Here is the method to replace the battery in a Passat remote control: 1. Press the mechanical key button on the remote control to release the mechanical key; hold the mechanical key end with your right hand, with the Volkswagen logo facing upward. 2. Use your hand to pry open the battery cover from the other end along the raised side, exposing the battery. 3. Insert a toothpick into the notch at the edge of the battery and gently pry it out. The battery is a 3V CR2032 alkaline battery. 4. Place the new battery into the battery slot, close the battery cover, and press lightly to ensure it is securely fastened. 5. CR203 alkaline batteries are available in many brands at supermarkets, with little price difference. It is recommended to purchase well-known brands.
I've changed the battery in my Passat remote key fob many times, so let me share some simple tips. First, locate the small seam along the edge of the key fob, usually on the back cover or side. I use a small screwdriver or a hard plastic card to gently pry it open - don't use too much force to avoid breaking the clips. Once opened, you'll see a small coin cell battery, typically CR2032 model, available at supermarkets or auto shops. Remember the orientation of the old battery's positive/negative sides before removing it, then align the new battery properly when inserting. When putting the cover back, press firmly until you hear a 'click' to ensure a tight seal. Test the remote buttons immediately after replacement, like the unlock or panic functions. The battery usually lasts 1-2 years, and humid weather may reduce its effective range. DIY replacement saves dozens in repair fees, and keeping spare batteries in your car brings peace of mind. The whole process takes less than five minutes, but proceed carefully - beginners will get the hang of it after a few tries.
