When Your Lexus Smart Key Fails
The Smart Key is an ultra-convenient feature that allows you to lock and unlock your 2021 Lexus IS, open the trunk, and begin it without ever taking it from your pocket. However there comes a point when the battery on the key fob dies.
You can replace the battery with the CR2032 lithium battery (available in most electronics or hardware stores). Here's how to do it!
Keyless Entry
Your Lexus key fob comes with hardware that connects with the sensors in your vehicle. This lets you lock and unlock your doors and trunk, as well as open it and then start the ignition by pressing a button. This is an incredible convenience that makes driving with a Lexus so much more fun than it would be in a traditional car. The key fob will eventually require a battery replacement in order to work properly.
The good news is that you can prolong the life of the battery on your key fob by keeping it at a minimum of three feet away from electrical appliances that produce magnetic fields, including televisions, cell phones, battery chargers, induction cookers and table lamps. This is because the closer your key fob is these devices, the more power it uses.
You can also extend the life of your key fob by using it for the functions you need. It is also possible to save your battery by decreasing the amount of time you use your buttons. Press the LOCK and UNLOCK buttons simultaneously. The electronic key indicator will flash four times to signal that your key fob is in battery-saving mode. Press any button on the key fob once the lights have stopped flashing to restore it in good working order.

Immobilizer System
When you insert the key into the ignition, it sends an ID code to a receiver inside the car. If the ID code is identical to one in its memory, the car's computer allows the engine start. If TheKeyLab doesn't match, an immobilizer is activated that stops the car from getting started.
This technology can be used even if your keys are stolen, but it's not foolproof. It is possible to "hack" an anti-theft system using radio waves. A criminal could use an aerial antenna to detect the signal and spoof it into telling the vehicle that the key is present.
To get around this experts are working on safer systems. Certain systems provide WiFi connectivity as well as undetectable installations, and pin code entry through dashboard buttons. Thatcham Research has developed a method of grading and approval to help buyers compare products.
If you are worried about the anti-theft system that is in your vehicle, changing the battery is the easiest task to complete. A quick glance through the owner's manual will help you find the right replacement. Fuses can also be a source of trouble so be sure to examine them regularly. If one blows, an alternative can be purchased from an auto parts store.
Key Blade
Your Lexus key comes with a metal emergency key blade that can open the lock cylinders in the doors of your vehicle and also the ignition. The key fob is equipped with components for communicating with the Smart Access system of your car and push-button starting. While your key fob was made to last for a long time, constant use and exposure to weather elements can cause it's to fail earlier than you think. To avoid this it is recommended to keep your key fob in a safe place away from your vehicle as much as possible to reduce its proximity sensors from constantly connecting and consuming battery power.

Digital Key
One of the coolest features of the Lexus key is its digital key, which allows you to lock and unlock your vehicle and even start your engine with one touch on your smartphone. You can also roll down the windows and open the roof with this feature. You must first speak to the technician to have this feature activated.
You can also share the digital key with your family or friends, particularly when your car is kept at home during your trip. To do this, press and hold the lock symbol on your key fob while tapping the lock icon on your phone. Your Lexus will then display an "Unlock" message.
Pressing the lock and unlock buttons on your key fob at the same time will enable the battery-saving mode when you leave your vehicle. Then, press the lock button again to reactivate your vehicle. You can also extend the life of the battery in your key fob by keeping it out of the three feet of electrical devices that produce magnetic fields. This includes TVs and laptops as well as batteries, cell phones and even mobile phones.
