The procedure to replace the key battery in your 2011 Nissan Sentra is very simple and is practically identical to that used by other manufacturers. First, locate the small button on the back of the cover and press it to fully remove the physical emergency key. Next, using the key itself or a small flathead screwdriver, open the cover and remove the old battery.

Finally, insert the new battery and reassemble the cover, making sure to place the emergency key back inside.
