Or get a signal amplifier, although I'm sure that is not legal.

That's it, a garage door opener transmitter with a 500-watt linear
amplifier.

My thoughts exactly. I could open my garage door from anywhere in the
state.

I can't help envisioning the situation. Driver presses the "open"
button, the car's engine labors and stalls under the load of powering
the amplifier, and the garage door snaps open so fast that it rams
right through the back of the garage and skims out into the yard like
a Frisbee (tm).
