How to Disassemble a FAW-Volkswagen Sagitar Key?
2 Answers
Press the button on the side of the Volkswagen Sagitar remote key to remove the mechanical key from the housing. Here are the detailed steps to replace the battery in the Sagitar key: 1. Locate the switch on the back of the key, pull the top part outward, and after removing the internal metal mechanical key, you will see a small groove. 2. Use a flat-head screwdriver or another tool to pry open the key cover along the groove. Once a gap appears, you can manually open it. 3. After opening the key cover, remove the old battery and replace it with a new one, paying attention to the battery's polarity. 4. Reattach the key cover and insert the mechanical key back into place.
I'm quite familiar with disassembling the Sagitar key, so let me share my experience. FAW-Volkswagen Sagitar keys are mostly folding types. First, locate the small gap or hole on the side of the key, then gently insert a fine needle or small screwdriver to release the clip. Next, carefully pry open the housing with both hands—avoid pulling too hard to prevent internal components from flying out. Inside, you'll find the battery compartment and button board. If the buttons become unresponsive, it's usually due to a dead battery; simply replace it with a CR2032 coin cell, handling gently to avoid short circuits. To prevent losing small parts, prepare a small tray to place them in. When reassembling, align the clips until you hear a "click" indicating proper alignment. After battery replacement, press the buttons a few times to test responsiveness. I typically check annually since battery life lasts about 1-2 years—replacing early prevents failure at critical moments. Additional tip: avoid washing the internals; clean only with a dry cloth or cotton swabs. The disassembly process is straightforward and becomes easier with practice.
