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 begin it without ever removing it from your pocket. The battery in the key fob will eventually die.

Luckily, you can change the battery yourself using a flathead screwdriver and a lithium battery CR2032 (available in most electronics stores or hardware stores). Here's how!

Keyless Entry

Your lexus key fob (via Glamorouslengths) comes with hardware that connects with the sensors in your vehicle. It lets you lock and unlock your doors or trunk, and then start the ignition by pressing a button. This fantastic convenience makes driving with a Lexus more enjoyable than driving the typical vehicle. However, the key fob is going to eventually require an upgrade to its battery in order to function properly.

The good news is that you can extend the life of the battery in your key fob by keeping it at a minimum of three feet away from electrical appliances that create magnetic fields, such as televisions, cell phones, batteries, induction cookers, battery chargers, and table lamps. This is because the closer your key fob is these devices, the greater power it will use.

Another way to make sure your key fob lasts for a long time is to use it only for the functions you require. It is also possible to save your battery by cutting down on the time you use your buttons. Press the LOCK and UNLOCK buttons simultaneously. The electronic indicator for the key will flash four times, which indicates that your key fob is in battery-saver mode. Press any button on the key fob after the lights stop flashing to restore it in working in good working order.

Immobilizer System

When you put your key in the ignition, it sends an ID code to a receiver within the car. The computer will allow the engine to start in the event that the ID code matches the one previously stored in the car. However, if the ID number doesn't match, it triggers an immobilizer which prevents the engine from running.

This technology is effective even if your keys are 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 detect the signal and spoof it to inform the vehicle that the key is present.

Experts are working on more secure methods to thwart this. Certain systems provide WiFi connectivity un-detectable installations, as well as pin code entry via buttons on the dashboard. Thatcham Research has developed a system of grading and approbation for buyers to evaluate products.

If you're concerned about the anti-theft system that is in your vehicle, changing the battery is the simplest thing to do. A quick glance through the owner's manual should assist you in finding the proper replacement. Fuses can also be a source of trouble and you must make sure you check them on a regular basis. Replacement parts are available at the auto parts store if one fails.

Key Blade

Your Lexus key comes with a metal emergency key blade which will open the lock cylinders of your vehicle's doors and ignition. Your key fob has components for communicating with the Smart Access system of your vehicle, and also a button to start your car. While your key fob is designed to last a long time, daily use and exposure to weather elements can cause it to fail sooner than you would expect. To avoid this we recommend that you store your key fob away from your vehicle as much as possible to reduce the frequency of its proximity sensors connecting and draining battery power.

Digital Key

The digital key is one of the coolest features on an Lexus. It allows you to lock or unlock your vehicle and start the motor with just a tap of your mobile device. You can even open the windows or moonroof with this feature. First, you must speak to a technician in order to have this feature activated.

You can also use the digital key to share access with family and friends, particularly if you're planning on leaving your car at home when you travel. To accomplish this, press the lock symbol on your key fob, then tap the lock icon on your phone. Your Lexus will then display an "Unlock" message.

If you're leaving your car for a long time, you can activate battery-saving mode by pressing the unlock and lock buttons on your key fob at the same time. Press the lock button to restart the vehicle.
