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. However there will come a point when the battery on the key fob will die.

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

Keyless Entry

Your Lexus key fob is equipped with hardware that connects with the sensors in your vehicle to let you lock and unlock your doors, open the trunk, and also start the ignition push-button. This is an incredible convenience that makes driving a lexus remote key significantly more enjoyable than driving the traditional car. However, the key fob will eventually require an upgrade in battery to function properly.

The good news is that you can prolong the life of the battery on your key fob by keeping it at least three feet away from electrical appliances that create a magnetic field, including TVs, cell phones, battery chargers, induction cookers, and table lamps. The closer your key fob is to these devices, the more power they'll use.

Another method to make sure your key fob lasts a long time is by using it only for the functions that you need. You can also save your battery by reducing the time you press your buttons. To do this, hold the LOCK button and the UNLOCK button at the same time. The electronic key indicator will flash four times to show that your key fob is in battery-saving mode. Press any button on the key fob when the lights stop flashing to get it back in good working order.

Immobilizer System

When you insert the key into ignition, it sends an ID code to a receiver in the car. If the ID code matches with one in its memory, then the car's computer allows the engine start. 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 if you lose your keys. It is possible to "hack" an anti-theft system that makes use of radio waves. A criminal can employ an aerial antenna and spoof the signal to inform the car the key is in the ignition.

Experts are working on more secure systems to circumvent this. Certain systems provide WiFi connectivity un-detectable installations, as well as pin code entry via dashboard buttons. To help buyers select the most secure security features, Thatcham Research offers a rating and approval system to make it easier to compare products.

If you're concerned about the security of your vehicle's anti-theft system the easiest thing to do is to replace the battery, if old. You can determine the correct replacement by checking the owner's guide. Fuses can also be a problem and you must check them regularly. The replacement is available at the auto parts store if one fails.

Key Blade

Your Lexus key comes with a metal emergency key blade that who can cut a Lexus key open the lock cylinders of your vehicle's doors and ignition. Your key fob comes with hardware for communication with the Smart Access system of your vehicle, and also a button to start your car. While your key fob was designed to last a long time, constant use and exposure to elements of the weather can cause it to fail sooner than you would expect. To prevent this from happening we suggest that you keep your key fob in a safe place away from your vehicle as far as you can to prevent the frequency of its proximity sensors connecting and consuming battery power.

You can also share the digital key with family or friends, especially in the event that your car will be in the garage during your travels. To do this, press the lock symbol located on the key fob and tap the lock icon on your phone. Your Lexus will then display an "Unlock" message.

Pressing the lock and unlock buttons on your key fob simultaneously will activate the battery saving mode if you are leaving your car. Press the lock button to reactivate the vehicle.
