Old Style Model S Fob - [ Ссылка ]
Here is the updated Model S key fob. This is the newer style and just a tad different than the prior version. All you need is a new 2330 battery and your screwdriver. Pry the back halve off with your screwdriver and remove your dead / weak battery. Place in your new battery and you're all set!
