessed.

What to do now

  1. Reach a safer position. Move to a trusted neighbour, a staffed public place, or a lockable room if you are already safely inside. Call 999 if someone is in immediate danger, you think an intruder may still be present, or the tampering appears to be happening now.

  2. Look without disturbing anything. From a safe distance, note visible changes to the door lock, frame, peephole, camera, mounting, cables, or surrounding area. Do not handle loose parts or unfamiliar objects.

  3. Photograph the condition. Take clear photographs of the whole doorway and closer views of the affected lock, peephole, camera, frame, wiring, marks, and loose parts. Record when you discovered the change and when you last saw the equipment intact.

  4. Preserve recordings. Leave cameras and video doorbells switched on and keep their settings unchanged. Where possible, save footage covering about five minutes before and after the relevant event, while retaining the original recording on the device or service.

  5. Report suspected deliberate tampering. Use the police online reporting service or call 101 if there is no emergency. Describe what has changed, whether the door can still be secured, whether anything appears missing, and whether you have photographs, footage, or possible forensic evidence.

  6. Check whether work was authorised. If the property is rented or managed, contact the landlord, housing provider, concierge, or building manager through contact details you already trust. Ask whether anyone was authorised to alter or inspect the lock, peephole, or camera.

  7. Make the entrance secure. If the door cannot be locked, remain somewhere safe and contact the landlord, building emergency service, or a locksmith. Photograph the damage first and, where practical, ask the police whether repairs should wait; if urgent repairs are necessary, ask the repairer to disturb the affected surfaces as little as possible.

  8. Check the camera account after preserving footage. If alerts, settings, or access records suggest digital interference, use a trusted device to change the account password, enable two-step verification where available, and follow the manufacturer’s security instructions.

  9. Tell a trusted person. Let someone know where you are and what you found. If similar interference has happened repeatedly or appears targeted, keep the dates, photographs, footage, and report details together for specialist safety support.

What can wait

You do not need to identify who caused the damage, confront anyone, replace the entire security system, post a public warning, make an insurance claim, or decide whether to move home now. Focus first on personal safety, preserving what you found, reporting it where appropriate, and securing the entrance.

Important reassurance

Damage or an equipment fault does not by itself establish who caused it or why. You do not need to investigate the situation alone, and taking careful safety and evidence-preservation steps is a reasonable response.

Scope note

This guide covers immediate first steps only. Later decisions about repairs, insurance, tenancy responsibilities, repeated incidents, stalking concerns, or wider security changes may require help from the police, your housing provider, a locksmith, a security specialist, or a specialist support service.

Important note

This is general safety information, not legal or professional security advice. Follow instructions from emergency services and use your judgement about whether it is safe to remain at or enter the property.
