Does anyone know the size of the little screw that holds the transponder key together? I lost mine a while back and it keeps opening up randomly and dropping the battery. I called the dealer and the wanted $6 for the little screw. That’s insane if you asked me !

 

I'll take a guess and say M3 x6mm long. You'll pay about $5-$25 on Amazon for a set of metric screws. Bolt supply warehouse might have one, how much are you willing to spend on gas driving around trying to save money?
