How long does my remote start stay on?
Most remote-start sessions stay on for about 10 minutes by default. Some systems run for as little as 5 minutes or as long as 15 minutes, and a few offer longer extensions or multiple cycles. The exact duration depends on the vehicle’s make and model and whether the remote start is factory-installed or an aftermarket unit.
Typical duration ranges
To understand what you’re likely dealing with, here are common duration ranges you’ll encounter with today’s cars, depending on the type of remote-start system in use.
- OEM factory remote start systems typically run for a single cycle of about 5–15 minutes. Most widely used configurations default to around 10 minutes, with some newer models offering a 15-minute option or a longer 20-minute cycle in specific climates or trims.
- Aftermarket remote-start kits and modules commonly run 10–15 minutes per start, with many units offering 20 minutes or more as a configurable option via a timer on the remote or a phone app.
- Climate preconditioning features can influence the effective usage window, especially in cold weather, but the base duration is still governed by the system’s timer. Some setups allow extending the run time through an additional timer or re-initiating a second start after the first ends.
In all cases, it’s best to check your owner’s manual or the vehicle’s app for the exact duration configured for your model, as variations are common across makes and model years.
What affects the duration
Factory-installed (OEM) remote starts
When a vehicle leaves the factory with a remote start, the run time is part of the design and can vary by model year. Most commonly it is a fixed window in the 5–15 minute range, chosen to balance comfort with safety and fuel economy. Some premium or newer models offer a longer 15–20 minute option in certain climates.
Aftermarket remote start systems
Aftermarket solutions range from simple 10-minute timers to more complex setups that allow 15–20 minutes or more. Many aftermarket units let you select a duration via the remote, keypad, or a companion smartphone app. In some cases, you can add multiple cycles by issuing a quick second start.
How to check and adjust the duration
Know your system and how to adjust it, if possible, with these steps:
- Consult the owner’s manual for your specific model and remote-start hardware to locate the default duration and any adjustable options.
- Check the remote or smartphone app for a timer setting (commonly 5, 10, 15, or 20 minutes). Some apps display the current run-time as a status indicator.
- If you have an aftermarket kit, review the installation guide or contact the installer to confirm the configured duration and whether changes are supported post-installation.
- Be aware of safety features and local regulations that could limit idle time, especially if you plan to run the engine in a garage or enclosed space.
If you cannot locate an option to extend run time, the typical workaround is to re-activate remote start after the initial cycle ends. For those needing longer preconditioning, upgrading to a system that supports longer timers is often the practical path.
Safety considerations
Garage and carbon monoxide risk
Never run remote start inside a closed garage or enclosed space. Even with doors open, monitor for any signs of exhaust buildup and ensure proper ventilation. Many jurisdictions recommend against using remote start in enclosed or semi-enclosed areas.
Automation and security features
Some systems automatically shut off if certain conditions occur, such as low battery voltage, high engine temperature, or if the vehicle detects that the key fob is inside the cabin. Others may require you to press the brake pedal before driving, even after the engine restarts via remote start.
Summary
Remote-start durations are not universal; the window is typically between 5 and 20 minutes depending on whether the system is OEM or aftermarket. Check your vehicle’s manual or app for the exact setting, and remember you can often re-activate the system to extend the total warm-up time. For the safest and most comfortable experience, know your system’s limits and never use remote start in a closed space.
How do I change my remote start to run longer?
To make your remote start run longer, you can either repeat the start-up sequence after a short wait or, on some vehicles, extend the run time through the in-vehicle settings or a mobile app. For a key fob, press the lock button and then press and hold the remote start button again, waiting at least 30 seconds after the initial start. On some modern cars, you can adjust the default run time to a longer duration (like 15 minutes) through the vehicle's "Settings" menu under "Remote Start".

Using in-vehicle settings
- Access settings: Once the car is running, use your steering wheel controls to navigate to the "Settings" menu, then "Advanced Settings".
- Find remote start options: Look for "Vehicle" and then "Remote Start," where you will find a "Duration" option.
- Set the duration: Choose a longer time, such as 15 minutes, if your vehicle offers it.
Using a mobile app
- Open the app: Open your vehicle's companion app on your phone.
- Start and extend: Start the vehicle, and within the initial run time, tap the start/stop button again followed by an "extend" button.

Important considerations
- Always ensure the vehicle is in a well-ventilated area, preferably outdoors, to avoid carbon monoxide buildup.
- The exact steps and options vary by manufacturer, so consult your owner's manual for model-specific instructions.
- Some systems have a maximum run time, and you will need to manually start the car to reset the timer.
How long will my car stay on with remote start?
A car will stay on with remote start for a set period, typically 10 to 15 minutes, before automatically shutting off to prevent theft and save fuel. You can often extend this initial run time by remote starting the car again before the first session ends, sometimes allowing a total of 20 to 30 minutes before the vehicle must be manually started with the key.
Standard run time
- Most cars run for a standard 10-minute cycle, but some may offer 15-minute options.
- This time limit is often mandated by government regulations for pollution and fuel efficiency reasons.
Extending the run time
- To extend the time, you can often use the remote start a second time within the initial cycle to add more run time.
- This can sometimes increase the total idle time to 20 or even 30 minutes.
- After the maximum run time is reached, the car will shut off and you will need to start it manually to reset the system.
Security and operation
- For security, the car will shut off if you open the door without the key inside.
- The vehicle will not drive away without the key present, preventing theft.
- You will need to press the brake and the start/stop button once inside to take control and continue driving.
Will my remote start drain my battery?
Yes, remote start can drain a car battery, though a properly installed system from a reputable brand usually only causes a minimal, normal draw. However, issues like improper installation, faulty components, or leaving the car in remote-start mode for too long can lead to a battery drain.
Why remote start can drain the battery
- Parasitic draw: All cars have some level of "parasitic draw," which is power that electronics consume when the car is off, such as the clock or radio presets. Remote start systems add a small amount to this draw to stay in a "listening" mode for the remote signal.
- Improper installation: An incorrect installation can cause more significant battery drain due to faulty wiring or components.
- Component failure: A malfunctioning remote starter or a short in the starter solenoid can cause a continuous, excessive power drain.
- Extended use: Repeatedly using remote start for short periods without a long drive afterward can prevent the battery from fully recharging.
How to prevent battery drain
- Check battery health: Ensure your battery is not old or failing. A weak battery is more susceptible to drain.
- Proper installation: Have the system installed by a qualified professional to minimize the risk of improper wiring.
- Consult the manual: If you have a modern vehicle, check the key fob range and how to keep it from constantly communicating with the car.
- Avoid extended idles: While remote start is convenient, avoid leaving the car idling for extremely long periods without driving it, as idling doesn't charge the battery as efficiently as driving does.
- Troubleshoot the system: If you suspect a drain, have a professional use a multimeter to measure the parasitic draw to see if it is within normal limits or if the remote starter is the cause.
Does remote start shut off automatically?
Yes, a car's remote start turns off automatically, typically after a set period of time, most commonly 10 to 15 minutes. This automatic shutdown is a safety feature to prevent indefinite idling and to ensure a key is present to drive the vehicle. Many systems also have additional safety measures, like shutting the car off if the door is opened without the key fob present, and may require a specific procedure to take control of the car without it shutting off.

Automatic shutdown and other safety features
- Automatic shutdown: The engine will shut off automatically after a preset duration, usually between 10 and 15 minutes, to conserve fuel and for safety.
- Key detection: The vehicle will turn off if you press the brake or try to shift into gear without the key fob present.
- Door opening: Many factory remote start systems will shut off the engine as soon as you open the driver's door. Some newer systems have a "secure takeover" feature, which allows you to get in and drive away after a specific procedure, like pressing the brake and then the start button, without the car turning off.
- Multiple start attempts: Many systems have a limit on how many times you can remote start without getting into the vehicle, often a maximum of two times, before you are required to start it from the inside.

Why this happens
- Safety and security: The automatic shutdown prevents thieves from being able to drive the car away and also acts as a safety measure for the vehicle and its occupants.
- Government regulations: The automatic shutdown is partly mandated by governments as a measure to promote fuel economy and reduce emissions.
