If you want to "do it raht" so that both the existing switches in the
garage operate "normally" and the remote also switches the light on or
off.....
Sounds like you're going to need a DPDT "alternate position" relay wired
into the existing 3-way switch travelers and a momentary rf switch to
pulse its coil and cause the relay to act like a local DPDT switch
that's just been flipped.
HTH,
Jeff
P.S. Can someone give me a good reason why they call those SPDT switches
"3-way switches"? Seems to me they only have TWO positions.

My guess is they usually involve three devices, one lamp and two
switches. Four way's add one or more switches. Maybe it is because the
switches have three wires connected (four ways have four wires.)

A recent post somewhere said it goes back to the Edison days when
'openings' were counted for billing. A switch and a light were 2
openings or a 2-way. Two switches become a 3-way. 3 switches become a 4-way.
