is there a quick explanation for how to find what key a song is in?

Its usually the first chord or note played.

yeah usually, but since its not the first chord all the time, im not sure and i mess up trying to improvise, theres got to be a logical way to find it, anyone? please?
take a look at all the chords and see what scale the would fit into. For example if you were playing a song with F#, G, B and C, there's a good chance you'd be in E minor (or F# Locrian or any of the corresponding modes after that)
