Good idea in general, but kinda missing the mark here.

All of the problems seem from the bad server-side implementation. The company could have fixed all of them with just server-side upgrade, worst case with a mobile app upgrade. The lock itself or its firmware does not need to be modified.

Also, those locks are still being sold, so the after-purchase support does not matter - the locks come broken at the time of purchase.

(yes, the BLE protocol is vulnerable to sniffers and built-in password persists even after full reset. But I think those are pretty insignificant problems given the glaring other problems, and might not be deal-breakers in a lot of cases)
