Is the battery of our MG 5 key dead? No worries, we can replace it ourselves in no time, without needing to go to a service center and without spending a lot of money. All we need is a small flathead screwdriver and a replacement CR2032 battery.

We will take the key out and, using the screwdriver, we will pry open the joint of the remote shell. On the back side, we will find the battery in question, which we will pull out of its housing and replace.

All that's left is to test it to ensure it works and then close everything back up.
