How to Open a Key Fob on an Audi

1. Extend the key from the plastic key fob by pressing the chrome button on the corner of the fob.
2. Examine the key fob. Inside the key indentation in the fob (where the key rests when it is not extended). you should see a thin crack. This crack is where the two halves of the plastic fob cover come together. This crack should extend completely around the circumference of the key fob and should run parallel to the fob buttons.
3. Wedge a small flat-head screwdriver into the crack and use the screwdriver to pry the fob apart.
