Frozen locks? Car tips from AAA to keep handy during cold, snowy weather

From frozen windshields, doors and locks to dead batteries - many drivers are struggling in these frigid temperatures.

There's a lot to keep in mind before you grab those keys and head out the door.

A lot of people can't get into their cars because their locks are frozen and they don't have a key fob.

If you're one of those folks, first try the locks on your other doors and do not use hot water on a frozen lock.

Instead, AAA says to use a de-icing product or put a little hand sanitizer or isopropyl alcohol on your key which should allow you to insert it and gently turn.

"You should never pour hot water, boiling water on your car under any circumstances," said Jana Tidwell with AAA.

Tidwell said despite what social media videos circulating show: "It will shatter the windshield."

Also, if your doors or windows are frozen shut, don't force them open.

"You want to use something like a WD-40 spray," she said.

It's also a great idea to apply WD-40 before temperatures dip to prevent freezing.

And if you don't have WD-40, Tidwell said you can use petroleum jelly, a little Vaseline.

"You can also use that in the same way. Just wipe it on the inside of the seal inside the door," she said.

Once you're in your vehicle, the best thing you can do is take some extra time to let your car do its work.

"Just simply starting your car for 10 or 15 minutes will thaw out those things that you need to work in order to safely drive," she added.

Another big issue during the cold temps is dead batteries.

"When the temperature is at about 32 degrees, it takes about a third of the battery's strength just to start your car," said Tidwell. "When we get down closer to zero, it takes more than 60%."

Batteries typically last about three to five years and if you're not sure how old yours is, she suggests to get it checked out.

"It's a quick, just a few minutes test by your trusted mechanic," she added.

A battery test is free at AAA's car centers, even for non-AAA members.

Finally, a lot vehicles have a button that you can press to instantly engage all-wheel or four-wheel drive.

In this kind of weather, it's a good idea to push it before you start to go instead of waiting for your car to sense that you need it.
