Is a Car Key Still Usable After Getting Wet?
2 Answers
Car keys that have fallen into water can still be used. Here are detailed instructions for dealing with a wet car key: 1. Steps to take after getting wet: Do not press any buttons immediately, as this can cause water to seep deeper inside. First, wipe the surface dry with a cloth or tissue, remove the battery, use absorbent tissue to clean any internal moisture, and then dry it with a cold air setting from a hairdryer. 2. Repair options: The exterior of car remote keys is generally made of waterproof material, but there are gaps between the keys. If the above methods fail to revive the wet key, it will need to be taken to a repair shop or 4S store for replacement or repair.
A few days ago, I accidentally dropped my car key into a bucket of water, and it got completely soaked—what a hassle! I quickly fished it out and dried it off to prevent the internal chip from being damaged by prolonged soaking, as electronic components nowadays are highly sensitive to moisture. I tried wiping it clean with a dry cloth and then placed it in a bag of rice for two days to ensure thorough drying; remember to wait a while before using it again. If the buttons light up or unlock the car after drying, it means it can still be saved, and the battery might be fine. But if the car doesn’t respond when starting, you’ll need to check the circuitry or replace the battery. Repair shops can usually test it for a fee ranging from tens to a hundred yuan. If it’s completely dead, replacing the key typically costs a few hundred yuan, but don’t lose heart—just remember to use a waterproof case or handle it more carefully next time to prevent this from happening again.
