Can a Car Key Still Work After Getting Wet? The answer is yes. Below are relevant introductions and handling methods regarding car keys: 1. Car Key: A car key refers to the tool used to start and lock a car. Modern car keys all use chips, which are part of a magnetic chip system. The reading coil in the car's ignition lock cylinder will read the chip in the key; each chip contains fixed digital information. 2. Handling Method: If a car key gets wet, do not press any buttons immediately, as this can cause moisture to penetrate the inner layers more quickly. First, dry the surface. If possible, open the key's casing, remove the battery, and use absorbent paper towels to wipe the internal components. Then, use a hairdryer on the cold air setting to dry it—avoid using hot air, as the circuit board inside should not be exposed to excessive heat. Alternatively, place the key in a thin, breathable bag and then into a dry rice container (as rice is highly absorbent and can help draw out moisture).
Getting your car key wet can be really troublesome. That time when it rained, my car key fell into a puddle. I quickly took off the casing and found the battery compartment full of water. Immediate power-off action is crucial—I first removed the battery, dried the surface with tissues, and then used a hairdryer on the cool setting for half an hour. Never use hot air, as it can warp the plastic parts! Inside the key, there’s a small circuit board where water can cause short circuits or rust on the metal contacts. After letting it dry for a day, I reassembled it, and luckily, it still worked. Now, I’m extra careful and use a silicone waterproof case for my key. If it still doesn’t work after drying, the chip might be fried, and you’d need to spend around 400-500 yuan at the dealership for a new one.
