How to Disassemble the New Passat Key?

[AnnieMarie]

New Passat key disassembly method is: 1. Open the folded key head and use a flat-head screwdriver to pry the gap in the key slot; 2. Separate the key into two parts, the left side with the key head is the electronic identification chip, and the right side is the key battery. The New Passat is a mid-size sedan designed by Volkswagen AG in Germany, with dimensions of 4933mm in length, 1836mm in width, and 1469mm in height, and a wheelbase of 2871mm. The New Passat features a turbocharged intake form, a 4-door 5-seater sedan body type, a 7-speed dual-clutch transmission, and a top speed of 210 kilometers per hour.

I've taken apart my Passat key several times myself. First, locate the small notch on the side of the key and gently pry open the casing using a coin or thin card. Remember to apply even force and take it slow—don't use brute force to avoid breaking the plastic clips. Once the casing is separated, you'll see the circuit board inside, with the small round battery in the middle being the part that needs replacement. Make sure to note the battery model is CR2032, and pay attention to the polarity when installing it—don't put it in backwards. Finally, align the casing and press it back together gently until you hear a click, indicating it's properly assembled. The whole process is really simple, much easier than expected, and doing it yourself saves a good amount of money.

Just helped a friend disassemble this key a few days ago. The key is to find the seam on the casing. You'll notice a thin gap along the side of the key - insert a fingernail or small blade there and gently pry to separate the upper and lower shells. The internal structure is extremely simple, just a circuit board and a coin cell battery. The battery model is CR2032, which you can easily find in supermarkets. When replacing the battery, remember to take photos to record the orientation to avoid mistakes. Before closing the casing, check the snap-fit positions to ensure each one is properly aligned before pressing firmly. The whole process takes about five minutes and isn't complicated at all.

Removing the battery from the new Passat key is actually super easy. First, press the button at the top of the key to release the mechanical key. Then locate the opening along the middle seam of the plastic casing and use a coin to pry it open from the top. Be careful not to use metal tools as they may scratch the casing. After opening, remove the old battery and replace it with a new CR2032 battery, ensuring the side with the '+' sign faces upward. Finally, snap the casing back together, pressing firmly on all edges and corners. The key point is that you don't need any tools to replace the battery - it's a zero-cost operation.

Here's how to disassemble it: First, locate the small notch on the back of the key. Use your fingernail or a credit card to pry open the edges along the gap. Once the upper and lower shells are separated, you'll see the button battery inside, which is a CR2032 model. When replacing the battery, remember to place the black side facing upwards, as this is the positive terminal. When reassembling the shell, first align the bottom clips, then press the top firmly until you hear a click. It's recommended to replace the battery every two years to avoid sudden power loss. The most important thing during this process is patience—never rush or force the shell open.

There's a trick to disassembling the Passat key. First, press the metal key and pull it out. This will create a gap in the key casing, then slowly pry open the plastic shell along this gap. The key is to use finesse, not brute force, as the plastic clips are quite fragile. After opening, simply replace the CR2032 battery, which costs about five yuan at supermarkets. When installing, be careful not to reverse the battery's polarity—the side with the text should face downward. Finally, align the casing slots and press firmly. Once you've done it yourself, you'll understand, and you won't need to visit a repair shop in the future.
