I'm returning home from a trip and am on my 4th layover in a nightmarish series of delayed flights and last minute changes; when I get home it will be 5 degrees (F) which was not the forecasted temp when I left, so I did not make any kind of preparations and left my car in uncovered long term parking, a 5-ish minute walk from the airport. It dipped into negative temps while I was gone and I'm terrified that I'll get back to a car with frozen locks and no lighter, lock de-freezer, hair dryer, etc, anything to help me get in. I've searched for advice but everything I've read seems to assume you're at home, not at a airport. I'm already so drained and exhausted and it will be late when I get there so I'm just trying to find something, anything that might be helpful in advance before I'm stuck standing outside in unexpectedly, dangerously frigid weather with no plan in jeans, sneakers, and a hoodie. Apologies if something like this has been posted, I couldn't find anything and feel like I'm about to collapse. Any advice is appreciated, even obvious things, I'm sure I may have overlooked something that would be clear to someone else. Posting this before I board my next flight in the hopes there may be some replies by the time I get home. Thank you for reading

Update: made it back, took an Uber home and will pick up my car either tomorrow or the day after during the day. I should have thought of it myself and feel silly that I didn't. Thank you all so much for the feedback, really saved me some stress, I probably shouldn't have driven home even had it not been so cold out with how tired I was. Will definitely use all the advice here to be more prepared when leaving during the winter in the future, no matter the forecast.
