For those who do not want to take the car key, PATEO offers Bluetooth car key based on BCM remote key and anti-theft module, allowing the user to open the car door without waiting or even unlocking the phone. If the mobile phone gets lost, the user simply needs to re-configure the password to receive a new virtual key, while providing the location of the missing mobile phone and the vehicle. With the Bluetooth key, users can easily use car-sharing service with their mobile phone.
