A quick script that came to my mind.
However, I always believe that TIMTOWTDI 
use strict;
my $flag = "n";
open FH, '<', 'filename';
foreach (<FH>)
{
$flag = "n" if /\{section\d+\}/;
$flag = "y" if /\{section2\}/;
        if ($flag =~ /[yY]/)
        {
                print $1 if /key2: (.*)$/;
        }
}
close FH;

Update: $flag reset. Thanks to si_lence
