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 comes a time when the battery of the key fob will die.

You can replace the battery using a CR2032 Lithium battery (available in a majority of hardware or electronics stores). Learn how to do it here!

Keyless Entry

Your Lexus key fob is fitted with a hardware that communicates with sensors in your car to allow you to lock and unlock doors, open your trunk, and turn on your push-button engine. This remarkable convenience makes driving in a Lexus more enjoyable than driving a traditional vehicle. However, lexus car key replacement is going to eventually require batteries replaced in order 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 least three feet away from electrical appliances that produce a magnetic field, including cellphones, televisions, battery chargers, induction cookers and table lamps. This is because the closer your key fob is these devices, the greater power it uses.

The other way to ensure your key fob will last a long time is to use it only for the functions that you require. You can also reduce battery life by reducing how you hold the buttons. To do this, hold the LOCK button and the UNLOCK button simultaneously. The electronic indicator for the key will flash four times to indicate that your key fob has entered battery-saving mode. Press any button on the key fob after the lights have stopped flashing to restore it in working in good working order.

Immobilizer System

When you put your key in the ignition, it transmits an ID code to a device inside the car. The computer will allow the engine to start if the ID code matches an earlier one stored in the car. If the ID code doesn't match, an immobilizer is triggered that prevents the car from getting started.

This technology isn't 100% secure but it works even when you lose your keys. It is possible to "hack" or alter the radio wave anti-theft system. A thief could use an aerial antenna to detect the signal and spoof it to inform the car that the key is present.

Experts are putting together more secure systems to circumvent this. Some provide WiFi connectivity with undetectable installation as well as pin code entry using buttons on the dashboard. To assist buyers in choosing the most reliable security features, Thatcham Research offers a rating and approval system to make it easier to assess the security features of different 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 find the correct replacement by checking the owner's guide. Fuses can also be a cause, so they should be checked regularly. If one fails, a replacement can be easily purchased from an auto parts store.

Key Blade
