What to Do When a Volkswagen Key Gets Wet?

After opening the key cover, remove the internal power supply and use a cotton swab dipped in anhydrous alcohol to clean the circuit board. After cleaning, use the cool setting of a hair dryer to dry the circuit board, then reassemble the key. Below is an introduction to Volkswagen cars: 1. Volkswagen Car Materials: The body steel used is of good quality, thick, and relatively safe. 2. Volkswagen Car Handling Feel: The driving feel is relatively heavy, with strong handling and control. 3. Volkswagen Car Experience: The comfort level is average, with a generally firm suspension. The seats are also quite hard, contrasting with the sofa-like feel of Japanese cars. Volkswagen believes this provides better support and considers softer seats insufficient. 4. Volkswagen Car Interior: The interior includes electronic technology but the design is not very trendy, generally leaning towards stability and moderation. Suitable for both business and home use, the materials and craftsmanship are top-notch, giving a sense of confidence. 5. Volkswagen Car Exterior: The exterior design varies based on individual aesthetic preferences. Most designs lean towards a business-like, stable, and elegant style. Overall, Volkswagen cars are excellent, but compared to Japanese and Korean cars with similar configurations, Volkswagen cars tend to be more expensive.
My Volkswagen car key once fell into a puddle, and I was frantic. I quickly picked it up, shook off the surface water, and then dried the entire key with a tissue. I removed the shell and placed it in a bag of rice overnight—rice does a great job absorbing moisture. The next day, I tested it, but the buttons still weren’t working quite right, so I went to the 4S store and replaced the battery. After that, it worked perfectly! If moisture remains, you can also use a hairdryer on the cool setting from a distance for a few minutes—just avoid hot air to prevent damaging the circuits. Nowadays, I make a habit of keeping my key in a waterproof bag and avoid taking it out in heavy rain or when swimming. Having a spare key is also important; if one fails due to water damage, the other can save the day. In short, quick drying is key—waiting too long can lead to rust and circuit damage.
I own a Volkswagen, and I've researched the issue of key water damage. Since electronic components are prone to short circuits, it can cause button malfunctions or complete failure. The solution is to first turn off any power source, and if the battery is removable, take it out to prevent short circuits. Then, dry the exterior and wrap it in silica gel desiccant or bury it in rice to absorb moisture—don't rush to press the buttons. After leaving it for 12 hours, try unlocking. If it still doesn't work, check if the contacts are oxidized and gently clean them with an alcohol swab. If the issue persists, you'll need to visit a professional shop for repair or replacement—key repairs aren't too expensive. It's recommended to regularly check the battery seal and keep the key in a bag during humid weather to prevent splashes. Prevention is more convenient and hassle-free than repairs.
After my car key got wet, I wrapped it in an absorbent cloth and placed it in the freezer to remove moisture, as low temperatures can help dry out internal water. Wait a few hours, then take it out to warm up and test the buttons. If the results are poor, don't attempt to disassemble it yourself, as this can easily damage the components. Contact the 4S store immediately—they have professional equipment for cleaning. I usually like to attach a small trinket to my key as a reminder to keep it away from water. The key itself isn't expensive, but losing it is a hassle. If it works after drying, there's no major issue, and regularly replacing the battery is also important.
