The tricky part is having your key-fob close enough to a transceiver that can then rebroadcast it's signal. Which would no doubt run afoul of broadcast regulations.
Devices like the RTL-SDR work on as receive-only. I'd suggest checking out your local Amateur-Radio club to learn the laws, get a license, and have fun with projects like that.
