Remote start is activated by using your car’s built-in remote-start feature or an aftermarket system, usually via the key fob or a smartphone app.
Remote starting allows you to warm up or cool down the cabin before you enter, and many modern vehicles offer this feature as standard or optional equipment. The exact steps vary depending on whether you have factory-installed remote start or an aftermarket installation, as well as your specific make and model. This guide outlines common methods, safety considerations, and troubleshooting tips to help you get started.
Factory-Installed Remote Start
Many newer vehicles include remote start as either a standard feature or an optional upgrade. Below are the most common ways to activate it, depending on how your car is configured.
Using the Key Fob
Before you use the key fob, know that the exact sequence can vary by manufacturer and model—check your owner's manual for the precise method. The following patterns are widely reported across brands:
- Double-press the Lock button within a few seconds to start the engine.
- Press and hold the Lock button for several seconds (often 3–5 seconds) to initiate remote start.
- Some models require a specific sequence like pressing Lock twice quickly, followed by pressing and holding for a moment.
After a successful start, the engine runs for a preset duration (commonly 10–15 minutes) and climate control may precondition the cabin. To stop the engine, use the same fob sequence or press the Start/Stop button if your vehicle supports it.
Using the Smartphone App
If your vehicle supports remote start via a connected app, the steps typically look like this. The exact flow depends on the brand and the app you use.
- Open the vehicle’s official app and sign in if required, with any two-factor authentication enabled.
- Select Remote Start and confirm your action (you may need to verify location or vehicle status).
- The engine starts and runs for the pre-set duration; climate control may engage automatically.
- To stop early or extend the duration (if supported), use the app’s Stop button or adjust settings.
After starting, you’ll typically receive a notification in the app indicating that the system is active and how much time remains. Always ensure doors are closed and the vehicle is in Park before starting remotely.
Aftermarket Remote Start Systems
If your car is equipped with an aftermarket remote start system, the activation method depends on the brand and installation. Here’s what to expect and how to proceed.
Using the System’s Remote or App
Follow brand-specific instructions, but the general process is similar across popular systems:
- Ensure the vehicle is in Park, doors are closed, and the parking brake is engaged.
- Press the remote Start button on the aftermarket remote or use the companion smartphone app to start the engine.
- The engine typically runs for a configurable duration, with climate control preconditioning if supported.
- To end the session, press the Stop command on the remote or in the app, or perform the standard shutdown action per the system’s instructions.
Note that aftermarket systems may require specific programming with the vehicle’s immobilizer and may have different security features. Always follow the installer’s guidance and test in a safe environment before relying on it in daily use.
Professional Installation and Support
For aftermarket setups, professional installation is often recommended to ensure compatibility with your vehicle’s security and electrical systems, maintain warranty coverage, and comply with local regulations.
- Confirm compatibility with your vehicle’s immobilizer, airbags, and electrical system.
- Ensure the installer programs the system to avoid conflicts with factory safety features.
- Ask about operating duration, heat/defrost preconditioning, and how to disable remote start when needed.
Professional installation can tailor the system to your preferences and vehicle, including duration limits and access controls.
Safety and Legal Considerations
Remote start brings convenience, but you should observe safety and legal guidelines to prevent accidents or fines.
- Idling laws: Some jurisdictions limit how long a vehicle may idle, especially in cold weather. Check local rules.
- Occupants and pets: Never leave people or animals inside a running vehicle, particularly in enclosed spaces.
- Security: Keep your key fob secure; never leave the fob inside the vehicle while remotely starting it.
- Transmission and vehicle type: Remote start is typically intended for automatic transmissions; some brands restrict use on manual transmissions.
- Warranty and insurance: Aftermarket systems can affect warranty coverage or insurance terms. Confirm with your dealer or insurer.
Always follow the manufacturer’s instructions and local regulations when using remote start, and consider safety first—heat, cold, and carbon monoxide risks in enclosed spaces are real concerns.
Troubleshooting Common Issues
If remote start isn’t working as expected, try these basic checks before seeking professional help.
- Check the key fob battery and ensure the app is properly authenticated if using a smartphone method.
- Make sure doors are closed, the vehicle is in Park, and the parking brake is engaged.
- Confirm the feature is enabled in the vehicle’s settings or via the installer’s configuration.
- For aftermarket systems, verify that the immobilizer bypass is functioning and that there are no fault codes from the installation.
If issues persist, contact your dealership (for factory systems) or the installer (for aftermarket systems) to diagnose potential wiring, programming, or security interlock problems.
Summary
Remote start is a convenient feature that can be activated via a key fob or a connected app, with differences between factory and aftermarket systems. Always refer to your vehicle’s manual for the exact sequence, follow safety guidelines, and consult a professional if you’re unsure about installation or troubleshooting. With the right setup, you can enjoy a pre-warmed or pre-cooled cabin on demand while staying mindful of local laws and safety considerations.
