With the Key ‘n Go App users can lock, unlock vehicle doors and start the engine, right from their smartphones or any other Bluetooth enabled mobile devices. Based on encrypted Bluetooth smart technology, users can securely register new smartphones and share vehicles by sending an authorization code, the same can be done to revoke authorization. Once the digital key is sent and stored in the phone, then the user will be able to operate the phone independently of network coverage.
