In this day of key fobs, remote start, and smartphones someday some kid is going to say "what's a key" just like my youngest doesn't really know what a record, 8-track, or cassette tape is.
"He" is a she, and her bedroom doesn't have a lock that requires a key. Any small screwseiver that fits the small hole will work.How does he open the lock of his room door? By telekinesis? I, who have worked with electronics since 1959, know when the mechanical backup is most practical and I still use keys, even if my Equinox has a fob.
