Now, there you will be able to have keyless entry into your home by using the “August Smart Lock” coming out later this year.
According to the August website, “the August Smart Lock attaches to your existing deadbolt allowing you to send a virtual key to anyone you choose to have access to your home. Your guests then use their smartphone to gain access to your residence without the need to exchange physical keys. You can specify the duration that the August keys are active for before expiring, or disable them at any time. An August system consists of a small, easy to install smart lock device and a mobile app.”
