[ArthurDella]

Method for replacing the battery in an old Volkswagen Sagitar key: 1. Before replacing the battery, pull out the key; 2. Turn the car remote key to the back, where you will see the back cover divided into two parts. The side with the key ring has the battery underneath the back cover; 3. There is a gap on the side near the key ring. Push hard to open the tail cover; 4. Pry open the key case with your hands or a screwdriver along the center line; 5. On the back of the key, use a coin or a flat-head screwdriver to pry open the shell; 6. Forcefully separate the side, splitting this part of the key into front and back pieces, revealing the battery and circuit board sections; 7. Follow the reverse order of disassembly to place the battery into the car remote key.
