Are you talking about house locks? That would be only technology update.
I do have some lights and machines operated in my house by cable remotes (using house wiring for transmitting signals). The 25 years old remote had a plug for computer. The old-fashioned one, since USB didn't exist at the time. This is so called "Smart house" technology.
Than I bought front door lock with radio remote about 15 years ago. Love it, especially when we can open the front door for kids still unpacking the car.
