Can a Car Key Still Work After Being Washed in the Washing Machine?
2 Answers
Whether a car key can still work after being washed in the washing machine depends on the situation. Generally, it can still be used. Emergency repair methods for a car key washed in the washing machine: 1. Use a tissue to dry the surface moisture of the car key, then use a tool to disassemble the key and remove the key blade; 2. Open the outer shell of the car key, take out the battery, then remove the circuit board, and dry the moisture inside; 3. You can use a hair dryer to blow dry the moisture inside, but avoid using hot air, as the circuit board should not overheat to prevent damage during the drying process; 4. After drying the moisture inside, wipe the circuit board and the contact points of the buttons with high-purity alcohol.
Once my car key was accidentally washed by my wife while doing laundry, which scared me so much that I immediately took it apart to remove the battery. You should know that the inside of the key is full of delicate circuits, and water can instantly damage the electronic components. I first used absorbent paper to soak up all the water, then left it by the window to air dry naturally for two full days. In a hurry and thinking of using a hair dryer? Big mistake! High temperatures can warp the components and make things worse. Luckily, my key only had a shorter remote range, so I managed to use it for half a month before finally replacing it. Now I always use a silicone-covered keychain for waterproofing—these small accessories can really be lifesavers. If your key gets wet, my advice is not to hesitate over a few hundred bucks; replacing it outright will give you peace of mind.
