A decade ago, I soldered a relay directly on the remote to achieve this. It looked terrible with wires hanging out, but it still worked reliably.
Now I just use cheap rf emitters from amazon (you may have to solder an antenna to increase range). As soon as I got an AppleTV, all my switches became available outside my LAN, thanks to Apple Home without having to worry about security.
