What is the reason why the car door opens but cannot be locked in snowy conditions?

[JaxsonMarie]

The main reason why a car door opens but cannot be locked in snowy conditions is usually due to the car lock cylinder freezing. Solution: If the lock cylinder is frozen, you can pour hot water into the lock cylinder to thaw it. It is best to add a little lubricating oil to the lock cylinder to prevent freezing next time. At the same time, check if there is an issue with the car lock itself. Prevention methods: To prevent the car door from freezing in winter, you can cover the vehicle with a cotton car cover after parking, which not only keeps it warm but also provides anti-theft protection. Additionally, check if there is any water or damage on the door seals and address it promptly to effectively prevent the door from freezing. If the door is frozen, avoid forcibly pulling the door or turning the key with excessive force, as this may cause mechanical damage. Instead, consider using a portable hair dryer to blow warm air into the keyhole and door seams.
