What to do if…
a child or pet is locked inside a vehicle

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

Short answer

Move out of traffic but stay close enough to watch the child or pet. Call 999 immediately if they are unresponsive, struggling to breathe, confused, having a seizure, collapsing or otherwise in immediate danger.

Do not do these things

  • Do not put yourself in moving traffic or another dangerous position.
  • Do not leave the child or pet unattended while looking for help.
  • Do not wait for a locksmith or vehicle service if their condition is worsening.
  • Do not assume shade, an open window or mild weather makes a closed vehicle safe.
  • Do not smash a window as your first response; contact the police and explain what is happening.
  • Do not crowd the vehicle or block access for emergency services.
  • Do not focus on blame, repair costs or responsibility while the child or pet may be at risk.

What to do now

  1. Stand somewhere safe where you can continuously see the child or pet. If the vehicle is in live traffic, moving, filling with smoke or exposed to another immediate hazard, call 999.

  2. Try to get a response by speaking to the child or making a familiar sound to the pet. Watch their breathing, alertness, movement and behaviour through the glass.

  3. Call 999 if you have concerns about a child’s health, or if the child or pet is showing signs of immediate danger such as breathing difficulty, confusion, seizure, collapse, loss of consciousness, severe weakness or rapidly worsening distress. Give the location, vehicle registration, make, colour and what you can see.

  4. Check each door and the boot once if it is safe. Use a spare key or immediate remote-unlocking option if available, but do not let this delay an emergency call.

  5. If there are no danger signs and it is your vehicle, contact your breakdown provider or a locksmith while someone keeps watching. If another person’s pet appears alert and not distressed, note the registration and ask nearby staff to locate the owner.

  6. For a non-emergency concern about a pet, call the police on 101 for advice. Call 999 immediately if the pet becomes distressed or shows signs of heatstroke.

  7. Do not force entry straight away. If the danger becomes immediate before help arrives, tell the police what you are considering and why, describe any change in condition, and follow the call handler’s instructions. Forced entry can cause injury and may have legal consequences.

  8. After releasing an overheated child, move them to a cool place, remove unnecessary outer clothing, cool their skin with cool water and airflow, and give water only if they are fully awake and able to drink. Continue following any instructions from the ambulance service.

  9. After releasing an overheated dog, stop further activity and pour water that is cooler than the dog over its body while avoiding the head. Create airflow, call a vet, and follow the vet’s instructions. For another type of pet, contact a vet immediately for species-appropriate advice.

  10. Stay with the child or pet until emergency services, a responsible adult, the owner or veterinary help takes over.

What can wait

Explaining how the lockout happened, arranging vehicle repairs, contacting an insurer, replacing keys and deciding who is responsible can wait. Longer-term changes to childcare, pet care or vehicle security do not need to be decided now.

Important reassurance

Accidental lockouts can happen quickly. Watching the child or pet closely, giving a clear location and seeking the right help promptly are the useful things to concentrate on now.

Scope note

This guide covers immediate release and initial safety only. Medical or veterinary assessment, safeguarding concerns, vehicle damage, insurance and legal questions may require appropriate professional help later.

Important note

This is general information, not medical, veterinary, legal or emergency-service advice. Follow instructions from the 999 call handler, police, ambulance service, fire and rescue service or vet dealing with the incident.
