Users can lock and unlock their doors and open their trunks all by using the app. The Keto app features a [two-channel authentication process](https://www.trendhunter.com/trends/channel-sounding) using both Bluetooth and inaudible soundwaves to ensure the app is highly secure. In addition, users can also share the digital key with family and friends on either a permanent or temporary basis with the option to block someone's access at any time. Moreover, the Keto app allows users to set time limits when sharing the digital key. The Keto app can be installed in three easy steps using your [key module fob](https://www.trendhunter.com/trends/playfob).
