What to Do If the Car Key Gets Wet? Can It Still Be Used?

After proper handling, the car key can continue to be used. Here is a related introduction to car keys: 1. Service Life: The battery life of a car remote key is generally about 3 years. When the battery runs out, you need to open the key casing to replace it. Car enthusiasts with strong DIY skills can open the key casing themselves to replace the battery, which is relatively simple. 2. Precautions: The car remote key contains a chip, so be careful not to damage the chip during disassembly. Otherwise, replacing the chip can be troublesome and costly. The casing of the remote key is generally not waterproof, so car enthusiasts should never soak the remote key in water, as this can damage the chip. When using the remote key, try to avoid long-distance remote control, as this will increase battery consumption. 3. Other Precautions: When replacing the battery, purchase high-quality batteries from well-known brands, as they last longer. If the remote key casing gets damaged during daily use, it can be replaced. Car enthusiasts can go to a specialized car remote key shop to get a new casing.
A few days ago, I accidentally dropped my car key into a water basin and was so frantic that I kept stomping my feet. I immediately removed the back cover to take out the battery and used a tissue to dry the water stains on the casing. Taking apart the key is quite simple—just use a paperclip to pry it open. Then, I placed the key in a sealed container filled with rice, as rice has strong moisture-absorbing properties, and left it on the balcony for two days. Never use a hairdryer, as the hot air can easily damage the circuit board. After drying, my key could still unlock the car normally, but the remote control range became shorter. A reminder to everyone: if your key gets wet, cut off the power immediately to avoid burning out the chip. If it still doesn’t work after two days, you’ll likely have to go to the 4S store to get a new key. Smart keys aren’t cheap these days—replacing one can cost over a thousand yuan.
