Safe distribution of keys among friends has never been easier: the Key4Friends app receives keys which the owner wishes to share with you from the MobileKey app. The function is quickly explained: the owner of the door sends you an authorisation for one or more doors over the MobileKey web app. You can then open and close the doors concerned using the Key4Friends app. Key4Friends is quick, easy, safe and free to install. You will only be asked for your email during registration. We will then send you a code by text message to check registration. No password is required thanks to the distinct connection between the SIM card and the email address. Important: your smartphone needs to be connected to the Internet to open or close a door with the Key4Friends app. This means that there may be charges, depending on the contract with the operator. Don't worry, though – the amount of data sent is minimal. SimonsVoss Technologies GmbH hopes you have fun sharing keys safely and securely.
