Wait, wouldn't the backup door just get stuck too if the rail itself is frozen? Good idea from @bell.eric but maybe check the rail first.

Tried one once and it turned "send the report to accounting" into "send the report to clown town". Had to explain that to my boss. Still use it though because talking is way faster than typing, even if it makes me sound like a confused robot half the time. My phone's basic voice notes app does the trick for now, mostly because I'm too lazy to learn a new one.
