I can't seem to find any screws anywhere on the device to open it up.How do you change the battery on a 2003 Jetta keyless entry remote?
Its kinda tricky, you have to pull the key apart. You will see a line running vertically if you have the key held up longways. You need to pull at each end REALLY HARD and it will come apart in two pieces. Now the part that has the buttons you will have to use a small screwdriver and pry it apart . After prying it apart the battery is right there. If you dont feel comfortable doing it take it to a VW dealer and let them do it for you, it will cost like $20, but a new key is $90, and another $30 to get it programmed to your car.
