How to Replace the Key Battery for CS75?

[StGabriela]

There are 3 steps to replace the CS75 remote key battery: 1. Use a small flat-head screwdriver or plastic pry tool to gently pry open the remote shell. Be careful not to damage the internal circuits during the process, especially in winter when static electricity should be discharged by touching metal beforehand. 2. For detachable mechanical keys, remove the mechanical key first. You can use the mechanical key to pry along the gap, and the entire cover can be opened once the gap is pried apart. 3. After opening the remote key cover, you will see the battery, which is a CR2032 model. Simply remove and replace it. When installing, pay attention to the positive and negative polarity. After installing the battery, close the key cover and test the function by pressing the buttons.
