How do you prevent car door latches from freezing?

This is my first winter in Minnesota and I’ve heard rumors that people's car doors will freeze shut. How do I prevent my car door latch from freezing?

The rumors you’ve heard are true, I’m afraid! Luckily, there are a series of preventative measures you can take.
To start, two things you should consider are either parking in a garage or getting a car cover. Protecting your car overnight from the worst and coldest elements is an easy thing you can do.
Beyond keeping your car out of the cold if possible, you can also try:
  • Replacing torn or missing rubber gaskets
  • Wiping down the door frame, making sure it’s clean as possible
  • Covering the rubber with some protective liquid, such as an oil or lubricant
  • WD40 and other rust inhibitors work well inside the lock
  • Installing a remote car starter
Another way to protect your car from the worst of winter is a roadside assistance membership with Jerry.
