Colorado-based company LockState’s RemoteLock 6i (6000i) is an Internet-connected smart lock that connects to your home Wi-Fi network for remote control and monitoring as well as firmware updates. Users of the $469 Lockstate 6000i locks started to fail from last Monday, leaving the keypad entirely useless. The company believes to be about 500 of its smart locks were affected by a faulty over-the-air firmware update last week, which caused a “fatal error” in the locks.
