Unscrew the latch, insert a flat-head screwdriver into the mechanical keyhole, and rotate to loosen the key latch; 3. After opening the key cover, push the cover forward to remove it; 4. Replace the battery by removing the old one, noting the positive and negative poles, and install the new battery; 5. Close the cover, secure the battery, and push the key cover back into place, pressing firmly to ensure a tight seal; 6. Finally, reinsert the mechanical key to complete the replacement. Precautions for battery replacement: When prying open the car key casing with a screwdriver, align it with the latch position to avoid damaging the key casing. Additionally, ensure the new battery's specifications and model match the original battery.
Last time I changed the battery in my Volkswagen key fob myself, and it was actually quite simple. First, locate the small notch on the side of the key, insert a coin into it, and give it a gentle twist—the back cover will pop right off. Pay attention to the orientation of the old battery. Volkswagen keys mostly use CR2032 batteries, which you can easily find at any supermarket. When installing the new battery, make sure the side with the text faces upwards. You'll hear a 'click' when it's properly seated. Before closing the cover, check if the rubber sealing ring is misaligned—missing this small part can cause water damage to the key. After replacement, test the unlock button response. If the remote range decreases, it might indicate poor battery contact. The whole process takes less than three minutes, much more convenient than visiting a dealership.
