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 for the key fob dies.
You can replace the battery with a CR2032 Lithium battery (available in a majority of hardware or electronics stores). Find out how to do it here!
Keyless Entry
Your Lexus key fob has technology that connects to sensors in your vehicle. This lets you lock and unlock your doors or trunk, and start the push-button ignition. This is an incredible convenience that makes driving in a Lexus far more enjoyable than it would be in conventional cars. However, the key fob will eventually need an upgrade in battery to perform as it should.
You can extend the battery life of your keyfob by keeping it out from appliances that are magnetic, such as TVs mobile phones, TVs chargers as well as induction cooktops and table lamps. The closer your keyfob is to these appliances, the more power they'll use.
The other way to ensure that your key ring lasts for a long time is to use it only for the functions that you need. You can also save battery life by reducing the long you use the buttons. Hold the LOCK and UNLOCK buttons simultaneously. The electronic indicator for the key will flash four times to show that your key fob has entered the battery-saving mode. Once the lights stop flashing you can push any button on your key fob to get it working again.

Immobilizer System
When you put the key in the ignition, it sends an identification code to the receiver in the car. If the ID code matches one in its memory, then the car's computer will let the engine start. However, if the ID code does not match, it activates an immobilizer which prevents the engine from starting.
This technology works even if your keys are stolen however, it's not foolproof. In fact, it's possible to "hack" an anti-theft system using radio waves. A criminal can employ an aerial antenna to spoof the signal to inform the car the key is in the ignition.
To avoid this, experts are working on safer systems. Some systems offer WiFi connectivity, undetectable installations and pin code entry through dashboard buttons. To help customers choose the most reliable security features, Thatcham Research offers a rating and approval system to help you compare products.
If you're worried about the anti-theft feature of your car the best thing you can do is to replace the battery, if old. You can locate the right replacement by consulting the owner's manual. Fuses can also be a source of trouble, so you should check them regularly. If one blows up, an alternative can be located at an auto parts store.
Key Blade
Your Lexus key is equipped with a steel emergency key blade that will open the lock cylinders of your vehicle's doors and ignition. thekeylab.co.uk has hardware that communicates with your car's Smart Access system and push-button start. While your key fob is designed to last for a lengthy duration, everyday use and exposure to elements of the weather can cause it to fail sooner than you might expect. To avoid this we recommend that you store your key fob in a safe place away from your vehicle as far as possible to reduce its proximity sensors from continuously connecting and draining battery power.
