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 then start it without ever taking it from your pocket. However there will come a point when the battery on the key fob expires.
Luckily, you can replace the battery yourself using a flathead screwdriver as well as a lithium battery of the CR2032 type (available at a majority of electronics stores or hardware stores). Learn how to do it here!
Keyless Entry
Your Lexus key fob comes with a device that communicates with sensors in your car to allow you to lock and unlock doors as well as open your trunk and then turn on the engine. This is an incredible convenience that makes driving with a Lexus far more enjoyable than it would be in an ordinary car. The key fob may need to be replaced with an additional battery at some point in order to function properly.
The good news is that you can extend the life of the battery on your key fob by keeping it at least 3 feet away from electrical appliances that create magnetic fields, such as TVs, cell phones and battery chargers, induction cookers and table lamps. This is because the closer your key fob is to these devices, the more power it will use.
You can also prolong the life of your key fob by only using it only for the functions you require. You can also save your battery by decreasing the amount of time you use your buttons. To do this, hold the LOCK button and the UNLOCK button at the same time. The electronic indicator for the key will flash four times, indicating that your key fob is in battery-saver mode. When the lights stop flashing you can press any button on your key fob to get it working again.

Immobilizer System
When you put the key in the ignition, it sends an ID code to a receiver within the car. If the ID code matches that in its memory, then the car's computer will let the engine start. If the ID code does not match, it activates an immobilizer, which stops the engine from starting.
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 that uses radio waves. The thief could employ an aerial antenna to pick up the signal and then spoof it to inform the car that the key is in.
