How to remote start a Lexus RC 350?

Remote starting an RC 350 is possible using either the factory key fob or the Lexus app, depending on your model year and options. This guide covers both methods, plus practical notes to use them safely and effectively.

Overview of remote-start options

The Lexus RC 350 can be started remotely through the traditional key fob or via the Lexus Remote Connect smartphone app. Availability and exact steps can vary by year and package, so consult your owner's manual or dealer if you’re unsure which method your car supports.

Key fob remote start

The following steps describe starting from outside the vehicle using the key fob. If your model year or settings differ, refer to the owner's manual for exact instructions.

• Ensure all doors are closed, windows are up, and the vehicle is locked.


• From outside the RC 350, press the Lock button on the key fob, then immediately press and hold the Lock button again for about 3 seconds until the engine starts.


• The engine will run for a fixed period (commonly around 10 minutes) unless you cancel it earlier. You can cancel by pressing the Lock button again or by unlocking the doors with the fob.


• To drive away after a remote start, unlock the doors, enter the cabin with the key fob, press the brake pedal, and press the Start/Stop button to start normal operation. The car must be in Park to start driving if required by your model.

Note: If the engine does not start, the feature may be disabled or not available on your exact configuration. The fob also needs to be within range for the remote-start command to work.

Lexus app remote start (Remote Connect)

For models equipped with Lexus Remote Connect, you can start the RC 350 from a compatible smartphone. This method requires a compatible model year, an active Remote Connect subscription, and a connected vehicle.

• Open the Lexus app on your smartphone and sign in with your Lexus account.


• Select your RC 350 from the list of devices connected to your account.


• Tap Start Engine (Remote Start) and confirm if prompted. The app will trigger the vehicle to crank and run for the preset duration.


• To stop the engine earlier, use the Stop Engine option in the app. To drive away, you’ll typically need to be inside the vehicle with the key fob, then press the brake and Start/Stop button as you normally would.

Tip: The app-based method depends on cellular connectivity and the vehicle’s internet connection. Availability and duration may vary by market and subscription terms.

Safety considerations and limitations

Remote starting is convenient but should be used responsibly. Do not start the engine in enclosed spaces (garages, carports, or indoors) where exhaust buildup could pose a risk. Ensure the vehicle is in a safe, well-ventilated area and that doors are locked or secure as appropriate before leaving it unattended. Availability and behavior of remote start can be influenced by local laws, model year, and optional packages.

Frequently asked nuances

Here are common nuances you might encounter with the RC 350’s remote-start features:

• Model-year differences: Some older RC 350 trims may not support remote start via the fob or app without specific packages. Check your documentation or ask a dealer.


• Countdown and duration: Remote-start sessions typically run for a fixed window (often around 10 minutes) and then shut off automatically if not canceled.


• Interior readiness: Some setups require a valid key fob to be present in or near the vehicle before you can drive away after a remote start.


• App prerequisites: The smartphone method requires a data connection, an active subscription, and a linked vehicle profile in the Lexus app.

If you experience persistent issues with remote start, contact your Lexus dealer to verify feature availability, subscription status (for Remote Connect), and any vehicle settings that might disable remote start.

Summary

Remote starting an RC 350 can be done via the key fob or through the Lexus app, with each method having specific prerequisites and steps. The fob method is typically quick and works from outside the vehicle, while the app method offers smartphone-based control but requires an active Remote Connect service. Always use remote start in safe, open environments and follow your vehicle’s guidelines to ensure a trouble-free experience.
