Why does your remote start stop when the doors are open? A remote start is a feature that allows you to start the engine without going inside the driver seat.
It uses a smartphone app or a key fob to activate. Remote start is helpful, especially during cold weather.
It allows you to warm up your car before you get in so that you can drive comfortably.
However, if you’ve ever used remote start and opened your car door, you may have noticed that the engine immediately stops.
In this article, we will briefly explain why it occurs and what you can do about it.
Why Does the Remote Start Stop When the Door is Opened?
Remote starts are designed with convenience and safety in mind.
One of the safety features that causes the engine to shut off when a door is opened is known as the “door lock/unlock feature” or “door trigger” feature.
It is a common feature in most remote start systems. The feature ensures safety by automatically shutting off the engine when the door is opened.
It is intended to prevent anyone from getting into the car and driving it away without the proper key or key fob.
The remote start feature works by being connected to the door sensors on the car.
If you activate the remote start, the system will send a signal to the car’s computer to start the engine.
However, when a door is open, the sensor sends a signal back to the car’s computer indicating the door has been opened.
Then, the car’s computer will send a signal to the engine to shut off, resulting in disabling the remote start.
The feature is designed to help prevent thefts and accidents. It may happen when someone gets into the car driving it away without a key or key fob.
It also ensures that the vehicle is not left unattended, which is dangerous and can cause damage to the engine.
Why Does the Remote Start Stop When the Door Is Open Important?
This feature is important for several reasons, and it includes the following:
Theft prevention: It is an important feature preventing theft from getting into your car and driving it without key or key fob.
If your engine does not shut off when the door opens, your vehicle might be taken away. Without your notice, the car is gone while you are still warming it up.
Safety Purposes: It ensures that the car is not left running unattended. It is dangerous and also can cause damage to the engine.
It also prevents accidents if someone gets into the car and tries to drive it away without a key or key fob.
If your engine still runs even if the doors are open, it may compromise the security and safety of your vehicle when it’s not you opening it.
Regulation Compliance: Most states have laws and regulations that prohibit leaving a car unattended while running. The feature ensures compliance with those regulations.
Fuel savings: Many people use remote start to warm up their cars during the winter.
This feature helps prevent the vehicle from being left running for extended periods, saving fuel and reducing emissions.
This feature is a common and important aspect of remote start systems.
It is designed to protect the vehicle and prevent potential accidents or thefts while ensuring compliance with laws and regulations.
What to do When Your Remote Start Stop When Doors Are Open?

Some cars have software updates downloadable to disable or bypass the feature.
However, this option may not be available for all vehicles, and the steps may vary based on the car model. Again, check your car’s manual.
Bypass Module
Some aftermarket companies offer a bypass module that is installable to disable or bypass the feature.
These modules are often used for cars that are not intended for a remote start. But can also be used for other vehicles.

What may drain a car battery when it's off are things such as interior lights, door lights, or even bad relays.
