Locked inside a car with a dead battery: How to unlock and escape

Have you been through a situation of getting locked inside a car with a dead battery? If yes, then this post is for you.

Getting locked inside a car with a dead battery may arise if you accidentally lock yourself inside, or if the battery dies while you are inside the vehicle.

In such circumstances, it is essential to know the methods on how to unlock the car and escape successfully.

Door lock/unlock buttons of a car

Electronic malfunction – An electronic malfunction is expected when the battery dies and doors get locked automatically with a dead battery. A glitch or failure in the control module responsible for the central locking system could result in electronic malfunction.

Car’s key system issues – The locking/unlocking of a car door heavily relies on the key system/functionality. Some cars are equipped with a keyless entry system which becomes useless without battery power.

Similarly, a car that is dependent on unlocking the doors with the help of its remote key fob will keep you locked inside the car if the battery inside the key fob dies.

The reasons or causes do not end here and you may get locked inside a car for many other reasons depending on your car’s make and model functionalities. Therefore, make sure you know the specifics of using resources for entering and exiting your vehicle.

Having said that, there are some common steps you can follow to try and escape from a locked car:

Manual lock/unlock – You can try using the manual lock/unlock mechanism to open the door. Generally, such buttons are available inside the door or close to the car window.

While most of the older cars have a traditional keyhole in the car door which can be used with a key to manually unlock the door, you may also unlock the door by just double pulling the interior handle in some premium cars.

Additionally, you will find some cars have an emergency door release lever or button located near the floor, under the dashboard, or on the door itself. You just need to activate this button to unlock the doors which is another way of manually releasing yourself from the car.

Emergency escape tools – If your car make and model does not have a manual unlocking mechanism you will have to look for other ways to come out of the vehicle.

One way to escape the car is by using emergency tools. Specifically-designed hammers, window breakers, or any other sharp metal object/rod can be used to break the window.

When doing this, cover yourself especially the face with clothing to avoid injuries from flying glasses. Aim for the window corners or edges and carefully climb out through the broken window.

Call for help – In the end, if nothing works from the above-mentioned methods then use your mobile phone (if available). Call somebody you know and stay nearby to help you out of this situation.

Alternatively, contact emergency services or a locksmith to seek their guidance on taking the right step under such circumstances.

Remember, staying calm is crucial in emergency scenarios. Instead of panicking, assess your options, and take the necessary steps to escape the vehicle quickly and safely.

The location of such a lever will depend on your car’s make and model and should be clearly mentioned in the instruction manual/booklet.

On the other hand, if you are looking to open the hood of a car with a dead battery from outside then use the manual key to unlock the door and pull the lever. Such manual keys are part of almost every car model designed to use in emergencies.

In case your car model does not have a manual key seek professional assistance or call the locksmith to help you open the hood with their specialized tools and training.

Some of the other alternatives to unlock are using an emergency tool and calling for professional assistance.

Final thoughts

Finding oneself locked inside a car with a dead battery can be a distressing situation. It may not happen to everyone and when it actually happens the causes may differ with every car.

There are several methods to unlock and escape a car with a dead battery. These methods include using a manual door lock, using an emergency tool, breaking a window as a last resort, or seeking professional assistance and using a locksmith.
