The process for disassembling a Sagitar car key is as follows: 1. First, release the mechanical key (press the button on the top-left corner of the key), then use a tool to tap the fixing pin to the black mark from the edge side. Be careful not to tap too deeply, as it may damage the internal circuit. 2. Next, use pliers to pry open the key cover from the edge. Be cautious not to apply excessive force, as internal components may fall out. 3. Generally, only the key battery needs to be replaced. 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. Disassembling the key yourself carries risks; if you are unable to handle it, please contact a dealer for repair. Additional information about the Sagitar includes: 1. The Sagitar comes standard with 16-inch aluminum alloy wheels, LED high-performance composite taillights, halogen integrated headlights, a windshield with a sunshade area, green UV-resistant heat-insulating glass, and a multifunctional electric sunroof. 2. The Sagitar is equipped with Volkswagen's latest EA211 series engines, including 1.6L and 1.4TSI options, and offers a new high-power tuned version.

Last time I took apart my Sagitar key fob myself, it was pretty straightforward. First, use a small flathead screwdriver to gently pry open the casing from the keyring slot. Be careful not to apply too much force as the plastic shell can crack easily. Once the back cover is removed, you'll see the button battery, usually a CR2032 model. To replace the battery, simply pop out the old one and insert the new one. When reassembling, make sure the rubber gasket hasn't shifted position. The whole process takes about ten minutes. It's best to lay a cloth on the table beforehand to prevent small parts from bouncing away. If any buttons on the key fob aren't working, check for dust on the circuit board while you're at it. Actually, most Volkswagen group key fobs share this design. Doing it yourself saves over 200 yuan compared to going to the dealership.

Disassembling the Sagitar car key is actually not difficult. Let me teach you a safe method. First, use a thin plastic sheet to slide along the side seam of the key to release the clips, avoiding scratches from metal tools. After popping open the back cover, pinch the edge of the battery to remove it, being careful not to touch the gold fingers on the circuit board. When reassembling, remember the battery's polarity—the side with text should face upward. The whole process takes about five minutes, but remember to keep your hands dry during disassembly to avoid static electricity damaging the chip. The key's waterproofing relies on the back cover's rubber gasket, so check if it's properly flattened after reassembly. Many tutorial videos now suggest using a blade to pry it open, but this can easily injure your hands. It's better to invest in a professional prying tool kit, which costs only about ten yuan.

Disassembling the key involves just four steps: locate the gap, pry it open, replace parts, and close the cover. The Sagitar key has a thin seam on the side—if your fingernail can't open it, use an eyeglass screwdriver to wedge in. Stop when you hear a click, then lift the back cover carefully to avoid damaging the ribbon cable. The key point is the positioning groove at the bottom of the key; align the tab when reassembling and press firmly to secure it. Older Sagitar keys reveal a removable mechanical key handle at the final step, while newer models use a one-piece design. Prepare a spare battery if DIY—supermarkets sell them 80% cheaper than dealerships.
