How to Disassemble a Volkswagen Car Key?
2 Answers
Volkswagen car key disassembly method is: 1. Press the button with the elastic switch on the key to pop out the mechanical key; 2. Insert a screwdriver into the gap of the key shell; 3. Pry open the back shell with the screwdriver; 4. Take out the circuit board; 5. Use the key shell to push out the battery; 6. Install the new battery and cover the back shell. Taking the 2020 Volkswagen Tayron as an example: its length, width, and height are 4589mm, 1860mm, and 1660mm respectively, with a wheelbase of 2731mm and a maximum torque of 250 Nm. The car is equipped with an engine model EA211DJS, a luggage compartment volume of 506 to 1590L, front suspension as MacPherson independent suspension, rear suspension as multi-link independent suspension, and features such as cruise control, driving mode switching, automatic parking, and hill start assist.
When removing a Volkswagen car key, I always emphasize handling it gently because there are delicate circuits inside—don't pry too hard and break them. The steps usually go like this: First, separate the key fob from the button section. There’s usually a small notch along the seam where I use a flathead screwdriver or nail clipper to gently pry open one corner, then slowly slide along the edge to open the casing. Be careful not to scratch the battery or chip inside. For battery replacement, older Volkswagen models use a CR2032 coin cell—after buying a new one, align the positive and negative poles correctly before reassembling, then snap the casing shut. If it’s a flip-key design, there might be hidden tiny screws that require a small tool to unscrew before proceeding. I’ve seen many people snap the plastic clips, forcing them to spend money on a new key, so I recommend placing a soft cloth on the table to prevent slipping and avoid working in damp conditions.
