Can a Water-Damaged Car Key Still Be Used?
2 Answers
Water-damaged car keys can continue to be used after being disassembled and dried. Here are the relevant details: 1. Key: Most modern car keys are electronic keys, which are electronic devices. Therefore, do not use them directly after water exposure, as it may damage the internal circuits. You can disassemble the key and dry it with a hairdryer before reuse. 2. Precautions: Electronic keys contain batteries, which may cause a short circuit when exposed to water. Ensure the key is completely dry before attempting to unlock the car. Temporarily, you can use the mechanical key as a substitute. If the key still doesn't work, it's necessary to replace it with a new one promptly.
A few days ago, my car key fell into the swimming pool, and I quickly fished it out and frantically dried it. The key is remote-controlled, and after being soaked in water, the internal circuit might short-circuit or get damp. I placed it in a bag of rice to absorb moisture for two days, and it still worked when tested, but I didn’t dare press the buttons frequently. However, a friend had a similar situation once, and his key was completely ruined, costing him 500 yuan to get a new one. Water can easily corrode metal contacts and chips, so I suggest you remove the battery immediately, dry it with cool air or let it ventilate naturally, and then test the key’s functionality. If it doesn’t work, try the spare key or manually unlock the car door. Personally, I’ve developed a habit of keeping my key in a waterproof bag, and dealing with water exposure promptly to minimize damage.
