Part: Key

First, press the designated button on the back of the cover and remove the key from the shell.

This will open the shell in two halves, giving you access to the battery: if your aim is to replace the flat battery, simply remove it and replace it. If you want to change the shell, you will need to extract the internal chip from the remote and insert it into a new remote that you have purchased. Good luck!
