Can the car key still work if it is immediately taken out after falling into water?

[VonKaden]

The car key cannot be used after falling into water, and do not attempt to start the car, otherwise it may cause greater damage. It is recommended to dry it before use. Here are some precautions for storing car keys: Remove the key promptly: If you need to leave the car, even for just a few minutes, do not leave the key in the ignition. Always turn off the engine, lock the car, take the key with you, and close the windows and sunroof tightly to prevent thieves from taking advantage. Do not leave the spare key in the car: Do not store the spare car key inside the car. Modern car anti-theft systems are generally designed to protect the engine. Even if a thief manages to make a duplicate key to open the door, they cannot start the engine and drive away. However, the spare key can start the engine, so never leave it inside the car, and do not use it as a regular key for long-term use. Understand insurance coverage: When purchasing car insurance, be sure to understand the relevant compensation details for vehicle theft to avoid lacking evidence for claims in case the key is lost and the car is stolen.
