3 Answers
The method to disassemble the Changan Yuexiang V3 key is as follows: 1. Press the silver button on the car remote key; 2. Pull out the mechanical key; 3. Use the mechanical key to pry open the shell. Taking the 2015 Changan Yuexiang V3 as an example, it belongs to the compact car category, with body dimensions of: length 4200mm, width 1650mm, height 1465mm, wheelbase of 2410mm, and a fuel tank capacity of 36 liters. The 2015 Changan Yuexiang V3 is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 101PS, maximum power of 74kW, maximum torque of 135Nm, paired with a 5-speed manual transmission.
To disassemble the Changan V3's key, I'll start with the basic steps. This type of key is usually remote-controlled. First, flip it over and look for a small groove or gap on the key casing. Use a small Phillips screwdriver to gently loosen the side screws—avoid applying too much force to prevent damaging the plastic casing. Once the screws are loose, you can slowly pry open the shell. There might be snap-fit designs inside, so be careful not to break them. After removing the casing, you'll see the battery and circuit board. Use a soft cloth to clean or replace the battery. When reassembling, align the casing properly, tighten the screws, and test the remote function. The best tools for this are a miniature screwdriver and a plastic pry tool, but any small-sized tool at home will work. While disassembling, avoid water or strong static electricity—I recommend working on a dry surface to prevent accidents. If the battery leaks, clean it immediately before installing a new one. For regular maintenance, avoid keeping the key in a pocket where it might get crushed, as this can extend its lifespan.
Every time I disassemble the Changan Alsvin V3's key, it's because the battery is dead, and the process is quite easy. First, feel for the small groove on the back of the key, then gently pry open the gap using the built-in pry tool on the keyring or the edge of an old credit card—no screwdriver needed, as some models are just held together by clips. Once the shell is open, remove the old battery and replace it with a new CR2032 coin battery of the same type, then snap the shell back together and press firmly. Make sure the battery is installed with the correct polarity to avoid reversing it. After reassembly, if the remote control range remains unchanged, everything is working normally. The key is designed very simply, so doing it yourself saves time and money. Just be careful not to cut your fingers on the sharp edges—I keep a small mat handy to prevent slipping. With long-term use, the key shell may warp, so check for looseness after a few disassemblies and seek repairs if needed. Also, avoid exposing the key to high temperatures in the car to preserve battery life.
