Hello, I have purchased a Casio CMD-40B watch. It functions as a remote control for your TV and Cable boxes. How it works is, you look up the specific TV's "code", tell it to the watch, and your watch now acts as the TV's remote control. Here is the Watch Manual http://parsetext.com/0/files.nsf/0/b45a0d96b3011d82882577aa00713fa7/$FILE/qw1174.pdf My question is, could this watch somehow be used to lock/unlock your car's doors using your cars electronic door popper frequency? Seems like a fun project. Thanks!
