As you parse file2 you are neglecting to remove the quotes and the semi-colon, thus the key will never match.

Update: You aren't removing the leading "id " either. Are you sure those are tabs in your data?

Probably best to invoke item 2 from the Basic debugging checklist:

    my ($testKey, $name) = split("\t", $_);
    print "DEBUG: key is '$testKey', name is '$name'\n";
