Can a Car Key Still Work After Being Soaked in Water?

[ODamian]

Car keys can still be used after being soaked in water and dried. Here are the relevant steps: 1. Do not press any buttons on the car key immediately after it gets wet, as this can cause moisture to penetrate deeper. Wipe the surface dry, open the casing, remove the battery, and use absorbent paper towels to clean the internal components. 2. Use a hairdryer on the cool setting to dry the key—avoid hot air, as the circuit board inside should not be exposed to excessive heat. Alternatively, place the key in a lightweight, breathable bag and then into a dry rice container (rice is highly absorbent and can help draw out moisture). 3. Use high-concentration alcohol to gently clean the internal button contacts and other parts, then let it dry before reinstalling the battery. Note: If the car key is not waterproof, it is crucial to address the issue promptly to prevent long-term damage caused by corrosion or oxidation of the internal circuit board.
