How to enable Toyota Fortuner key fob battery saving function

The Toyota Fortuner comes with a key fob for convenient entry and ignition. The key fob has a battery-saving function that can help extend the life of the battery. In this article, we will discuss how to enable this function and how it can help prevent theft.

What is relay theft?

Relay theft, also known as keyless entry theft or relay attack, is a type of car theft that targets vehicles with keyless entry systems. This method of theft involves two criminals working together using a relay device. One criminal stands near the vehicle while the other stands near the owner’s home, where the car key is located. The device then picks up the signal from the key fob and relays it to the criminal near the car, who is then able to unlock and start the vehicle without the key.

Relay theft has become a growing concern as car manufacturers have transitioned to keyless entry systems in recent years. Many modern key fobs emit a signal that can be intercepted by relay devices, making it easier for thieves to gain access to vehicles. It is important for car owners to take steps to protect their vehicles from relay theft, such as using steering wheel locks, parking in well-lit areas, and keeping their key fobs in a faraday bag to block the signal.

Using a special device, the very weak radio signal from the key fob, which is normally only sufficient to open the car when in a very close proximity, is transmitted over several hundred feet.

Fortunately, you do not have to buy a faraday bag for the key fob of your Fortuner, as it has a function to disable the keyless entry signals.

How to enable battery saving function

Enabling the battery-saving function on your Toyota Fortuner’s key fob is a simple process that can help extend the life of your key fob battery and prevent theft. To enable the battery-saving function, follow these steps:

  1. Press and hold the lock button on your key fob.
  2. While still holding the lock button, press the unlock button twice.
  3. Release both buttons at the same time.
  4. The LED indicator light on the key fob flashes 4 times to indicate that the function has been activated.
Press the unlock button twice while pressing and holding the lock button.

When the battery-saving function is enabled, the key fob will enter a low-power sleep mode. This helps to conserve the battery life and extend the time between battery replacements. To wake up the key fob from sleep mode, simply press any button on the key fob.

How the battery saving function in Fortuner can prevent theft

Enabling the battery-saving mode on your Toyota Fortuner’s key fob is a great way to extend the life of your key fob battery. However, it’s important to note that while the battery-saving mode is enabled, the smart entry and start system cannot be used. This means that the keyless entry system is disabled, which makes it much more difficult for thieves to steal your car using the relay theft method.

When the smart entry and start system is disabled, the key fob’s signal cannot be intercepted by relay devices. This makes it much harder for thieves to gain access to your vehicle, as they would need to physically obtain the key to unlock and start the car.

By taking steps to protect your vehicle from relay theft, you can help ensure that your Fortuner stays where it belongs – in your possession.
