Effects of a car key getting soaked in water: The exterior of car keys is generally made of waterproof materials, but there are still some gaps between the keys. If the car key gets soaked in water, it is possible for water to enter the inside of the key, which may cause it to malfunction. It is recommended to repair it as soon as possible. If the car key gets wet, do not press the buttons immediately, as this can cause the water to penetrate deeper into the key more quickly. If the car key is soaked in water, the owner can take measures such as disassembling the interior of the key, wiping it dry with a tissue, and then using the cold air setting of a hairdryer to blow it dry. Alternatively, high-concentration alcohol can be used to wipe it, as alcohol has strong water-absorbing properties. If these methods do not work, the key should be sent to a 4S store for repair.
Getting your car key wet can cause significant issues. Having driven for over 20 years, I've encountered this situation several times. The biggest concern after water exposure is short circuits in electronic components, such as corrosion of the remote control chip or battery contacts, which can lead to key failure, inability to unlock doors, or start the vehicle. Immediately dry the key and remove the battery to prevent internal water damage to the circuits. I often place the key in rice for a few days to absorb moisture, waiting until it's completely dry before reinstalling the battery to test; if that doesn't work, it's best to visit a professional repair shop for inspection or to replace the battery—avoid tampering with it to prevent further damage. Remember, don't use a wet key to avoid potential skin irritation or safety risks. For daily use, I recommend carrying it in a waterproof pouch and keeping a spare mechanical key in the glove compartment for emergencies. Regular checks on the key's condition can also help prevent problems.
