My concern is losing track of keys. I’ve lived in the same house for quite a few years and am far beyond time to rekey. Neighbors have keys, my ex has keys, as does her mom, kids went through so many keys, lawn service, several cleaners, etc. at this point I’m sure I lost track of some.

I like the idea of a smart lock where I can issue and revoke keys at will. It would also be nice to schedule keys, like the house cleaner’s key only works on the day I’m expecting her
