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 removing it from your pocket. However there will come a point when the battery on the key fob will die.

You can replace the battery with the CR2032 Lithium batteries (available in most electronic or hardware stores). Here's how!

Keyless Entry

Your Lexus key fob is armed with a device that communicates with sensors in your car to lock and unlock doors as well as open your trunk and then turn on the push-button engine. This remarkable convenience makes driving with a Lexus more enjoyable than driving any other vehicle. However, the key fob will eventually need an upgrade in battery to perform as it should.

The good news is that you can prolong the life of your key fob's battery by keeping it at a minimum of three feet away from electrical appliances that generate magnetic fields, like cellphones, televisions, battery chargers, induction cookers and table lamps. The closer your key fob is to these devices, the more power they'll use.

You can also extend the life of your key fob by only using it for the functions that you require. You can also save battery life by reducing the long you use the buttons. Press the LOCK and UNLOCK buttons at the same time. The electronic indicator for the key will flash four times to indicate that your key fob is operating in battery-saver mode. Press any button on the key fob when the lights have stopped flashing to get it back in working condition.

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 if the ID code is similar to the previous one that is stored in the car. If the ID code doesn't match, an immobilizer will be activated, which stops the car from beginning.

This technology is effective even if your keys get stolen, but it's not foolproof. In fact, it's 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 tell the car that the key is present.

To overcome this, experts are developing more secure systems. Some systems include WiFi connectivity as well as undetectable installations, and pin code entry via dashboard buttons. Thatcham Research has developed a system of grading and approbation to allow buyers to compare the various products.

If you're worried regarding the security system in your car the easiest thing to do is to replace the battery if it's old. You can determine the correct replacement by referring to the owner's guide. Fuses can also be a source of trouble and you must check them regularly. The replacement is available at the auto parts store in case one blows.

Key Blade

Your Lexus key comes with a metal blade that can be used to unlock the lock cylinders on your vehicle's ignition and doors. Your key fob has components for communicating with the Smart Access system of your car and push-button starting. Although your key fob is designed to last a long duration, everyday use and exposure to weather elements could cause it to fail sooner than you'd expect. To prevent this from happening we suggest that you keep your key fob in a safe place away from your vehicle as much as you can, to stop its proximity sensors from continuously connecting and consuming battery power.
