Your car key is one of the most frequently used accessories, so it's necessary to change the battery periodically. Fortunately, this is a relatively inexpensive and simple task.

First, remove the physical key from the cover and use it to gently pry open the plastic cover completely. Next, locate the button cell battery and remove it. Insert a new one, ensuring it is positioned the correct way. Close the cover and place the physical key back into its compartment.
