Living in Nova Scotia, it comes as no surprise that with each winter brings a lot of freezing weather. If you have vehicles, you probably have lock de-icer on hand because cold weather can often lead to a frozen door or a frozen lock.


Yesterday we had a bit of a warm spell, sitting at about 6°C, for much of the morning. However, Environment Canada issued a flash freeze warning for the entire province so I knew colder weather was coming, and fast.


Although I am no stranger to the weather here, I think my brain was also frozen from the -15°C weather this morning because I did something I immediately regretted.


As I was doing a little wishing-for-a-sooner-spring cleaning, there was an item I needed to put in my trunk. Not wanting to procrastinate, I scurried to grab my keys, and pushed the pop-trunk button.


Despite the blast of cold air that hit my face as I opened the door to go outside, I was blissfully unaware of what I had just done — for about five seconds.


Opening my trunk usually takes little more energy than my pinky finger provides. Today, that was not the case. I pulled and banged and scraped the ice, but to no avail. My trunk was frozen shut.


At this point I knew I had to start the car for two reasons. First of all, with no lock de-icer on hand, I was hoping if I turned on the heat it may, by some stroke of luck, flow back into the frozen door of my trunk and thaw it out. Secondly, I knew if I didn’t start the car, my unlatched trunk door would kill my already half-frozen battery.


Twenty minutes later, my car still running, the frozen door refused to budge. I figured my only two options from here would be to either go buy lock de-icer or to find my own DIY solution. I enjoy a good household DIY so I opted for the latter. To my pleasant surprise, my trunk was open less than two minutes later.


The simple solution to my frozen door?

I searched a few options and this is the little miracle I discovered: I mixed 8 cups of cold water — and it must be cold water — with 2-3 tbsp of salt.


After stirring the mix, I went outside again. I slowly poured it along each side of my trunk and along the seam where it meets the window.


Excitedly, I lifted my trunk, only to find it still wouldn’t budge. That’s when I realized I forgot to pour the solution along the bottom of the trunk, by the back bumper.


With another 8 cup solution in hand, I doused that bottom crevice and held my breath. I gave another tug on my frozen door and — voila! — the trunk opened without pause.


I was so excited this simple DIY worked as well as it did. That’s why I just had to share it with you. Let me know if you give it a try, how well it works for you. You won’t be disappointed. In the meantime, don’t forget to be proactive and winterize your vehicle.
