Honda SMART Key System
III CA type
The Honda SMART Key system allows you to
operate the main switch without inserting a
key into a keyhole.
The system runs a two-way authentication
between the vehicle and the Honda SMART
Key to verify if it is the registered Honda
SMART Key.
The Honda SMART Key system uses low-
intensity radio waves. It may affect medical
equipment such as a cardiac pacemaker.
