Why are key fobs standard for cars but not doors? : Locksmith

With a car’s remote key fob, you can easily lock/unlock your car from a distance, and this is standard technology.

I know there are app-based smart locks and other NFC-type “touchless” locks for homes/businesses, but why isn’t there simple remote locking technology that’s //standard// for doors, like the front door to one’s home?

Not sure if this is the best sub to post this question, so please let me know if there is somewhere else I should go. Thanks!
