Not sure where your located but i would head to walmart or some place like home depot and pick up a set of screw drivers this way if you ever need them again you will have them also won't cost much and may save you a lot of future hastles. The battery should look like a small plastic brick so to speak once you remove the cover securing it it should pop out make sure you read up on removal though in your owners manual it will pretty much give you a step by step. If you don't have that just do a google search should make it easy on you.
