FWIW, my driver's side (left) door button stuck in the morning a couple of days ago when I was in northern Quebec (and the overnight temperature had been below zero on the Fahrenheit scale). Happily, I was just able to stick the physical key into the keyhole and pull the button out; I then slammed the door and it shut properly. No problems since then but I did have all the buttons and locks replaced under warranty a few months ago so I do wonder if the fix is starting to fail.
