Does the car key have basic waterproof functionality?

Car keys do not have basic waterproof functionality. Here are some precautions for using car keys: 1. Do not place car keys together with mobile phones, as the magnetic field interference from phones may prevent the car key from functioning properly. Prolonged exposure to phone frequencies can cause malfunction. 2. Avoid exposing car keys to high-temperature and humid environments for extended periods, and do not leave them under direct sunlight. Additional information: If the car key gets wet, do not press any buttons immediately, as this may allow moisture to penetrate the inner layers. Wipe the surface dry, open the casing, remove the battery, and use highly absorbent paper towels or high-concentration alcohol to clean the internal button contacts and other parts. Use a cold air setting on a hairdryer to dry the key—do not use hot air, as the internal circuit board should not be exposed to excessive heat.
Car keys usually have basic water resistance, such as being able to withstand light rain or splashes, but they are not completely waterproof. Once when I went to the beach, my key fell into shallow water. After picking it up and drying it, it surprisingly still worked and could unlock the car. Many keys are designed with daily exposure to rain in mind and are sealed quite well, but you should never soak them in water for a long time, especially the battery part, as water ingress may cause a short circuit. It's recommended to keep them in a dry place normally. If they do get wet, try opening the cover and blowing them dry. Personally, I make it a habit to wrap my key in a plastic bag on rainy days to avoid accidental damage, as replacing a new key isn't cheap and repairs can be troublesome. Overall, it can handle everyday carelessness, but don't expect its water resistance to be as strong as professional equipment.
