Can a Car Key Still Work After Falling into Water?

[ZaneFitz]

Car keys can still work after falling into water, as modern car keys are designed with waterproof features. If handled promptly after getting wet, they can continue to function. Here are the steps to take if your car key falls into water: 1. Use a tissue to absorb surface moisture and shake out any internal water; 2. Open the key casing, remove the battery, and use a cotton swab dipped in anhydrous alcohol to clean the circuit board and battery; 3. Use a hairdryer on the cool setting to dry it thoroughly. Precautions for using car keys: 1. Do not leave spare keys inside the car; 2. Avoid placing them near electronic devices; 3. Keep them away from metal objects; 4. Avoid dropping the car key; 5. Protect the key from high temperatures, humidity, and direct sunlight.
