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 begin it without ever removing it from your pocket. However, there comes a time when the key fob battery expires.

You can, fortunately, replace the battery yourself with just an flathead screwdriver and lithium battery of the CR2032 type (available in most electronic stores or hardware stores). Here's how!

Keyless Entry

Your Lexus key fob is armed with a device that communicates with sensors in your vehicle to unlock and lock doors, open your trunk, and turn on the push-button engine. This is a wonderful convenience that makes driving a Lexus so much more fun than it would be with an ordinary car. The key fob is going to eventually require an upgrade to its battery in order to work properly.

You can prolong the life of your key fob by keeping it far from magnetic devices like TVs, mobile phones, battery chargers as well as induction cooktops and table lamps. The closer your keyfob is to these devices the more power they'll consume.

Another way to ensure that your key fob lasts a long time is to use it only for the functions that you need. You can also prolong battery life by reducing the you use the buttons. Hold 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 has entered battery-saving mode. When the lights stop flashing you can push any button on your key fob to start it working again.

Immobilizer System

When you insert your key into the ignition, it sends an ID code to a device inside the car. If the ID code matches with one in its memory, the car's computers allow the engine start. But if the ID code does not match, it triggers an immobilizer that stops the engine from running.

This technology is effective even if your keys are stolen but it's not foolproof. It is possible to "hack" or alter, an anti-theft radio wave system. A thief can use an aerial antenna, and then spoof the signal to tell the car the key is in the ignition.

To overcome this experts are developing more secure systems. Some of them offer WiFi connectivity as well as undetectable installation, and pin code entry using dashboard buttons. To help customers choose the most secure security features, Thatcham Research offers a rating and approval system to help you compare the various products.

If you're concerned about the security system installed in your car, replacing batteries is the simplest thing to do. You can determine the correct replacement by checking the owner's guide. Fuses are also a concern and you must check them regularly. A replacement can be found at the auto parts store in case one blows.

Key Blade

Your Lexus key has an iron blade that can be used to unlock the lock cylinders on your vehicle's ignition and doors. The key fob also houses hardware that connects to your car's Smart Access system and push-button start. Your key fob may be designed to last for an extended time, but the constant use and exposure to elements of the weather can make your key fail earlier than you anticipated. To avoid this, keep your keyfob as far away from your car as is possible. This will reduce the battery consumption caused by proximity sensors.

You can also share your digital key with your family or friends, particularly when your car will be left at home on your trip. To do this, hold and press the lock symbol on your key fob while tapping the lock icon on your phone. Your lexus Replacement Keys will then display an "Unlock" message.

Pressing the lock and unlock buttons on your key fob at the same time will activate the battery saving mode in the event that you are leaving your car.
