System Outline: Notes
WARNING: This page is about a different car, the 2008 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
The smart key system is a system to enable the driver, without using the key, to lock or unlock the doors, to unlatch the luggage compartment door and to start engine (Motor). The interactive communication ability of the electrical key allows the vehicle to recognize where the key is. All that the driver has to do is to have the key with them. If the battery in the electrical key happens to run out of battery, then the key can function as a normal key without the smart key system.
