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 then start it without ever removing it from your pocket. However there will come a point when the battery on the key fob is dead.
Luckily, you can change the battery on your own with an flathead screwdriver and lithium battery of the CR2032 type (available in most hardware stores or electronics stores). Here's how!
Keyless Entry
Your Lexus key fob is fitted with a device that communicates with sensors in your vehicle to unlock and lock doors unlock your trunk and then turn on the push-button engine. This is a wonderful convenience that makes driving with a Lexus significantly more enjoyable than it would be with conventional cars. However, the key fob will eventually need an upgrade in battery to perform as it should.
You can prolong the battery life of your key fob by keeping it away from magnetic appliances like TVs mobile phones, televisions, battery chargers as well as induction cooktops and table lamps. The closer your key fob is to these devices the more power they will use.
Another method to ensure that your key fob will last a long time is to use it only for the functions that you require. You can also reduce the use of your battery by cutting down on the time you use your buttons. Hold the LOCK and UNLOCK buttons at the same time. The electronic key indicator will flash four times, signalling that your key fob is in battery-saver mode. Press any button on the key fob until the lights have stopped flashing to get it back in working order.

Immobilizer System
When you put your key in the ignition, it sends an ID code to a receiver inside the car. If the ID code matches that in its memory, the car's computer allows the engine start. But if the ID code does not match, it activates an immobilizer which prevents the engine from starting.
The technology isn't completely foolproof but it works even when you lose your keys. In fact, it's possible to "hack" an anti-theft device that relies on 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.
Experts are putting together more secure methods to thwart this. Some offer WiFi connectivity, undetectable installation and pin code entry using buttons on the dashboard. To help buyers select the most secure security features, Thatcham Research offers a grade and approval system to help you evaluate products.
If you're concerned about the anti-theft system in your car, replacing the battery is the most straightforward step to take. You can find the correct replacement by consulting the owner's manual. Fuses are another potential culprit therefore they should be checked on a regular basis. If one blows, an alternative can be purchased from an auto parts store.
Key Blade
Your Lexus key has an aluminum blade that can be used to open the lock cylinders on your vehicle's ignition and doors. Your key fob comes with hardware for communication with the Smart Access system of your car, as well as a push-button for starting. While your key fob has been designed to last for a lengthy duration, regular use and exposure to elements of the weather can cause it to fail earlier than you think. To avoid this we recommend that you store your key fob in a safe place away from your vehicle as far as you can, to stop its proximity sensors from continuously connecting and consuming battery power.
