So, I have one of these WordLock bicycle locks, and it was cool to learn how to set it up and change the combination.

The only problem is: I forgot what we set the combination to. #sadface

So, without further ado, to programming!

The Scenario:

Lets assume for a moment we know two things:

1. We know there are 10,000 combinations, and that the combination that it is set to is a word in the english language.
2. We have a good understanding of what the word might be if we saw it.

So, with those facts, we’ll need two things:

1. A list of 4-letter words, which we’ll steal *cough* borrow from litscape.com
2. Some programming that goes through every combination possible and compares it to the wordlist

So, the programming:

<?php

function make4($number)
{
        $num = intval($number);
        if (($num < 0) || ($num > 9999))
        {
                die("out of range");
        }
        $ret = "";

        if (strlen($num) == 4)
        {
                $ret = $num;
        }
        if (strlen($num) == 3)
        {
                $ret = "0${num}";
        }
        if (strlen($num) == 2)
        {
                $ret = "00${num}";
        }
        if (strlen($num) == 1)
        {
                $ret = "000${num}";
        }
        return $ret;
}

function combination($number)
{
        $letters = array(
                array('B', 'F', 'R', 'M', 'D', 'T', 'S', 'W', 'P', 'L'),
                array('Y', 'R', 'W', 'H', 'E', 'L', 'O', 'I', 'A', 'U'),
                array('S', 'N', 'T', 'M', 'R', 'E', 'L', 'A', 'O', 'K'),
                array('E', 'T', 'S', 'M', 'K', 'G', 'D', 'L', 'Y', 'P'),
        );
        $code = "";
        $combo = make4($number);
        for ($x = 0; $x < 4; $x++)
        {
                $digit = substr($combo, $x, 1);
                $letter = $letters[$x][$digit];
                $code .= $letter;
        }
        return $code;
}

$words = "";
include('words4.php');
$word = explode(' ', $words);
echo "Loaded " . count($word) . " words\n";

foreach ($word as $w)
{
        $possible = strtoupper($w);
        echo "Trying: $possible\n";
        for ($x = 0; $x < 10000; $x++)
        {
                $code = combination($x);
                if ($code == $possible)
                {
                        echo "Found: $possible\n";
                }
        }
}
?>

I’ve take the space-separated wordlist and saved it as an assignment to the $words variable in a separate file. vim doesn’t do justice with multi-lined non-carriage returned stuff, so I’m cool with that.

After executing the above, from a wordlist of 2404 items, i’m left with 732 possible items.

It is going to be a looooooooooooooooong day 🙁

Edit:

For the sake of justice, none of the above words looked familiar.

I headed over to the wordlock FAQ and did the following:

I can’t open my lock. What combination does my lock open to?
Try of the following factory-set default combinations to open your lock: BOLT, SPELL, PACK, SHED, TREE, GYMS, WORDS.

Seems the factory default worked, which means I NEVER SET THE DAMN LOCK IN THE FIRST PLACE :/
