The 2021 Chevrolet Silverado has captured the hearts of many truck enthusiasts with its robust design, powerful performance, and innovative features. One such feature, the remote start system, offers convenience and comfort by allowing you to start your truck from a distance, ensuring a comfortable cabin temperature before you even step inside. However, like any technology, it can sometimes malfunction. If you’re struggling with your 2021 Silverado remote start not working, you’re not alone. This guide will explore common issues, potential solutions, and helpful tips to get your remote start functionality back on track.
Understanding the Remote Start System
Before diving into troubleshooting, it’s essential to understand how the remote start system in your Silverado works. The remote start feature can be activated using the key fob or the myChevrolet mobile app. When initiated, the system triggers the engine to start, allowing the climate control system to reach a desired temperature, whether it’s cooling down or warming up.
Common Causes of Remote Start Issues
If your 2021 Silverado remote start is not working, several factors may be at play. Let’s explore some of the most common issues.
1. Key Fob Battery Problems
One of the most frequent culprits when a remote start fails is a weak battery in the key fob. If your key fob’s battery is low, the signals may not reach your vehicle effectively, which will prevent the remote start feature from activating.
2. Vehicle Safety Features
Chevrolet integrates several safety features into the Silverado, which can inadvertently affect the remote start function. For example, if the vehicle is not in “park”, or if a door is ajar, the remote start may not engage. These safety measures are designed to prevent accidental starts while maintaining high safety standards.
3. Engine Issues
If your vehicle’s engine is experiencing a problem, such as low oil levels, overheating, or issues with the battery, the remote start may be disabled. This safety mechanism is in place to avoid causing further damage to the vehicle.
4. System Malfunctions
Like any electronic system, the remote start feature may encounter malfunctions. Software issues or hardware failures could also be a root cause of your problem.
Troubleshooting Your Silverado Remote Start
If you find yourself facing the remote start issue, follow these troubleshooting steps to identify and resolve the problem.
Step 1: Check the Key Fob
Before anything else, check the condition of your key fob:
- Replace the battery: The most basic yet effective solution is to replace the battery in your key fob. A new battery can restore full functionality.
- Test the key fob: Stand close to your Silverado and try using the lock and unlock buttons. If these are also unresponsive, the key fob may be the issue.
Step 2: Ensure Proper Conditions for Remote Start
Make sure your vehicle meets the criteria for remote starting:
- Check if the vehicle is in “Park”: The remote start will not work if the transmission is not in the correct position.
- Verify all doors are closed: Ensure that all doors, including the tailgate, are securely shut.
Step 3: Inspect Vehicle Health
Examine if any of the following issues might be affecting engine performance:
- Look for warning lights on the dashboard, indicating engine trouble or other system errors.
- Check engine oil levels and ensure proper fluid conditions if applicable.
Step 4: Review Vehicle Settings
Sometimes, user settings may interfere with the remote start feature:
- Navigate through your vehicle’s settings using the infotainment system. There may be options that customize the remote start function—ensure it is enabled.
Step 5: Visit Your Chevrolet Dealer
If you’ve gone through the troubleshooting process and the remote start still isn’t functioning, it may be time to consult a professional. A visit to your Chevrolet dealer will allow a certified mechanic to diagnose and resolve more complex issues involving software or hardware failures.
Preventive Measures for Future Issues
Once the problem is resolved, it’s a great idea to take measures to prevent future remote start issues.
Regular Maintenance
- Schedule routine maintenance check-ups for your Silverado to keep all systems in optimal health. This includes checking the battery, engine oil, and electrical systems.
Key Fob Care
- Protect your key fob from damage by keeping it in a safe place and ensuring the battery is replaced proactively.
Understanding Feature Limitations
While the remote start function is impressive, it’s essential to understand its limitations.
1. Weather Conditions
Extreme cold or hot weather conditions can affect the remote start system’s performance. For instance, if temperatures drop extremely low, the remote start may not operate to protect the engine from harm.
2. Distance Limitations
The range of the key fob is generally about 200 feet. If you are out of this range, the signal won’t reach the vehicle. Similarly, obstructions between you and your vehicle can weaken the signal.
The Role of the myChevrolet Mobile App
For those who prefer mobile technology, the myChevrolet app provides added convenience. You can utilize the app to start your truck remotely, check vehicle status, and even locate the vehicle.
Utilizing the myChevrolet App for Remote Start
To ensure the app functions correctly:
- Confirm that you have a good internet connection on your smartphone.
- Check that your Silverado is equipped with the necessary features enabled in the app settings.

What should I do if my 2021 Silverado remote start is not working?
If your remote start feature isn’t working, the first step is to ensure that you have your key fob with you, as it needs to be within range for the system to function. Additionally, check the battery of your key fob; a weak or dead battery may prevent the signal from reaching your truck. Verify that the vehicle is in park and that all doors, the hood, and the tailgate are closed securely.
Next, it is important to check your vehicle’s settings. Some Silverado models have a setting that disables the remote start feature. You can access this setting through the infotainment system or the vehicle settings menu. If everything appears normal and the remote start is still not functioning, consider consulting the owner’s manual or contacting a Chevrolet dealership for professional assistance.
How can I tell if the remote start system is enabled on my Silverado?
To determine if the remote start system is enabled, start by checking your vehicle’s settings in the infotainment system. Navigate to the ‘Settings’ menu and look for an option related to vehicle features or remote start. Here, you can confirm whether the remote start feature is turned on. If you cannot find the settings, consult your owner’s manual for explicit instructions.
Additionally, most vehicles will provide feedback through the key fob itself. Pressing the remote start button will typically activate the vehicle’s lights or horn briefly if the system is enabled. If there is no response when you press the button, it may indicate that the remote start feature is turned off or malfunctioning.
Can I use the remote start feature if my truck has low fuel?
Generally, the remote start feature on your 2021 Silverado will not work if the fuel level is critically low. The system is designed to prevent starting the vehicle if it detects that fuel levels are inadequate for operation. Typically, the vehicle needs to have a minimum level of fuel to perform a remote start successfully, ensuring you won’t be stranded with an empty tank.
If you find yourself unable to use the remote start due to low fuel, it’s advisable to refuel your truck. After refueling, you should be able to use the remote start feature again, assuming there are no other underlying issues. Always keep an eye on your fuel level to avoid this inconvenience.
Why does my 2021 Silverado automatically shut off after starting remotely?
Your Silverado may shut off automatically after a remote start for several reasons, with the most common being that safety features are in play. If any doors are opened or if the truck is shifted out of park during the remote start, the system is programmed to turn off for safety reasons. This feature is designed to prevent unauthorized use of the vehicle while it’s running unattended.
Another potential reason is that the system may detect an issue with the engine, such as low oil pressure or an overheating condition. In such cases, the remote start will engage but then shut off to protect the vehicle from further damage. If this happens frequently, it’s worth getting your vehicle checked by a professional to identify any underlying mechanical issues.
Is there a maximum distance for using the remote start?
Yes, there is a maximum distance for operating the remote start feature on your 2021 Silverado. Typically, the effective range for the remote start is around 200 to 300 feet, depending on the terrain and environmental conditions. Physical obstructions such as buildings and hills can interfere with the signal and reduce the operating distance.
If you find that you cannot start your vehicle remotely from a distance you once could, it may be a sign of a weak key fob battery or an issue with the remote start system. Replacing the battery in your key fob may restore the range, but if the distance continues to be limited, consult your vehicle’s manual or a professional technician for further support.
What are some common reasons for remote start failure in the 2021 Silverado?
Several factors can contribute to remote start failure in your 2021 Silverado. One common reason is that the vehicle must be in the park position with all doors closed for the remote start to work properly. If there is an issue such as a door being slightly ajar or the hood not being latched correctly, the system will not engage.
Another issue could be related to the key fob itself. If the fob’s battery is low or if there’s a malfunction with the fob, it may not send the correct signal to start the truck. Additionally, if your vehicle’s engine is experiencing related problems such as warning lights illuminating on the dashboard, the remote start may also be disabled as a precautionary measure.
Can I use my smartphone to start the remote start feature on my Silverado?
Yes, if your 2021 Silverado is equipped with the myChevrolet app and has an active OnStar subscription, you can use your smartphone to start the vehicle remotely. This feature allows you to start your engine, as well as control other functions of your truck from virtually anywhere, provided you have cellular coverage. Make sure that you have logged in to your account and that your app is updated to the latest version.
Before relying on your smartphone for remote start capabilities, check to ensure that your vehicle is configured for this feature. You might need to enable the remote access features through the myChevrolet app or your truck’s settings. If you encounter any issues, refer to the app’s help section or customer support for assistance.
