It’s worth noting that many smart locks nowadays have flat capacitive-based keypads, which even I as an able-bodied adult have issues pressing accurately.

I used to live in a place with a main door that was a smart lock and I loved it, now I have to carry keys again which is super annoying.

But one time the battery died while the landlord was out of town, which meant I couldn’t get in my building for hours until his friend was able to find and bring over the physical key backup.
