Changan Alsvin V7 key disassembly method: There is a small slot on the back of the key, which can be pried open with a flathead screwdriver. When the car is locked, pressing the lock button on the V7 key will cause the horn to sound twice and the hazard lights to flash twice, making it easy to locate your car in large parking lots. Additionally, holding down the unlock and lock buttons can control the sunroof's opening and closing, which is convenient for ventilation in hot weather. More details are as follows: 1. The Changan Alsvin V7 has dimensions of 4530/1745/1498mm (length/width/height) and a wheelbase of 2610mm, positioning it as a sporty and tech-savvy A-segment car between the Alsvin V5 and the Eado. Its exterior design was completed by a team of post-80s designers at Changan's Turin Design Center in Europe. 2. As the new flagship of the Alsvin family, the Alsvin V7 inherits the development philosophy of 'good-looking, fun-to-drive, and fuel-efficient' from the Alsvin series, which has sold over 520,000 units. From design to technology to driving experience, it fully meets the needs of the post-85s tech-savvy, fun-loving, and sporty generation, setting a new benchmark for value in China's A-segment car market.
I previously disassembled the Changan Alsvin V7 key to replace the battery when the remote stopped working—turned out the old battery was drained. Using a small screwdriver, I gently pried open the side seam until the cover popped off with a click. Inside was a CR2032 battery, which I carefully removed while noting the polarity. After inserting the new battery and snapping the cover back, I tested the remote function—it worked perfectly. Handle it gently to avoid cracking the plastic shell. Keep a toolkit handy; replacing key batteries every 1-2 years saves repair costs. For foldable keys, disassemble the mechanical part first to avoid damaging the switch. DIY is simple and cost-effective—easy to learn!
As someone who frequently repairs cars, I must say that using a dedicated pry tool is the most convenient way to open a key. The Changan Alsvin V7 key usually has clips along the edges; you can locate the position and gently push inward with a small tool to open the cover. The battery inside is a CR2032 model—be careful not to reverse the polarity, as it may affect functionality. Avoid using excessive force when prying to prevent plastic deformation or breakage. After replacing the battery, test it before reassembling. If it doesn’t work, check the circuits instead of forcing it. Most car keys have a similar structure, making DIY repairs feasible, but proper tools are essential—otherwise, spending a little money at an auto parts store for a safe fix is a better option. Remember, if the remote frequently malfunctions, check the battery life first before rushing to replace the entire key.
The first time I disassembled the Changan Alsvin V7 key, I was super nervous, but later found it incredibly simple. Just use an old bank card or plastic piece to pry open the cover along the edge seam—no professional tools needed. Inside, the CR2032 battery is easily replaced, and when reassembling, the cover snaps back into place with a satisfying click. Beginners should avoid using excessive force to prevent scratching the key or injuring their hands. The whole process takes just a few minutes, and after solving the remote issue, it works perfectly for years. If the battery cover is stubborn, don’t panic—take a break and try again later. With practice, you’ll naturally become more skilled.
