Snow and ice can make driving challenging, which is why having new snow tires and the best ice melt solutions on hand can really save you in a pinch. But what if you can't get on the road at all? When moisture gets into the seams around your car doors and freezes, it can make it impossible to open the door by merely pulling on the handle. While methods abound online for opening a car door that’s been frozen shut, many can end up doing hundreds or thousands of dollars worth of damage to your vehicle (yikes). Below, we cover how to open a frozen car door safely with help from Chris Pyle, a Just Answer expert with 20 years of experience as a service technician.

Why Car Doors Freeze Shut

Moisture in door seals and locks

Doors freeze shut when moisture from rain or snow fills seams around the door then freezes, bonding the door to the frame of the car. This usually happens when temperatures drop from above freezing during daytime hours to sub freezing when the sun goes down.

Why frameless and older doors freeze more often

Cars with frameless windows are more susceptible to freezing. This type of window has exposed seals that make it easier for moisture to form between the glass and seal and freeze them together. And since frameless windows sink deeper into the rubber seal, there is greater surface area for the two surfaces to bind together.

You’ll also see doors on older cars freeze more easily as these vehicles usually have worn out door seals that trap moisture, which then freezes when temperatures drop. Older vehicles may have doors that hang unevenly, creating gaps where water can enter and freeze, and older lock components that can freeze more easily.

What Not to Do With a Frozen Car Door

Why yanking can damage handles and seals

Resist the urge to yank on your car door to free it from the ice. Door handles aren’t designed to withstand high amounts of pressure and can snap off, especially in freezing temperatures when materials are more brittle. Pulling hard on a handle can also damage the door’s internal latch and lock mechanisms. Since ice forms on rubber door seals, yanking the door can tear the rubber seal, causing leaks.

The risks of hot water

Social media is rife with videos of people shattering their frozen windshields by dumping boiling water on their car. “When you put hot water onto the frozen glass, rapid expansion and contraction can occur, causing the side glass or windshield to fail,” Pyle says. You can use water safely as long as it’s not too hot. Pyle recommends using water that’s between 50 and 120 degrees. “Any water temp above 32 degrees Fahrenheit will begin thawing the ice and snow,” he says.

Common “internet hacks” that backfire

Along with pouring boiling water on the windshield, other ill-advised Internet hacks for removing ice from a car include applying vinegar, cooking oil, WD-40, or a saltwater solution to the ice to try to melt it. While each of these substances will help melt the ice, they can also damage your car in the process. Salt is highly corrosive to metal surfaces and vinegar’s acidity can damage rubber parts. Cooking oil and WD-40 are oily and difficult to remove once they're on your car and can also damage rubber parts.

How to Open a Frozen Car Door

The methods below can free up a frozen car door without putting your vehicle at risk for damage.

Method 1: Press, don’t pull

Lean your body weight firmly around the perimeter of the door, focusing specifically on the area around the handle and the support beam between the front and rear windows. The steady weight can break the ice without damaging rubber seals or the handle. Use firm, steady pressure instead of hard shoves, and avoid the center of the door. Alternate between pushing and pulling the door handle gently to see if you’ve freed the door.

Method 2: Try a different door first

This may seem obvious but many people don’t think of it. If the driver’s side door doesn’t open, then try a different door. If you’re able to gain entry into your car via another door, climb into the driver’s seat, start the car and get the heat going to thaw out the driver’s side door.

Method 3: Warm the seal safely

While boiling water is not a safe option for melting ice around a car door, you can use warm air. Use a hair dryer set to medium or low heat. “Keep about a six-inch gap and move on once that area has thawed,” Pyle says. “Also, be careful with the fact that the extension cord and device are outside where the snow/ice is. Water and electricity do not mix.” Don’t use a professional heat gun as it produces too much heat and can damage the car.

Method 4: Apply approved de-icing products

If you live in an area that sees a lot of winter weather, then having a commercial de-icing product on hand that you can use to quickly de-ice your car door may make the most sense. These products, which come in a spray can, are designed to quickly thaw ice from car doors, windows, mirrors, and locks. They’re safe for use on your car and can actually prevent refreezing. Just make sure to clean them off after each use. “After doing this, you will want to wash those products off the car within three to 10 days to prevent any type of corrosion where there may be paint blemishes,” Pyle advises.

How to Open a Frozen Car Door Lock

De-icer for locks

Deicing products contain alcohols or glycols that lower the freezing point of water. To unfreeze your lock, you can spray a commercial deicer inside the lock to melt any ice. You can also use a common lubricant. “If water has gotten into the door lock cylinder, preventing your key from working, some WD-40 sprayed into the cylinder normally will fix that right up,” Pyle says.

Warming a key

This method only works with all-metal keys and hence older vehicles. Never attempt to do this with a keyfob or you could ruin its electric parts. While wearing gloves, heat the metal key with a lighter. Once it’s hot, insert it into the lock cylinder and wiggle it around to melt the ice.

Why forcing the key causes expensive damage

Never try to force a key into a frozen lock. Ice and extreme cold make the key itself and the lock’s internal pins brittle. Applying force could snap off the key in the lock or damage the pins in the lock.

Don't break your key by trying to force it into the frozen lock.

Special Situations

Frameless windows and frozen glass

Car doors with frameless windows tend to freeze shut more often (see above); however, you can use the same techniques to free them. Start with gentle pressure around the seam of the door. If that fails, attempt to thaw the ice using a hairdryer or a de-icer spray.

Sliding doors and hatchbacks

Sliding doors and hatchbacks can be particularly vulnerable to freezing since they are generally larger than side doors and have more crevices and seams for water to infiltrate. Often, the best way to free up a sliding door or hatchback is to gain entry into the vehicle through the driver’s or passenger’s side door, then start and warm up the car to thaw out the side doors.

Electric door handles and sensors

Many electric vehicles have electric handles that are easy to damage if you yank on the handle. For flush-mounted handles, such as those found on Teslas, Range Rovers, and other brands, tap around the handle with the bottom of your fist to break up any ice. “If there is exterior ice, sometimes this can crack it and allow the door to open,” Pyle says. Many EVs have defrost features that you can start via their smartphone app.

Modern cars have a variety of sensors to help prevent collisions and lane departures. These features will typically stop working if the car is inundated with snow and ice. Most vehicles will warn you when these features are inoperable. You can get these sensors back online by cleaning off the entire vehicle.

What to Do After You Get the Door Open

Preventing refreezing before driving

Once you get the car door open, use a rag to dry off the seals and contact points around the door frame to prevent it from refreezing shut when the sun goes down and temperatures drop back below freezing.

Inspecting for torn weatherstripping

Once all the snow and ice has melted, inspect the door frame for any torn weatherstripping. Take the car to the shop to have any damaged weatherstripping replaced immediately to avoid leaks and water damage from wet weather.

How to Prevent Car Doors From Freezing Again

Silicone spray and rubber seal treatment

One of the best ways to avoid a frozen car door is to apply a proactive barrier to prevent the contact points between the door and the car frame from freezing together. Silicone-based lubricants like Sonax Rubber protectant or rubber conditioner like Autosol are good options. You can also use petroleum jelly or even cooking spray in a pinch.

Parking strategies in winter weather

There are a few parking tips you can use to prevent your car door from freezing. Park so your car door is facing east. The morning sun will warm the door as it rises, helping to thaw any ice. If possible, park out of the wind, which can accelerate freezing. While parking in a garage is the best preventative for a frozen car door, you can also minimize the amount of moisture falling on your car by parking under a covered area.

Frozen Car Door FAQs

Can frozen doors cause permanent damage?

A car door that freezes won’t suffer permanent damage just by being frozen. It can, however, suffer permanent damage if you use the wrong technique to attempt to open it. Using an unsafe method to force a frozen car door open can lead to torn weatherstripping, broken door handles and latches, shattered glass, and even paint and body damage.

Is hot water ever safe to use on a frozen car door?

Hot water, if it's boiling, is never a safe method for unfreezing a car door. You can use lukewarm water that you pour slowly along the door seams to unfreeze a car door, but even this method has inherent risks.

Why does only one door freeze?

You likely only have one door freezing due to the positioning of the car. A car facing a prevailing wind with little sun exposure will be more susceptible to freezing than a car door that’s protected from the wind and facing morning sun. Worn weather stripping can also impact how likely a door is to freeze. A driver’s side door’s weather stripping will generally wear faster than passenger doors.

When should you call for roadside help?

You should call for roadside help immediately if children or pets are trapped inside the vehicle or if you’re trapped outside the vehicle in life-threatening cold. You should also call for help if the above efforts have failed after 30 minutes of attempting to open the door.
