I had to pair this with my device about half a dozen times to get it working. It says it must be within 15 feet to work. I've tried the exit at 15ft, then maybe 7ft, to no avail. The key is now about 2-3 feet from the device and is working. Even when it was in that location I had to pair it multiple times as the lock said it couldn't connect to Wi-Fi and at times it said it had disabled Bluetooth entirely. It's been about 12 hours and the lock is now working as advertised.
