So the remote is constantly transmitting, and the car is constantly looking for the matching frequency for hands-free. And ignition of course.
To clone it then, a would-be thief would have to be pretty close. They couldn’t be in a car way down at the end of the aisle in a parking lot. They’d have to be within a car or two of yours.
Just be vigilant when you park. Look for suspicious people sitting in cars near you.

Makes sense, Olrocker. I'm still interested if the FOB is transmitting that signal 20 or 30 feet away, though, without a press on the FOB for people to intercept.
But I ordered the Faraday arpad_m mentioned, and after I start my car I'll just put it in that, then manually lock my door when getting out, and keep the FOB in there till I get close to my vehicle for the proximity signal to kick in to unlock my car.
What a PITA.
