My key needs a battery change. Anyone have experience changing it themselves?

Thanks in advance.

 

[list=1][*]Remove the mechanical key from your smart key[*]Inside the slot you just exposed by removing the mechanical key, you'll see a gray piece of plastic.[*]Hold your smart key with the panic button facing you and down[*]Take your mechanical key and press the gray plastic piece to the left.[*]With the gray plastic piece moved left (it's spring loaded) get your thumbnail into the seam at the top of your smartkey[*]Slide the removable section out, and viola - there is your battery![/list=1]

 

Thanks! Now where can I find batteries like that?

 

Take them out, then go to radio shack and show it to them.
