Method to open the Tiguan key: 1. Pull out the mechanical key from the car key; 2. You can see an opening mark at the bottom of the key; 3. Use a small screwdriver to turn the bottom opening mark 90 degrees; 4. Rotate the outer shell of the key to open it. The Tiguan is a compact SUV from Shanghai Volkswagen, with a length, width, and height of 4506mm, 1809mm, and 1685mm respectively, a wheelbase of 2684mm, a top speed of 202km/h, equipped with a 2.0TSI turbocharged direct injection engine, and matched with a 6-speed Tiptronic automatic manual transmission.
I've disassembled the Tiguan key many times. There's always a small groove or gap on the back of that folding key. I usually use a plastic pry tool or an old bank card to gently pry it open - don't use brute force, or the casing might crack or get scratched. Inside you'll find the circuit board and battery compartment, typically using a CR2032 coin cell. When replacing the battery, make sure the positive side faces up. To reassemble, align the clips and press firmly until you hear a click. The whole process takes no more than five minutes, but must be done on a clean, flat surface to prevent losing small components. The main reason for DIY key disassembly is to save money on battery replacement - dealerships might charge around 100 yuan, while doing it yourself costs just a few yuan. If the key stops working, first check if the battery is dead by opening it. Sometimes just cleaning dust from the battery contacts solves the problem. The circuit board is sensitive - avoid touching the circuitry, as damage would require expensive key replacement or reprogramming.
As a hands-on car owner, I've discovered a simple trick for disassembling the Tiguan key. No special tools are needed—just insert a hard plastic piece into the middle seam of the key and gently pry it open. The steps are straightforward: first, extend the key blade to reduce resistance, then lightly pry the clips apart and lay them flat. Once open, replace the battery by removing the old CR2032 and inserting a new one (make sure it's not reversed), then press the shell together until you hear a click. The whole process takes just 2-3 minutes—avoid using metal tools to prevent scratches. I recommend watching online tutorial videos for faster learning and saving repair costs. After disassembly, check the shell for wear to detect aging early and prevent water damage or failure. If you're inexperienced, practice a few times; the key is durable and won't break easily, but use gentle motions—forcing it may damage the clips.
