Replacing the Remote Control Battery in the Smart

Model: Smart Smart 451 - Years 2007-2015
Part: Key

To access the battery compartment in the Smart key, first open the plastic shell by prying it open with a suitable tool at the slot corresponding to the keyring loop. Once the shell is opened, you will find the battery compartment in one half. Extract the battery using a screwdriver or any tool that can provide leverage, and replace it with a new one, ensuring it is the correct type (pay attention to the orientation when installing it). Now, close the shell and test the functionality.
