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

[LaMarcus]

Key may not work after being soaked in water. If the soaking time is long and the key has short-circuited due to water ingress, it needs to be disassembled and dried to determine if it can still be used. Here is some additional information: 1. Wipe with tissue: If a car key gets wet, it's similar to a phone getting wet—do not press the buttons immediately, as this can cause water to seep into the inner layers faster. Use a dry cloth or tissue to wipe the surface clean, and use highly absorbent tissue to clean the inside. 2. Dry with cold air: Use a hairdryer on the cold setting to dry the key. Never use hot air, as the internal circuit board should not be exposed to high heat. Alternatively, you can place the key in a breathable bag and then into a dry rice container, as rice is highly absorbent and can draw out moisture. 3. Wipe with alcohol: Use a cotton swab dipped in high-concentration alcohol to gently clean the internal button contacts and other parts, as high-concentration alcohol has strong water-absorbing properties.
