I will install all exterior doors with the Level Lock Pro. This lock will support Apple HomeKit, Google Home, and NFC key fobs for those without a smart phone. The deadbolt does not stick out like a sore thumb, and looks like any other lock from both the inside and outside. To gain access, you will bring your device up to the lock, and if authorized, the door lock will unlock and allow access. And while there is a key hole, the key will not be provided. Instead, the key remain in my safe. As a precaution, I will have a locksmith to setup the locks where only 1 key is needed. Again, I will be using my devices such as phone, or watch to enter my home.
