keychain garage door opener
All the ones I have seen have a transcveiver you must plug into your garage door system.
One remote I have seen on ebay from Remocon would do the trick except it doesn't do rolling codes. (most garage door openers are rolling codes).
My garage door opener is made by quantum, not a big name thus i need a universal one.
the homelink buttons on the car works fine, but one car will be outside the garage and if someone breaks in the car i don't want them to have access to my house also so i am going to clear the programming on that and carry a keychain remote instead.
It came with two little remotes that looked like the keyfobs from a car. Besides the remote control button for the door lock, it also had a programmable garage door open function, and you could also control an outlet (eg. for a lamp). I never tried it for the garage, though, so I don't know if its any good.
