How to Replace the Battery in a Touareg Car Remote Key?

Steps to replace the battery in a Touareg remote key: 1. First, eject the mechanical key from the car key. 2. Use a screwdriver to pry open the outer shell of the Volkswagen Touareg car key by leveraging along the shell's clips. 3. Prepare a new button battery that matches the original key's battery model, which is CR2032. 4. After prying open the key shell, you will see the key battery. Remove the old button battery and replace it with the new one, making sure to distinguish the positive and negative poles (positive side down, negative side up). 5. Finally, align and snap the two halves of the key shell back together to complete the replacement.
Last time my own Touareg remote key fob ran out of battery, I spent a few minutes replacing it myself—it was quite simple. Typically, these keys use CR2032 coin cell batteries, which can be purchased at supermarkets or auto parts stores. First, locate the small notch or seam on the side of the key, then carefully pry open the casing using a thin tool or coin. Be gentle to avoid breaking the clips. Once opened, you’ll see the old battery, usually a small silver disc—note the positive and negative orientation when removing it to avoid installing the new one backward. Insert the new battery, align the polarity, and press it gently into place. Then, snap the casing shut until you hear a ‘click’ to confirm it’s secured. After replacement, test the key: press the unlock button to check responsiveness—if the lights flash normally, it’s successful. It’s wise to keep a spare battery handy to avoid inconvenience during emergencies; replacing it about once a year should suffice.
