If you could do so, would you ever be in a situation where both cars were
near each other when locking/unlocking? Would
both cars react simultaneously to l/ul command, or only one? More worrisome, would the "rolling code" feature (which I believe exists with our Insights) be compromised or altered in such a situation, leading to unexpected reprogramming or having the remotes inoperative? Or would both cars spontaneously combust?

All joking aside, just curious...
