You now have your battery cover removed. Before you tear the battery that gave you weeks of frustration right out of the thing, take a look at how it's in there so you can put the new battery in correctly. Most remotes have a + sign on the side that gets the + side of the battery facing up, but you'd be mad if yours was the remote that decided not to provide that info.

So stick your new battery or batteries in the hole and you're back in business. Congrats!
