Can a Car Key Still Be Used After Getting Wet?

[Savannah]

If a car key gets wet, do not use it immediately or press any buttons on it, as this can cause water to seep into the inner components more quickly. The steps to resolve a wet car key are: 1. Use a dry cloth or paper towel to wipe the surface clean, then disassemble the key and remove the battery; 2. Use highly absorbent paper towels to dry any internal moisture; 3. Use a hairdryer on the cool setting to dry the key—never use hot air, as the circuit board inside the key should not be exposed to excessive heat; 4. Alternatively, wrap the key in a breathable bag and place it in a dry rice container, as rice is highly absorbent and can help remove moisture. A car key is a tool used to operate a vehicle, and modern car keys typically use a chip-based magnetic system.
