How to Open a Changan Car Key?
2 Answers
To open a Changan car key, follow these steps: 1. Locate the trapezoidal block marked with the letters 'PUSH' on the side of the key, then press the end with the letters; 2. Pull out the silver-white strip-shaped key at the top of the key with your hand; 3. Insert the larger end of the key into the groove and twist to separate the two halves of the case. Changan's vehicle lineup includes models such as the Yuexiang, Yuexiang V3, Yuexiang V5, CX20, and CX30. Taking the 2019 Yuexiang as an example, its body dimensions are: length 4390mm, width 1725mm, height 1490mm, with a wheelbase of 2535mm, a fuel tank capacity of 40 liters, and a body structure of a 4-door, 5-seater sedan.
A while ago, I also encountered the trouble of my Changan car key not opening. After pondering for a while, I found out the battery was dead. First, find a small flat-head screwdriver, align it with the tiny gap on the side of the key, and gently pry it open—don’t use too much force, or the casing might crack. Slowly separate the shell into upper and lower halves to reveal the internal circuit board and the button battery slot. Then, use your fingernail or small tweezers to remove the old CR2032 battery, making sure to remember the orientation to avoid installing it backward. After replacing the new battery, don’t rush to reassemble it—press the button to test if the remote lights up and works. Once confirmed, snap the casing back together until you hear a click, indicating it’s secured. The whole process takes about ten minutes, but the right tools are crucial—avoid using scissors or hard objects to pry, as they can damage the key. For regular maintenance, periodically check the battery’s power consumption and avoid crushing the key with other items in your bag to extend its lifespan.
