How to Open a Changan Car Key?
2 Answers
To open a Changan car key, follow these steps: 1. Press and hold the trapezoidal block marked with 'push' on the side of the key without releasing it; 2. Use your other hand to pull out the silver-white strip-shaped key at the top; 3. Insert the larger end of the key into the groove and twist to open the two sides of the key. Changan's vehicle models include: Changan CS35, Changan Yuexiang V3, Changan CS75, Changan Yuexiang V7, Changan Yidong, etc. Taking the 2021 Changan CS75 as an example, it is a compact SUV with the following dimensions: length 4650mm, width 1850mm, height 1715mm, wheelbase 2700mm, fuel tank capacity 58L, and trunk capacity 520L.
I've seen many Changan owners replacing key fob batteries at the repair shop, and it's quite simple. Use a small flat-head screwdriver or a bank card to pry open the seam on the back of the key fob, just give it a gentle lift. Don't use too much force, or the plastic shell might crack. Once opened, you'll see the coin cell battery, usually a CR2032 model, which can be bought for a few bucks at supermarkets or on Taobao. When removing the old battery, push the clip aside with your finger or a plastic tool. When installing the new battery, make sure the positive and negative sides are correctly placed. Close the shell and press firmly until you hear a click, then test the remote range and locking response. By the way, the battery typically lasts about two years. If the buttons feel sticky or unresponsive, it's time for a replacement. The Changan manual has details to prevent mishandling. Check it during annual maintenance to avoid any inconvenience. I've helped a friend replace the key fob battery for a CS75, and it was a breeze. Don't forget to clean the contacts to prevent oxidation, which could affect the signal.
