| By: Christian Brothers Automotive

Winter has its charm, with snowflakes gently falling, children making snowmen, and the world turning into a winter wonderland. But, for car owners, it also brings a unique challenge - waking up to find the car door frozen shut.

It's a common yet frustrating situation, especially when you're in a rush to get somewhere. What do you do when your car door won't budge? Don't worry – Christian Brothers Automotive is here to help with some tips and tricks on how to open a frozen car door.

How Do You Get Your Car Door Open When It's Frozen Shut?

When removing ice from a car door, there is a simple and effective solution: a deicer spray. Hold the spray a few inches away from the door and apply it along the edges and handle. Allow a couple of minutes for the spray to work its magic, then gently attempt to open the door again.

If you don't have access to a deicer or if the lock is frozen, there are alternative methods you can try using household items. Here are some other options to address the ice build-up around your car doors:

How to Unfreeze Car Doors with Vinegar

Vinegar is an easily accessible household item that can defrost your car doors effectively. Here's your quick guide to creating you’re a deicer vinegar solution and how to use it:

  1. Create the Vinegar Solution: Mix equal amounts of vinegar and water in a spray bottle. Shake it well until the solution is thoroughly mixed.

  2. Apply the Vinegar Solution: Spray the vinegar solution around the edges of the car door, the keyhole, and any other frozen areas. The acidic nature of vinegar helps to melt the ice quickly.

  3. Wait and Wipe: Allow the vinegar solution to sit for a few minutes to let it do its thing. Once the ice starts melting, wipe the areas with a soft cloth to remove any residual ice or vinegar solution.

4. Try to Open the Door: Now, attempt opening the door gently. If it's still stuck, repeat the process.

If you choose this method, avoid spraying vinegar on the windows or paint of your car, only use white vinegar, and wear gloves if you have any sensitivity to vinegar.

How to Unfreeze Your Frozen Door Lock with a Key

While a key will typically not fit in the keyhole of a frozen car door, it can still be used to help remove ice. Here's how:

  1. Heat Your Key: Hold the key with an insulated cloth and heat it using a lighter or match for a few seconds.

  2. Melt the Ice: Insert the heated key into the keyhole and wiggle it around gently to melt any ice inside.

  3. Try Opening the Door: Once you've melted enough ice, try opening the door again.

Make sure to use caution when heating your key, and do not touch any hot parts directly. You can also use the hot key to briefly touch the edges of the door in case they're also frozen shut.

How to Unfreeze Your Door with WD40

Although it may sound like an old wives' tale, the multi-purpose product WD40 can indeed be an effective solution to unfreeze your car door. The reason is simple: WD40 is designed to displace water, meaning it can melt away the ice that's causing your door to stick. Here's a step-by-step process:

  1. Shake the WD40 Can: Before you start, give the can a good shake to ensure the ingredients are thoroughly mixed.

  2. Spray the WD40: Spray the WD40 onto the keyhole and around the edges of the door where it's sticking. Be sure not to spray too much – a little goes a long way!

  3. Wait for the Magic to Happen: Allow the WD40 a couple of minutes to work its magic. The chemicals will begin to eat away at the ice, causing it to melt.

  4. Try to Open the Door: After waiting, try to open the door again. If it still won't budge, repeat the process until the door opens.

Be sure to clean off any excess WD40 after you've opened the door, as it can leave a greasy residue that may make it difficult to grip the handle and attract dirt to the outside of your car.

Can You Use Hot Water on a Frozen Car Door?

While pouring boiling or hot water on your car door might seem easy, avoid it at all costs. The sudden temperature change can cause the glass in your door to crack or shatter, leaving you with a much bigger problem than just a frozen door. It can also refreeze quickly, making it even more challenging to open the door.

Here are four other common techniques you should steer clear of:

  1. Forcefully pulling the door handle can break it or the latch, leading to costly repairs. Avoid applying excessive force, especially in cold temperatures.

  2. Using a crowbar or similar tool to pry open the door can cause damage to the frame, sealing, or paintwork. This method may result in expensive repairs that could have been avoided by seeking professional help.

  3. Using a hair dryer or heat gun can damage the paint or rubber seals on the door. Additionally, the use of extension cords can pose safety hazards. It's best to avoid this method to prevent any potential risks.

Above all, remember that patience is critical when dealing with a frozen car door. Forcing it open can lead to unnecessary damage and costly repairs. Take your time, apply our recommended methods, and allow them to work. With a little patience and know-how, you'll be on your way soon.

How to Prevent Your Doors from Freezing

What if we could just prevent your vehicle’s door from freezing all together! If you spray a silicone spray on the door's rubber gaskets that seal the door against the body, this will displace the moisture in/around the gaskets and help prevent the gaskets from freezing over.

Additionally, applying a small amount of light grease to the door key hole can also displace moisture and keep the lock from freezing over. While it is not a guarantee that your door will not freeze, this could save you the hassle and time of trying to open the door!
