For garage doors... Yeah, it's been a thing

Because you can sit something there, monitor the rolling codes, then inject so it has a real one.

For a car, you have to follow them around while they lock/unlock repeatedly. And that's only if people are using the button and not proximity. If they're just using proximity, you're going to have to be standing right next to them.

I think most of the wireless attacks aren't trying to be so sophisticated. They target cars parked at home and use a relay attack that uses a repeater antenna to rebroadcast the signal from the car to the fob inside and vice versa, tricking the car into thinking the fob is nearby. Canada has seen a large spike in this kind of attack. Faraday pouches that you put the fob inside of at home mitigates the attack.

So does not leaving your keys by the front door… not that I follow my own advice :-)

Relay attacks don't need the key to be in close proximity, they can be read from almost anywhere in the house if they aren't in a faraday pouch or microwave. Have you seen the size of the antennas these attacks use?
