Disassembling the Range Rover Key Fob
I was able to disassemble the key fob without doing too much damage by getting a large blade flat-head screwdriver and gently twisting the blade inside of the recess where the key folds in to.
Once the case started to open up, I got a small flat-head screwdriver blade and gently worked my way around the case until it popped apart.
