Why do car doors freeze?
In the winter period, car owners face more problems. Unpleasant situations arise not only on the road while driving. With the first frosts, even getting into the car becomes a challenge. Let’s see what to do if car doors are frozen, how to open them using different methods. We will also talk about prevention of this issue.
Why do car doors freeze?
The main culprit is moisture. When it gets inside the lock or into other opening mechanisms and rubber seals of the door, it freezes at low temperatures. This leads to frozen doors. Ice can also block the lock cylinder, keyhole, or other elements.
Main reasons for freezing locks and seals
There are several main reasons why car doors freeze:
- A large temperature difference between inside and outside of the car causes condensation;
- Rapid temperature drop below zero after rain;
- Temperature drop with high humidity or after fog;
- Moisture getting into the lock during a car wash;
- Poor wiping of the door frame and rubber seal after washing;
- Snow entering the gaps.
The main cause of freezing is condensation, formed due to temperature differences and weather conditions.
How do weather conditions affect car mechanisms?
Weather conditions affect most car mechanisms. This impacts the fuel system, transmission, suspension, body, and other elements. For example, rubber parts become stiffer and lose elasticity in subzero temperatures. This also affects bushings, making the suspension work feel unusual.
In such conditions, rubber seals also lose elasticity. Sometimes this even leads to water leaks. Condensation or other precipitation, with the first frost, causes the doors to freeze.
If moisture gets inside the lock, the temperature doesn’t even need to drop below zero for it to freeze. Metal parts are more sensitive to low temperatures. They can get covered with ice at slightly above zero degrees. In frost, the lubricant on these parts becomes ineffective and makes mechanism movement more difficult.
First aid: what to do if the door is frozen?
If car doors are frozen, do not:
- Try to forcefully turn the key;
- Pull the door handle with force;
- Pour boiling water on the door.
The problem is often caused by frozen condensation on the seal. Therefore, try:
- Tapping around the perimeter of the door.
- Pushing the door slightly.
- Checking the other car doors.
Tapping can crack the ice on the seals, allowing you to open the car. But if the lock is frozen, tapping alone will not help. You will need to defrost the mechanism.
Remember, you can also get into the car through other doors. Check if one of them opens. The trunk can also be used, for example, in station wagons, minivans, or vans. Typically, the door used least often opens more easily. Once inside, start the car and let it warm up to open the other frozen doors.
