7. Hand Sanitizer
Hand sanitizer can do more than just clean your hands when you’re in pinch, it can actually help you get into your car. Many cars have a keyless system, but if you’re still stuck with the good ol’ lock and key then you may want to think about keeping some hand sanitizer around. If the lock gets frozen and you can’t get your key in, put a little sanitizer on the key and it’ll easily start working. It also helps if your door handle is frozen too.
