2 Answers
Disassembly method for the new Volkswagen Passat key: 1. Open the folded key head; 2. Use a flat-head screwdriver to pry the gap in the key slot; 3. Separate the key into two parts—one part contains the electronic identification chip along with the key head, and the other is the battery-operated remote; 4. Use the screwdriver to pry open the remote's outer shell. The new Volkswagen Passat has a body length of 4933mm, width of 1836mm, height of 1465mm, and a wheelbase of 2871mm. It is equipped with a 1.4L turbocharged engine, turbocharged intake system, a 7-speed dual-clutch transmission, and front-wheel drive.
Last time my Volkswagen Passat key remote kept malfunctioning, so I opened it up myself to take a look. First, you need to locate the small seam on the side of the key. I used a plastic nail clipper piece to gently pry it open, then slowly separated the casing. Inside there's a small battery, usually a CR2032 model—just replace it with a new one and make sure it's properly aligned. When reassembling, pay attention to aligning the clips, otherwise the cover might not close tightly, making it prone to water damage or vibration failure. This process taught me that DIY can save dealership fees, but be gentle and avoid using brute force to prevent cracking the plastic. Additionally, newer key models might have thinner designs, so checking online for model-specific videos beforehand would be more reassuring. Overall it's quite simple—just use the right tools, like a credit card scrap instead of metal tools to avoid scratching the key's circuitry. After replacement, the car responded smoothly again—definitely worth a try.
