Locked out with the car running

First: is anyone inside?

Everything else on this page waits until you have answered that question.

• A child, or an adult who cannot let themselves out: call 911 now. Say clearly that a person is locked in a vehicle. Emergency services prioritise it and can open the car. Do not wait on a locksmith.
• A pet: call 911 or animal control. California addresses this in Penal Code section 597.7, which prohibits leaving an animal in an unattended vehicle in conditions that endanger its health or well-being, and which sets out the specific circumstances in which a member of the public may remove the animal — including reasonably believing the animal is in imminent danger, confirming the vehicle is locked and there is no other reasonable means of removal, contacting law enforcement or 911 before entering, using no more force than necessary, and remaining with the animal in a safe place until responders arrive. Civil Code section 43.100 provides immunity from civil liability for damage to the vehicle where that procedure in section 597.7 is followed. That is general information, not legal advice, and the first call is still 911.
• An enclosed space: shut the engine down as soon as you can get to it. A running engine in a closed garage produces carbon monoxide, which you cannot see or smell. If the car is in an enclosed structure, treat it as urgent, open everything you can and get people away from the space.

If the car is outdoors, empty and has fuel in it, take a breath. This is an inconvenience, not a crisis. The main clock running is the fuel gauge.

Then work through this list

1. Try every door. All four, plus the trunk or tailgate. Central locking does not always do what you assume, and rear doors are missed constantly.
2. Try the trunk release. On many cars with folding rear seats, an open trunk is a way into the cabin.
3. Try the manufacturer's app. If the car has connected services and your account is active, remote unlock is often a button away.
4. Find the spare. At home, at work, with a partner, in a bag. Somebody bringing it to you is usually the quickest way out of this.
5. Check whether the fob is actually inside. People call locksmiths from beside cars with the fob in a back pocket more often than you would believe.
6. Then call a locksmith. Give the year, make and model, the exact location, and say that the engine is running.

What not to do

• Do not break a window. Side glass is tempered and does not break neatly — it showers the cabin with fragments that live in the seat rails and the carpet for years. You get cut, you drive with plastic sheeting taped to the door, and you pay for glass, a door card and often a window regulator. All to save a call.
• Do not push a coat hanger down the window seal. The inside of a modern door is packed with wiring looms, the window regulator, speaker wiring and side airbag sensors. Hooking blindly through the weather seal damages the seal itself, scratches the paint on the frame, and can foul the airbag circuit — which is a dashboard warning light and a workshop visit.
• Do not use a slim jim you watched a video about. The tool predates the way modern doors are built. On a car with side airbags and door wiring, it does damage that costs far more than the opening.
• Do not believe the tennis ball trick. It does not work. It has never worked. A ball pressed against a lock cannot transmit anything to a car's central locking.
• Do not force the door away from the frame with a wedge and a screwdriver. Amateur wedging bends the door skin at the top corner, and a bent door never seals properly again.
• Do not leave the car unattended with the engine running while you go home for the spare. Stay with it, or ask somebody to bring the key to you.

When it is a call-a-pro moment

• There is no spare within reach and no app.
• The fuel gauge is low and the engine has been running a while.
• The car is somewhere you cannot leave it — a loading bay, a fire lane, a live traffic lane.
• It is late, you are alone, or you are somewhere you do not want to stand around.
• Anyone or any animal is inside — but 911 first, always.

What a locksmith actually does

1. Checks that the car is yours before touching it — photo identification and something linking you to the vehicle. If the documents are locked inside, say so on the phone and there is nearly always another way to establish it.
2. Reads the door. Different vehicles want different approaches, and the point is to pick the one that leaves no trace.
3. Protects the door. A padded wedge creates a controlled gap at the top of the frame without bending the skin, and the paint is protected where the tool passes.
4. Works the mechanism, not the glass. A long-reach tool operates the interior handle, the lock button or the unlock switch — the same actions you would perform if you were sitting inside.
5. Checks the door afterwards. Seal seated, glass moving freely, no marks.

The whole thing is usually a short visit. If the fob turns out to be lost rather than locked in, that becomes a different job — see what to do when you have lost every car key.

So it does not happen twice

• Have a spare made and keep it out of the car. The single fix for this entire page. Our car key replacement page covers what is involved.
• Learn what your car does automatically. If it locks itself when a door closes, you now know to check the seat before you shut it.
• Set up the manufacturer's app while you are sitting at home. It is useless as a plan you start in a car park.
• Get into the habit of the fob in a pocket, not the cup holder, not the passenger seat, not on top of the roof.
