Keyless Entry

Your Lexus key fob comes with a chip that connects to sensors in your vehicle to unlock and lock doors as well as open your trunk and then turn on the engine. This is an amazing convenience that makes driving with a Lexus so much more fun than it would be in conventional cars. The key fob may need to be replaced with an additional battery at some point in order to function correctly.

You can prolong the life of your battery keyfob by keeping it away from magnetic appliances such as TVs mobile phones, televisions, battery chargers as well as induction cooktops and table lamps. This is because the closer your key fob is these devices, the more power it will use.

Another way to ensure that your key fob will last a long time is by using it only for the functions you need. You can also save your battery by reducing the time you press your buttons. Hold the LOCK and UNLOCK buttons at the same time. The electronic key indicator will flash four times, indicating that your key fob has entered 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 put your key in the ignition, it sends an ID code to the receiver 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 does not match, an immobilizer will be triggered that prevents the car from starting.

This technology isn't foolproof but it works even in the event you lose your keys. It is possible to "hack" an anti-theft system that makes use of radio waves. A thief could use an aerial antenna to pick up the signal and spoof it into telling the car that the key is present.

Experts are working on more secure methods to avoid this. Some systems offer WiFi connectivity as well as undetectable installations, and pin code entry via buttons on the dashboard. To assist buyers in choosing the most reliable security features, Thatcham Research offers a assessment and approval process to help you assess the security features of different products.

Your key fob has components that communicate with the Smart Access system of your car and push-button starting. Your key fob might be designed to last for a long time but daily use and exposure to elements of the weather can cause your key to malfunction sooner than anticipated.
