How to Change the Key Battery of a Volkswagen Polo

Model: Volkswagen Polo MK IV, Polo IV, Polo 4, MK 4, 9N - Years 2001-2009
Part: Key

Here’s how to change the key battery of a Volkswagen Polo: simply lift the flip key and work on the outer edge of the lower part of the remote, on the side with the Volkswagen symbol. If you can manage it with your fingers, or with a small screwdriver, lever off the lower cover until it comes off. Inside is the battery, a common CR2032 that you can find at any supermarket or newsagent for a few pounds. Using the same small screwdriver, remove the exhausted battery and replace it with a new one, paying attention to the polarity. Close the cover and the job is done.
