When winter weather arrives, one of the frustrating challenges that drivers face is when ice build-up leaves a car door frozen shut. It doesn't take an extreme ice storm, frozen locks or doors can be caused by moisture that gets trapped in the seals. This water freezes overnight, making it difficult to open the door. Forcing the door or window frame can cause damage. It's important to use the right techniques and avoid common mistakes that could damage your vehicle.

Don't Do This

  • Forcing the Door Handle: This is not the time for elbow grease. Pulling hard on the handle can break it or damage the locking mechanism.
  • Banging on the Door: Hitting the door can crack the glass or damage the paint.
  • Pouring Boiling Water: The sudden temperature change can cause thermal shock, leading to cracked windows or damaged seals.
  • Using Sharp Objects: While it's tempting to use a knife or screwdriver in the lock mechanism, this can scratch the paint or damage the lock and lead to costly repairs.

Using Warm Water

  1. Prepare Warm Water: Fill a container with lukewarm water. Slowly adjusting the temperature difference is safe. Avoid using hot water, as the thermal shock can cause damage.
  2. Pour Over the Door Seals: Gently pour the warm water over the door's seams, focusing on the areas where ice is likely to form.
  3. Attempt to Open the Door: After the ice begins to melt, gently try to open the door. If it doesn’t open, repeat the process.
  4. Dry the Area: Once the door is open, dry the seals with a towel to prevent refreezing.

Using a De-Icing Spray

  1. Purchase a De-icer Spray: Ensure you have a commercial de-icer spray designed for cars. In a pinch you can apply a 50:50 white vinegar and water mixture with a spray bottle, but this life hack is not as effective and it will take extra time.
  2. Apply the De-icer: Spray the de-icer along the door seams and handle, ensuring you cover all frozen areas.
  3. Wait for the Ice to Melt: Allow the de-icer a few minutes to work on the ice.
  4. Try the Door: Gently pull on the door handle to see if it opens. If not, apply more de-icer and wait a bit longer.

Using a Hair Dryer

  1. Use an Extension Cord: Plug in a blow dryer or heat gun into an outdoor power supply. Use an extension cord that reaches your car if needed.
  2. Apply Heat: Set the dryer to a warm (not hot) setting and direct the heat along the door's edges where ice is present.
  3. Warm the Keyhole (if needed): If the keyhole is frozen, direct warm air into it for a few minutes.
  4. Open the Door: Once the ice has melted, gently try opening the door.

Additional Tips

  • Lubricate the Door Seals: Before winter, apply a silicone-based lubricant to the door seals to prevent freezing.
  • Park Facing East: If possible, park your car with the driver-side door facing the rising sun to take advantage of natural heat in the morning.
  • Don't Force a Frozen Window: Turn on the car's heater and then tackle icy windows with a plastic ice scraper. Trying to roll down an electrical window will break the electrical motor.
  • Cover Your Car: Prepare for miserable weather by using a car cover or a tarp can prevent ice from forming on your vehicle in the first place.
