For instructions on how to replace the coin-type three-volt lithium battery in your key fob, refer to your Owner's Manual under "Keys and Remote Control." Notes: Do not wipe off any grease on the battery terminals or on the back surface of the circuit board. Refer to local regulations when disposing of batteries.
If you have no power in the underhood fuse box, somewhere between the underhood fuse box and the starter relay is a 175 amp mega fuse. See if you have power on either side of that.
