Try the keyfob application found here:
https://github.com/bistromath/keyfob

It's a super-simple OOK receiver which is set up to receive those generic
key fob transmitters and translate them into keypresses. Keep in mind that
garage door openers use a rolling code encryption scheme for security,
similar to car security systems. If you manage to break it, keep it quiet.
