Lexus Key Fob Tricks

Are you aware that your Lexus key fob holds more secrets than just locking and unlocking your car doors? These small devices come equipped with hidden features that can greatly enhance your driving experience.

From remote start capabilities to window control, there are numerous tricks you can perform with your Lexus key fob.

In this comprehensive guide, we will explore these mind-blowing features and provide step-by-step instructions on how to utilize them effectively.

How to Use the Hidden Key in Your Lexus Key Fob

Did you know that your Lexus key fob contains a secret mechanical key inside? This hidden key can be incredibly useful in situations where your key fob battery dies and you need to access your car. To locate the hidden key, look for a small button on the key fob that releases it.

The placement of this button may vary depending on the Lexus model year. For newer smart key fobs, the button is typically located on the top left side.

Press the button and pull down from the keychain to remove the mechanical key.

Once you have the mechanical key in hand, go to the driver’s side door and pull the handle open. This will reveal a small keyhole.

Insert and turn the mechanical key to unlock your Lexus. It’s important to note that not all Lexus models have this hidden key feature, so be sure to check your specific model’s manual to confirm its availability.

5 Amazing Lexus Key Fob Tricks

Your Lexus key fob is capable of much more than just basic functions. With a few simple steps, you can unlock these amazing features and take your driving experience to the next level.

Let’s explore five of the most impressive tricks you can perform with your Lexus key fob.

Remote Start

One of the most convenient features of the Lexus key fob is the ability to start your vehicle remotely. This is especially useful during extreme weather conditions, as it allows you to warm up or cool down your car before stepping inside. To activate the remote start function, follow these steps:

  1. Press the lock symbol once to lock the vehicle.
  2. Press the lock button three times, holding it for three seconds on the third press.
  3. After several flashes of the hazard lights, the engine will start within 10 seconds.
  4. Your Lexus will run for 10 minutes unless any door is opened, the brakes are pressed, or the engine is remotely turned off.

Remote start is a convenient feature that adds comfort and convenience to your daily routine. It ensures that your vehicle is at an optimal temperature before you even step inside.

Open Your Windows from Outside the Car

Imagine being able to roll down your windows or open your sunroof from outside the car using just your key fob.

With certain Lexus models, this is indeed possible. However, it’s important to note that this feature may not be activated by default and may require a Lexus technician to enable it for you.

If you’re interested in this functionality, reach out to your nearest Lexus dealership or authorized service center for assistance.

Seat Memory

Do you share your Lexus with multiple drivers? If so, the seat memory feature on your key fob can be a game-changer.

This feature allows you to save up to three different seat positions for different drivers. Here’s how you can set it up:

  1. Adjust your seat to your preferred position.
  2. Press and hold the “set” button on the driver’s door panel until you hear a beep.
  3. Press one of the numbered buttons (1, 2, or 3) on the door panel until you hear another beep.
  4. To pair this setting to your Lexus key fob, simultaneously press and hold the “set” button and the unlock button on your key fob.
  5. You have now paired one of the seat positions to your Lexus key fob.

Repeat this process for other seat positions and key fobs if needed. With seat memory, your Lexus will automatically adjust the seat to the desired position when you use your key fob to unlock the car.

Activate Battery-saving Mode

If you won’t be using your Lexus for an extended period, you can put your key fob in battery-saving mode to prevent unnecessary power consumption. Activating this mode is simple:

  1. Press and hold both the lock and unlock buttons on your key fob for five seconds.
  2. Wait for the red light to flash twice, indicating that the wireless function of your key fob has been deactivated.
  3. To reactivate the key fob, simply press any button.

By utilizing battery-saving mode, you can prolong the battery life of your key fob and ensure it’s ready for use when you need it.

Change the Default Setting for Unlocking the Doors

By default, pressing the unlock button on your key fob unlocks all the doors of your Lexus. However, you can customize this setting to align with your preferences. Here’s how:

  1. Press and hold both the lock and unlock buttons on your key fob for five seconds.
  2. Listen for a beep, indicating that you’ve entered customization mode.
  3. Press the lock button once to cycle through the options:
    • One beep: Only the driver’s door unlocks.
    • Two beeps: All doors unlock.
    • Three beeps: The driver’s door unlocks first, followed by the other doors upon a second press.

Choose the option that suits your needs and preferences.

How to Start Your Lexus with a Dead Key Fob Battery

Even if your key fob battery is dead, you can still start your Lexus with ease. Follow these steps to get your vehicle up and running:

  1. Place the Lexus emblem on the back of the key fob against the start/stop push button in your car.
  2. Put your foot on the brake pedal.
  3. Press the start button.

Your Lexus should start normally, even with a dead key fob battery. However, it’s advisable to replace the battery as soon as possible to ensure uninterrupted functionality.

How to Save the Battery Life of Your Lexus Key Fob

To maximize the battery life of your Lexus key fob, consider implementing the following tips:

  1. Replace the batteries regularly: The more you use your key fob, the quicker the batteries will drain. It’s recommended to replace them every 6-8 months or as needed.
  2. Keep your key fob away from electronic devices: Avoid storing or placing your key fob near electronic devices that may interfere with its functionality or drain the battery.
  3. Use battery-saving mode: When you know you won’t be using your key fob for an extended period, activate the battery-saving mode to conserve power.
  4. Clean the key fob contacts: Over time, dirt and debris can accumulate on the key fob contacts, affecting its performance. Regularly clean the contacts with a soft cloth or cotton swab dipped in rubbing alcohol.

By following these simple steps, you can extend the battery life of your Lexus key fob and ensure reliable operation when you need it most.
