Why Does My Car Engine Still Running After Key Removed?

There are many reasons why the engine of your vehicle keeps running after you turn off the key and remove it from the ignition.

The most common reason is when you leave a door open, or your car is in gear. If your engine keeps running because you left an open door, simply close the door and restart the car.

If your car won’t start after turning off the key, check to see if it’s out of gas by looking at your gas gauge. If there’s no gas in the tank, fill up before trying again.

Try putting something like a broom handle between the brake and accelerator pedal to keep them apart so they won’t move at all while you’re driving around looking for help.

This will ensure that nothing happens accidentally while you’re out on the road looking for assistance.

What is the cause of this problem?

There are several reasons why your engine may continue to run after the ignition key has been removed. One of them is the electronic throttle control, which can be programmed to stay on for a set period after the driver leaves the vehicle.

This feature is designed to allow drivers to leave their cars running but unattended, such as when they are leaving their car in a parking garage or fueling at a gas station.

Another reason for this issue can be an electrical short, which occurs when two wires come into contact with each other and generate an electrical current. This can happen if there is corrosion or rust on one or both of the wires and they touch each other during operation.

There may be a problem with your ignition switch, which could have failed due to wear and tear or exposure to extreme temperatures over time. If this is the case, you should consider replacing it with an equivalent part so that it functions correctly again without any issues in future use.

Explain how the car’s engine works

The engine in your car is a marvel of engineering. It’s made up of many different parts, but the basic principle is that it’s like a tiny combustion engine that runs off the fuel you put in your tank.

When you turn the key, it sends electricity to the spark plugs, which ignite gas and air as they ignite from the heat of the spark plug. This causes a pressure wave inside your engine that pushes on pistons, which move up and down at high speeds.

The pistons provide power for your vehicle by moving a crankshaft attached to other engines that drive other parts of your car’s systems.

What is the reason for this phenomenon?

The reason for this phenomenon is the fact that even if you remove the key from the ignition, the car’s engine will still run. This is due to a small electric motor and battery in the vehicle’s cabin which powers an idle-stop system.

This system allows the car to be turned off without having to fully shut down the engine. The engine will continue to run as long as there is gas in the tank and no other electrical devices are being used in the car.

Steps to solve the problem

The first thing you should try is simply turning off the ignition. It’s possible that your vehicle has an anti-theft feature, and when you remove the key from its ignition, it automatically turns itself on again by default.

To turn off this feature, press and hold down the “ignition” button on your steering column for 10 seconds. You should hear a click when it’s turned off.

If that doesn’t work, check to make sure that your headlights are not turned on, as they can drain power from your battery and keep it running for longer than expected.

If your lights are off and your engine is still running, check under the hood for any loose cables or wires these could be causing your vehicle to keep running after the removal of the key.

What are the benefits of this solution?

It is a convenient solution for drivers who want to save time by not having to turn off their car engines themselves. This solution will be helpful for drivers who have difficulty turning off the engine, or who tend to forget to do so.

This solution will help protect the environment by reducing car emissions by up to 90%. This solution is easy to install and requires no additional tools or maintenance beyond that of your existing vehicle’s battery and charging system.


The conclusion is that the engine will continue to run for several minutes after the key is removed from the ignition. This is because of a device called an inertia switch.

The inertia switch stops the engine when there is no weight on the pedal or brake, so it can be assumed that your car will not move when you turn off the engine.
