Step 1: Dry the Key Fob

The first step is to remove the battery from the key fob and dry it out. Use a clean cloth or paper towel to soak up any moisture on the outside of the key fob, and then leave it to air dry for at least 24 hours. You can also use a hairdryer on low heat to speed up the process, but be careful not to overheat the key fob.

Step 2: Check the Battery

Once the key fob is completely dry, put the battery back in and test if it’s working. If it’s not, replace the battery with a brand new one.

Step 3: Resync the Key Fob

If the battery replacement doesn’t work, you may need to resync the key fob with the car’s computer. To do this, follow these steps:

  • Sit in the driver’s seat with your key fob in your hand and all doors closed.
  • Insert the key into the ignition and turn it to the “On” position without starting the car.
  • Press and hold the “Unlock” button on the key fob for five seconds.
  • Turn the key back to the “Off” position and remove it from the ignition.
  • Test the key fob to see if it’s working.

If the key fob still isn’t working, it may be time to bring it in for professional help. In some cases, water damage can permanently damage the key fob’s internal components and render it unusable. However, by following these steps, you can give your VW keyless entry system the best chance at recovery.
