Lexus, however, goes one step further by offering the SmartAccess Card Key. This is a wallet-sized electronic key that performs all of these functions.

This is achieved an intricate algorithm that is built into the chip in the key. To avoid damage to the key, you should not carry it with sharp objects, like coins or the tip of mechani- cal pencil. The card key should also not be exposed to extreme temperatures or low temperatures. If the battery or card key terminals are wet, they can get corroded and stop your Lexus from starting. The Key Fob The key fob communicates with the vehicle by using radio waves. The key fob is able to lock and unlock doors as well as open the trunk and even start the car with the press of the button.
