Can a Car Key Still Be Used After Being Washed?

[StRosalie]

Whether a car key can still be used after being washed depends on whether it has been water-damaged. Here are the details regarding a washed car key: 1. Water damage and short circuit: If the car key is water-damaged and short-circuited, it definitely cannot be used. Do not rush to start the vehicle to check if the key still works. First, remove the key from the water, use clean paper towels to absorb the surface moisture, then disassemble the key casing, remove the battery, and use a hairdryer to dry the circuit board. Once it's completely dry, test it. If it works, you can continue using it; if not, it will need to be repaired or replaced. 2. No water damage: If the key has not been water-damaged or short-circuited, it can still be used.
