How do you auto start a Chevy Impala?
Remote starting a Chevy Impala is possible through factory remote start on supported trims or via the OnStar/MyChevrolet app; if those options are not available, an aftermarket system can be installed by a professional.
This article explains the main ways to start your Impala remotely, including how to use the built-in remote start on eligible models, how to start the engine from the mobile app, and what to know about aftermarket systems. It also covers safety considerations, run times, and year-by-year differences to help you choose the best option for your car.
Factory remote start with the key fob
If your Impala is equipped with factory remote start, you can start the engine from the key fob without entering the car. Models and trims that include this feature generally follow a consistent sequence, but exact behavior can vary by year. Use the procedure below as a general guide and consult your owner’s manual for year-specific details.
- Lock the doors with the key fob.
- Press and hold the remote-start button (the circular arrow) for 3–4 seconds until the interior lights flash or the engine starts.
- The engine will run for up to a set period (commonly up to 15 minutes) and can be extended by repeating the sequence within the allowed window if your model supports it.
- To stop the engine early, press and hold the remote-start button again for 3–4 seconds, or press the lock button to secure the vehicle.
Note: If the vehicle does not start, ensure the doors are locked, the transmission is in Park, and the hood is closed. A low battery in the key fob or a system fault can prevent remote start from working.
Model-year notes
Factory remote start capabilities and the key fob design can differ by year and trim. Some older or base-model Impalas may not offer remote start at all, while later models may rely on different fob sequences. Always verify with the owner’s manual or your dealer if you’re unsure whether your specific vehicle supports this feature.
Remote start via the MyChevrolet app or OnStar
Many Impalas built in recent years can be started remotely through GM’s OnStar service or the MyChevrolet app, provided you have an active subscription and a linked account. This method is convenient if you’re outside the vehicle or want to precondition the cabin before you arrive.
- Ensure OnStar or the MyChevrolet app is active and linked to your Chevrolet account.
- Open the MyChevrolet app (or OnStar app, depending on your setup) and navigate to Remote Start or Remote Services.
- Select Remote Start and confirm; the app will communicate with the vehicle to start the engine.
- The engine will run for the allotted time and climate control will operate as configured; you can stop the engine from the app at any time if needed.
Safety and eligibility notes: Remote start via the app typically requires the vehicle to be in a safe state (doors locked, parking brake engaged) and, in some cases, may require the key fob to be within a certain range or the vehicle to have a valid OnStar subscription. Always review the latest app prompts and your subscription terms.
App-based limitations
Some regions or account types may impose restrictions on remote starting, and certain features may be limited by vehicle health or battery status. If in doubt, contact Chevrolet/OnStar support to confirm service availability for your exact model and location.
Aftermarket remote start options
If your Impala isn’t equipped with factory remote start or you want features beyond the factory system, an aftermarket remote start can be installed. This option should be handled by a qualified installer to avoid warranty issues and electrical problems.
- Choose a kit that is compatible with automatic transmission, the car’s immobilizer system, and your preferred feature set (one-way vs two-way remotes, smartphone integration, etc.).
- Have the system installed by a professional installer who understands GM wiring and anti-theft systems to minimize compatibility issues with your Impala’s electronics.
- Configure safety parameters (vehicle in Park, doors locked, hood closed, etc.) and set run times that match local regulations and your needs (commonly 12–20 minutes).
- Test the system in a safe environment to verify it starts reliably and will shut down if any safety condition is violated (e.g., hood is opened, gear moved, or engine overheat conditions).
Important considerations: Aftermarket systems can affect the vehicle’s warranty and may conflict with the factory immobilizer or OnStar features. Ensure the installation is performed by a reputable shop and that you understand any potential warranty implications.
Summary
Remote starting a Chevy Impala generally falls into three paths: using the factory remote start on eligible trims, starting remotely via the OnStar/MyChevrolet app, or installing an aftermarket remote-start system. Availability depends on the model year and trim, and each method has specific safety steps and run-time expectations. Always consult your owner’s manual or dealer for model-specific instructions and ensure compliance with local laws and warranty terms.
