How to Disassemble the Volkswagen New Sagitar Key?
2 Answers
The steps to disassemble the Volkswagen New Sagitar key are as follows: 1. First, release the mechanical key (press the button on the upper left corner of the key), then use a tool to tap the fixing pin to the black mark from the edge side. Do not tap too deep, as it may damage the internal circuit. 2. Use pliers to pry open the key from the edge to remove the key cover. Be careful not to use excessive force, as internal parts may fall out. 3. If the key malfunctions, generally, replacing the key battery is sufficient. If the key gets wet, you may need to disassemble the internal circuit to dry it. Avoid touching the circuit board to prevent static electricity from damaging it.
I've tinkered with the Volkswagen New Sagitar key a few times myself. It's usually a remote key with a small clip on the back. To open it, the first step is to find a thin plastic tool, such as the edge of a credit card or a dedicated pry bar—never use metal as it can easily scratch the casing. Near the logo on the back of the key, there's a small gap. Gently insert the tool there, and once you feel the clip loosen, slowly pry it open. Avoid applying too much force, or you might break the plastic. Once opened, the casing splits into two parts, revealing the battery and control module inside. If you're replacing the battery, make sure to align the positive and negative terminals correctly—it uses the common CR2032 model, and don't install it backward. Cleaning the internal dust can prevent button malfunctions. Finally, align the top and bottom casings and press them together lightly to snap them shut. It's best to work on a clean surface when disassembling to avoid losing small parts. If you accidentally break something, I recommend buying a new key casing as a backup—they're quite cheap anyway. Before starting, watching online tutorial videos can make the process smoother. Always test the button functions after reassembly to avoid minor issues.
