KEYS (INTELLIGENT KEY) The Intelligent Key uses coded radio signals to communicate with the vehicle. When the Intelligent Key is near the vehicle, such as in your pocket or bag, it allows the vehicle to be locked, unlocked, or started. It is also possible to use the remote control entry function. - when there are strong signals coming from a television tower, power station or broadcasting station. - when you have wireless equipment or a cellular phone with you. - when the Intelligent Key is in contact with or covered by a metallic material. - when radio wave-type remote control entry is used nearby. - when the Intelligent Key is placed near an electric appliance such as a personal computer.
