Yes but even an unlocked, frozen door can be inoperable.
sounds like the voice of experience...
been there, done that, too! and the door don't open always... at an inconvenient time!! lol I remember my'55 chevy HT... midst of winter... unlocked, but locked out!!!
but the old '61 Vette was the best at it. cold rainy day, she would fill up couple inches in pass compartment... cold, freezing rainy day as I had parked it to go to class... then colder rainy afternoon... and door stuck in lock and jam! oh how I hated it when that happened... lol.... and suddenly the afternoon temps got colder!!!
