Why do you think a security key of 4 digits could be enough? Even in hexadecimal digits, this is only a matter of trying no more than 65536 times... (Or gosh, our vulnerable, vulnerable checking accounts :-(
In security, people usually consider 1-2 Kilobytes keys as absolute minimum... How about that?
