Operation: How to replace the battery in the key of a Mercedes B-Class

Let's start by pressing the button at the top of the electric key of our Mercedes B-Class, so as to free the physical emergency key, and then extract it. After that, we will have to disengage the rear cover of the electric key, and we will have reached the dead battery. We will then have to proceed by removing the battery from its seat. When we have completed this step, the disassembly will be complete. To fit the new battery and close the key, all we have to do is follow this procedure in reverse, and the replacement will be completed.
