They're made for mostly elderly, disabled or otherwise mobility hampered people... They are cool, been along time coming for alot of these new know and deadbolts....
Some of the deadbolts have the new WiFi/Bluetooth key-less entry.
Many years ago, Multilock came up with this RFID chip keys to allow a master keying system with one key cut, and then a computer console to control the system of keys....
at the time pretty innovative.... now out there they've done more to the locks themselves then the keys.....
