Omit the explicit \" quotes. I think you had the quotes on the command line, to prevent the shell from word-splitting (each word becomes an argument).
And, since you are going to use a while loop, prefer the builtin read command.
Code:
while read col1 <&3 && read col2 <&4; do
    keytool -export -alias "$col1" -file "$col2".der -keystore ts.jks -storepass xxxx
done 3< file1 4< file2
