How to Disassemble a Volkswagen Passat Key?

[Maxine]

Volkswagen Passat key disassembly method mainly includes: 1. Unfold the folding key head. 2. Use a flathead screwdriver to pry the gap in the key slot. 3. Separate the key into two parts - the left side with the key head contains the electronic identification chip, while the right side is the battery-powered remote. 4. Separate the remote's housing by prying with a screwdriver. 5. After prying open the remote's housing, you can replace the battery. Additional tip: Press the remote's button to eject the key, which facilitates operation when removing the cover. Hold one side of the key firmly with one hand while using the screwdriver with the other hand to open the cover.

Here's how I remove the Passat key: First, press the small button at the end of the key and pull out the metal key blade. There's a fine gap between the upper and lower shells of the key body—insert a thin plastic sheet or credit card and gently pry it open. When prying, work your way around the edges; don't force it. Once opened, you'll see a green circuit board and a coin cell battery, usually a CR2032. If replacing the battery, remember to use a toothpick to gently flip the battery clip—never poke the circuit board with metal tools. When reassembling, a click means the clips are secured, then just slide the metal blade back in. Avoid using excessive force throughout the process, as plastic clips can break easily, especially on older keys where the plastic has become brittle.

I just replaced the battery in my Passat key last month. It's a simple three-step process: First, locate the metal release button on the side of the key, press it to pull out the key blade. Second, use your fingernail to pry open the shell along the middle seam - a coin works too if you don't have nails. Third, after opening the shell, directly replace the battery, just remember not to install it upside down. The whole process takes about five minutes, saving you 200 yuan compared to going to the 4S shop. Oh, remember to prepare a new battery - the CR2032 type you can buy at supermarkets for about 3 yuan works perfectly. When closing the shell, snap the top part first then press the bottom part for easier reassembly.
