When Your Lexus Smart Key Fails
The Smart Key is an ultra-convenient feature that lets you lock and unlock your 2021 Lexus IS, open the trunk, and start it without ever taking it from your pocket. The battery of the key fob will eventually degrade.
Luckily, you can replace the battery yourself using the flathead screwdriver along with a CR2032 lithium battery (available at most hardware stores or electronics stores). Here's how to do it!
Keyless Entry
Your Lexus key fob is equipped with technology that connects to sensors inside your vehicle to let you lock and unlock your doors and trunk, as well as unlock the trunk and also start the ignition push-button. This is an incredible convenience that makes driving a Lexus an absolute blast than it would be in the traditional car. The key fob may require replacement with an entirely new battery at some point to function effectively.
The good news is that you can prolong the life of the battery in your key fob by making sure it is kept at least three feet away from electrical appliances that produce a magnetic field, including televisions, cell phones, battery chargers, induction cookers and table lamps. The closer your key fob is to these devices, the more power they'll consume.
Another method to ensure your key ring lasts for a long time is by using it only for the functions you need. You can also extend battery life by reducing the long you use the buttons.

Immobilizer System
When you insert the key into the ignition, it sends an identification code to a receiver within the car. The computer will allow the engine to start if the ID code is similar to an earlier one stored in the car. If the ID code doesn't match, an immobilizer will be activated to stop the car from getting started.
This technology isn't foolproof however, it can be effective even in the event you lose your keys. It is possible to "hack" an anti-theft system that makes use of radio waves. A criminal could use an aerial antenna to detect the signal and then spoof it to tell the vehicle that the key is present.
Experts are developing more secure methods to thwart this. Some systems offer WiFi connectivity un-detectable installations, as well as pin code entry via buttons on the dashboard.

Fuses are a different cause and should be checked regularly. If one of them blows, a replacement can be easily located at an auto parts store.
Key Blade
Your Lexus key has an aluminum blade that can be used to open the lock cylinders on the ignition of your vehicle and doors. The key fob also has hardware that connects to your vehicle's Smart Access system and push-button start. Although your key fob is designed to last for a long time, constant use and exposure to weather elements could cause it to fail sooner than you would expect. To help prevent this we recommend that you store your key fob away from your vehicle as far as possible to reduce the frequency of its proximity sensors connecting and using up battery power.
