Strange button just below my my coin holder
 

Hi there,

there’s a button that is just below my coin holder just above the latch for the gasoline on the left side driver side. Can anybody tell me what this button is for? I know when I bought it from a dealer that bought this car at auction, it has some kind of remote start feature that use your phone that I decided not to keep from not sure if that’s what this is.

Looks aftermarket.
