3 Answers
Sylphy key disassembly method: 1. Remove the mechanical key; 2. Use a flat-head screwdriver to pry open a small gap from the side seam of the key, then gradually pry open the seam along the opening; 3. Insert along the middle seam of the remote control, slowly squeeze, and gently pry outward to open it. The Sylphy is a sedan series launched by Dongfeng Nissan, with dimensions of 4631mm in length, 1760mm in width, and 1503mm in height, and a wheelbase of 2700mm. In terms of appearance, the Sylphy's front face is very imposing, giving a grand impression from the front. Although the size is not large, the proportions of the front, body, and rear are designed naturally, with smooth transitions from the roof to the rear, making it look very rounded and full. In terms of power, the Sylphy continues to use the 1.6L CVT powertrain, paired with either a 6AT or DCT transmission, offering high driving smoothness and exceptionally stable performance.
I previously disassembled my Nissan Sylphy key because the remote wasn't working properly, suspecting the battery was dead. There's a small gap on the back of the key fob, which I gently pried open using a small screwdriver, starting from the edge to avoid scratching the plastic casing. After opening it, you can see the battery compartment - it uses a CR2032 battery. Be careful when removing the old battery to prevent the spring from flying out. When installing the new battery, make sure the positive and negative poles are aligned correctly, then close the cover and press firmly. The whole process took me only 5 minutes, but I recommend doing it in a well-lit area so you can spot any loose components. Actually, DIY is cost-effective and convenient, though for older mechanical-type keys, the disassembly method is similar - just be careful not to lose any small parts. I've also encountered situations where the key malfunctioned after getting wet - regularly checking and cleaning the contacts can prevent failures.
As someone who frequently tinkers with small gadgets, my method for disassembling the Nissan Sylphy key is to first use a fingernail or plastic card to locate the seam along the edge of the key. If you don't have specialized tools on hand, a paperclip or small knife can also work, but be gentle when prying open the clips. The key is to avoid forcing it open to prevent damage to the internal circuitry. Inside, you'll typically find a button battery. When replacing it, opt for reputable brands like Panasonic or TIANQIU to avoid shortening the battery's lifespan with inferior products. After reassembly, test the remote functions to ensure everything works properly. I don't find this task difficult, but beginners might feel a bit flustered, so I recommend watching video tutorials to learn the steps before attempting it yourself. This way, you can save on dealership service fees while also gaining an understanding of the key's internal structure.
