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:
- We know there are 10,000 combinations, and that the combination that it is set to is a word in the english language.
- We have a good understanding of what the word might be if we saw it.
So, with those facts, we’ll need two things:
- A list of 4-letter words, which we’ll steal *cough* borrow from litscape.com
- 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 :/
