I have a 07 Nissan Versa, and I think the battery is running low in the smart key.Does anyone know how to change the battery in the smart key?
if there is not a small screw, then check the edges for a small slot and use a small flathead screw driver to pry gently open. inside, you should find a circle shaped silver battery. walgreens or radio shack should carry them. a lot of times the dealer won't charge to replace the battery but they'll mark the battery up a few bucks.
