Lexus vehicles are renowned for their luxury, performance, and cutting-edge technology, offering drivers a premium experience. One of the convenient features that Lexus provides in many of its models is remote start. This allows you to start your car from a distance, letting you pre-heat or pre-cool the cabin for optimal comfort before you even step inside. For many Lexus owners, the key fob is the primary tool for utilizing this feature. This guide will provide you with a detailed, step-by-step explanation on how to start your Lexus using your key fob, ensuring you can take full advantage of this handy technology.
Before attempting to remotely start your Lexus with the key fob, it’s important to ensure your vehicle is in the correct state and meets certain conditions. These are in place for safety and to ensure the remote start system functions correctly. Your Lexus must meet the following criteria:
- Parked: The vehicle must be completely parked and not in motion.
- All Doors Closed and Locked: All doors, including the trunk and hood, must be fully closed and securely locked. The system is designed to prevent remote start if any entry point is ajar.
- Moonroof Closed: If your Lexus is equipped with a moonroof, it should be fully closed.
- Sufficient Fuel: Ensure your Lexus has at least a quarter of a tank of fuel. The remote start system may be disabled if fuel levels are critically low.
Once you have confirmed that your Lexus meets these prerequisites, you are ready to initiate remote start using your key fob. Follow these simple steps:
-
Press the Lock Button: Locate the lock button on your Lexus key fob. Press it once firmly. You should see the vehicle’s lights flash, confirming the lock command has been received.
-
Press the Lock Button Again (Within One Second): Immediately after the first press, press the lock button a second time. This double press is a deliberate action to prevent accidental remote starts.
-
Press and Hold the Lock Button: After the second press, press and hold the lock button. Keep it pressed for a few seconds until you observe the vehicle’s lights flash again. This time, the flashing lights indicate that the remote start sequence has been initiated.

After successfully completing these steps, you should hear your Lexus engine start. The hazard lights will typically flash for approximately 20 seconds to indicate that the engine is running remotely. The engine will then continue to run for a pre-set duration, usually around 10 minutes. This allows sufficient time to warm up your car in cold weather or cool it down on a hot day before you get in. After the 10-minute period, the engine will automatically shut off to conserve fuel and for safety.
While the key fob remote start is generally reliable, there might be instances where it doesn’t work as expected. Here are a few common troubleshooting tips:
- Check Key Fob Battery: A weak battery in your key fob can significantly reduce the signal strength and range. Try replacing the battery with a fresh one to ensure optimal performance.
- Obstructions and Range: Walls, buildings, and other obstructions can interfere with the key fob signal. Ensure you are within a reasonable range of your vehicle and have a clear line of sight if possible.
- Vehicle System Issues: In rare cases, there might be an issue with the vehicle’s remote start system itself. If you consistently experience problems, it’s advisable to consult your Lexus dealership for a diagnostic check.
- Ensure Prerequisites are Met: Double-check that all doors, trunk, hood, and moonroof are securely closed and that you have sufficient fuel. The system will not engage if these conditions are not met.
To maximize the effectiveness and lifespan of your Lexus key fob remote start, consider these tips for optimal use:
- Avoid Excessive Use in Enclosed Spaces: While convenient, avoid frequently using remote start in enclosed garages or poorly ventilated areas due to the risk of carbon monoxide buildup.
- Regular Key Fob Maintenance: Protect your key fob from extreme temperatures, moisture, and physical damage to ensure its longevity and reliable operation.
- Understand System Limitations: Be aware of the 10-minute runtime limitation and plan accordingly. If you need to extend the engine running time, you may be able to initiate remote start again (refer to your owner’s manual for specific instructions).
The key fob remote start feature is a valuable asset in your Lexus, offering enhanced comfort and convenience. By understanding the simple steps and conditions required, you can easily start your Lexus remotely and enjoy a more pleasant driving experience from the moment you get behind the wheel.
