Keyless Entry

This is a fantastic convenience that makes driving in a Lexus an absolute blast than it would be with an ordinary car. However, the key fob will eventually require an upgrade to its battery in order to perform as it should.

The good news is that you can prolong the life of the battery in your key fob by keeping it at least three feet away from electrical appliances that generate magnetic fields, like TVs, cell phones and batteries, induction cookers, battery chargers, and table lamps. This is because the closer your key fob is to these devices, the more power it draws from.

Another way to ensure your key fob lasts a long time is by using it only for the functions that you require. You can also extend battery life by reducing the long you hold the buttons. Hold the LOCK and UNLOCK buttons 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 have stopped flashing to bring it back in good working condition.

Immobilizer System

When you put your key in the ignition, it transmits an ID code to a receiver inside the car. If the ID code is identical to one in its memory, then the car's computer lets the engine start. However, if the ID number does not match, it activates an immobilizer that stops the engine from starting.
