The Lexus RX 350 is a popular luxury SUV known for its reliability and features. One sought-after feature, especially in climates with extreme temperatures, is remote start. Many owners appreciate the convenience of starting their RX 350 remotely, allowing the engine to warm up or cool down the cabin before they even step inside. If you’re wondering how to utilize the remote start feature on your Lexus RX 350 using your key fob, or if you’re encountering issues with it, this guide is for you.
Understanding Lexus RX 350 Key Fob Remote Start
The most straightforward way to remote start your Lexus RX 350 is using the key fob. Here’s how it generally works:
- Press the “Lock” button: Press and release the “Lock” button on your Lexus key fob.
- Press the “Lock” button again: Immediately press and release the “Lock” button a second time.
- Press and hold the “Lock” button: Press and hold the “Lock” button for about three seconds.
After performing these steps correctly, your Lexus RX 350 engine should start. The vehicle’s parking lights will typically flash to confirm the remote start has been initiated. The engine will run for a predetermined time, usually around 10 minutes, and then shut off automatically if no further action is taken.
It’s important to note that the exact sequence and timing might slightly vary depending on the specific model year and options package of your Lexus RX 350. Always refer to your owner’s manual for the most accurate instructions for your vehicle.
Is Remote Start Free on Your Lexus RX 350?
This is where some confusion and frustration can arise, as seen in online forums. While the physical key fob remote start function itself is generally built into the vehicle’s system, some connected services related to remote start might involve subscriptions.
Lexus Enform Remote, a suite of connected services, offers enhanced remote features via a smartphone app, including remote start, door lock/unlock, vehicle health reports, and more. Typically, Lexus provides a trial period for Enform Remote services on new vehicles. This trial period is often complimentary for a limited time, such as the first year of ownership.
After the complimentary period expires, continued access to Lexus Enform Remote services, which may include key fob integration for certain features or enhanced app-based remote start functionalities, usually requires a paid subscription.
Therefore, while the basic key fob remote start functionality might seem like it should be “free” as it’s a feature of the key fob itself, the services that enhance or enable certain aspects of remote start (especially app-based features) can be subscription-based.
It’s crucial to check your Lexus vehicle’s documentation and the Lexus Enform website for specific details regarding complimentary periods and subscription requirements for remote start and related services. Your Lexus dealership can also provide clear information about what’s included and what might require a subscription.
Troubleshooting Remote Start Issues
If your Lexus RX 350 remote start isn’t working with the key fob, here are a few things to check:
- Battery Voltage: Ensure your vehicle’s battery is adequately charged. A low battery can sometimes prevent remote start from functioning.
- Key Fob Battery: A weak battery in your key fob can also cause issues. Try replacing the key fob battery.
- Obstructions and Range: Remote start has a limited range. Make sure you are within a reasonable distance of your vehicle and that there are no significant obstructions between you and the RX 350.
- Hood and Door Sensors: Remote start systems often have safety interlocks. Ensure that your hood, doors, and tailgate are fully closed. A faulty sensor might prevent remote start if the system thinks a door is ajar.
- System Errors: Check your driver information display for any error messages related to remote start or the vehicle system.
- Subscription Status (if applicable): If you are relying on Lexus Enform Remote for remote start functionality, verify your subscription is active.
If you’ve checked these basic troubleshooting steps and your remote start still isn’t working, it’s recommended to consult your Lexus dealership. They can diagnose any potential technical issues with the remote start system and provide appropriate repairs or guidance.
Exploring Aftermarket Remote Start Options
If you find the subscription costs for Lexus Enform Remote not to your liking, or if your Lexus RX 350 model doesn’t have factory remote start, the aftermarket offers solutions. Numerous reputable aftermarket remote start systems are available for the Lexus RX 350.
These systems can offer various features, including:
- Extended Range: Some aftermarket systems boast significantly longer range than factory key fobs.
- Smartphone Control: Many aftermarket systems also include smartphone app control, sometimes without recurring subscription fees (though some advanced features might have optional subscriptions).
- Two-Way Communication: Two-way systems confirm successful remote start on your key fob or smartphone, providing added peace of mind.
When considering aftermarket remote start, choose reputable brands and professional installation to ensure proper integration with your Lexus RX 350’s electrical system and to maintain your vehicle’s warranty.
Conclusion
Remote start is a valuable feature for Lexus RX 350 owners, offering enhanced comfort and convenience. Understanding how to use the key fob remote start, being aware of potential subscription-based services, and knowing basic troubleshooting steps can help you maximize your enjoyment of this feature. If you encounter persistent issues or are interested in exploring alternative remote start options, your Lexus dealer and reputable aftermarket installers are valuable resources.
