Over
95 % of the time, a song will start and end on the same chord and that
is usually the key.
There are exceptions but they are rare. For songs that fade
out, check out the first chord in the song and the last chord at the
end of the chorus. They will usually match up, and give you
the key.
Where the first chord and last chord are different, you can usually
rely on the last chord as the key.
This is hardly academic but it works way more often than it doesn't.
What it doesn't tell you is anything about the key
you find yourself in.
