When Your Lexus Smart Key Fails
Smart Key is a convenient feature that allows you lock and unlock your Lexus IS 2021, open the trunk and start it without having to remove it from your pocket. The battery of the key fob will eventually die.
Luckily, you can change the battery yourself with just an flathead screwdriver and CR2032 lithium battery (available at a majority of electronics stores or hardware stores). Here's how to do it!
Keyless Entry
Your Lexus key fob is armed with a chip that connects to sensors in your vehicle to lock and unlock doors as well as open your trunk and then turn on the push-button engine. This is an incredible convenience that makes driving a Lexus significantly more enjoyable than it would be in an ordinary car. The key fob is going to eventually require a battery replacement in order to perform as it should.
The good news is that you can extend the life of the battery in your key fob by keeping it at least three feet away from electrical appliances that create magnetic fields, like cellphones, televisions, batteries, induction cookers, battery chargers, and table lamps. This is because the closer your key fob is to these devices, the greater power it will use.
Another method to ensure that your key fob lasts for a long time is by using it only for the functions you require. You can also reduce battery life by reducing the you use the buttons. Hold the LOCK and UNLOCK buttons at the same time. The electronic key indicator will flash four times, indicating that your key fob is in battery saver mode. When the lights cease to flash you can push any button on your key fob to make it work again.

Immobilizer System
When you insert the key into ignition, it transmits an identification code to a receiver in the car. If the ID code matches that in its memory, the car's computers allow the engine start. If the ID code does not match, an immobilizer will be triggered that prevents the car from beginning.
This technology can be used even if your keys get stolen but it's not foolproof. It is possible to "hack" an anti-theft system using radio waves. lexus keys could use an aerial antenna to pick up the signal and spoof it to inform the car that the key is present.
Experts are putting together more secure systems to thwart this. Some systems offer WiFi connectivity as well as undetectable installations, and pin code entry using dashboard buttons. To help customers choose the most reliable security features, Thatcham Research offers a assessment and approval process to help you assess the security features of different products.
If you're concerned regarding the security system in your car the easiest thing to do is replace the battery, if it's old. You can determine the correct replacement by looking up the owner's guide. Fuses can also be a source of trouble so be sure to check them regularly. A replacement can be found at the auto parts store in case one fails.
Key Blade
Your Lexus key comes with a blade made of metal that can be used to open the lock cylinders on your vehicle's ignition and doors. Your key fob has hardware for communication with the Smart Access system of your vehicle and a button for starting. The key fob might be made to last an extended period of time, but regular use and exposure of weather elements can make your key fail earlier than you anticipated. To help prevent this we suggest that you keep your key fob in a safe place away from your vehicle as far as possible to reduce its proximity sensors from constantly connecting and draining battery power.

You can also utilize the digital key to share access with family and friends, especially when you plan to leave your car at home as you travel. To do this, press the lock symbol located on the key fob and tap the lock icon on the phone. Your Lexus will then display an "Unlock" message.
