Additional Information
If you think about this lock, it’s great. Setup is easy, but if you want to set up Bluetooth on multiple phones under multiple accounts, let it sit for a bit between setups (I don’t know why, maybe it’s a treatment just like when I reset my router, it takes 3 minutes to see the signal again). Anyway, once you’ve installed it on one phone and tested that it works, turn off that phone or disable Bluetooth and wait 5 minutes (5 actual minutes, time it) then install the second phone. If you try to install them one after the other, you can expect a headache and you might even think it’s defective. Installation was a breeze. It fits into any normal door knob hole.
