What is the disassembly method for Volkswagen car keys?

[StSienna]

Volkswagen car key disassembly method is as follows: 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 housing. 3. Pry open the back cover with the screwdriver. 4. Take out the circuit board. 5. Use the key housing to push out the battery. 6. Install the new battery and close the back cover. Extended relevant information is as follows: Taking the 2020 Volkswagen Tayron as an example: 1. Its length, width, and height are 4589mm, 1860mm, and 1660mm respectively, with a wheelbase of 2731mm and a maximum torque of 250 Nm. 2. The engine model equipped in this car is EA211DJS, with a trunk 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.

I often disassemble Volkswagen car keys myself because repair shops charge too much. When disassembling, you need to prepare small tools: a small flathead screwdriver or a plastic pry tool. Find the small gap on the back of the key or the gap near the button, gently insert the tool to pry open the shell, and never use brute force, otherwise the plastic may crack. Remove the old battery, pay attention to the positive and negative markings to avoid installing it backwards. Clean the internal contacts if they are dirty, use a cotton swab dipped in alcohol to wipe them, avoiding poor contact. When replacing the battery, choose the correct model, such as CR2032, to ensure the voltage is appropriate. Be patient when reassembling and press the cover tightly until you hear a click, indicating it's locked. I always wear anti-static gloves to protect the circuit board and prevent short circuits. Remember to test the key functions; if it doesn't work, check for circuit issues or the need for resynchronization. Doing it yourself is quite worthwhile, saving hundreds of dollars!

I've taken apart my Volkswagen car key several times myself, and it's quite fun. Before starting, find a quiet place and prepare basic tools like a screwdriver or a credit card to use as a pry tool. There's usually a small gap on the back of the key—insert the tool and gently pry to slowly separate the casing. The battery is inside; remove the old one and note the model, like CR2032, to buy a new one at the store. Clean the contacts with a damp cloth, but don’t use too much water. Install the new battery with the positive side facing up, then press the cover firmly and align the clips. You can save dozens of dollars each time. I often share this with friends, and they find it simple to learn. Just be careful not to lose small parts—the whole process is quick and takes about 10 minutes!

My family and I share a Volkswagen car, and I remove the key myself to avoid hassle. Use a small screwdriver to pry open the key shell, carefully targeting the gap to avoid damage. When replacing the battery, choose the correct model, such as CR2032, and clean the contacts to prevent failure. After reassembly, test the remote functions to ensure responsiveness. Doing it yourself is simple, cost-effective, and even kids can learn it—saving time and hassle compared to waiting for repairs.
