Can a Car Key Still Work After Falling into Water?

[DeTessa]

Can a car key still work after falling into water? The following are the steps to handle a car key that has fallen into water: 1. If the car key gets wet, do not press any buttons immediately, as this may cause water to seep into the inner layers more quickly. 2. Use a dry cloth or tissue to wipe the surface clean. If you have replaced the battery before, you can open the key's casing, remove the battery, and use absorbent tissue to dry the internal moisture. 3. Use a hairdryer on the cool setting to dry the key. Avoid using hot air, as the internal circuit board should not be exposed to excessive heat. Alternatively, you can place the key in a breathable bag and then put it in a dry rice container, as rice is highly absorbent and can help remove moisture. 4. You can purchase high-concentration alcohol from a pharmacy and use cotton swabs dipped in alcohol to gently clean the internal button contacts and other parts. Then let it air dry, as high-concentration alcohol has strong water-absorbing properties.
