How To: Hack a Car’s Keypad Entry Code

Sweet:

So, you know those cars with that keyless entry pad? The one under the driver’s side handle? Well, if you look closely you will see that there are really only 5 buttons, labeled “1/2”, “3/4”, “5/6”, “7/8”, “9/0”. In an effort to avoid a little confusion, I’m going to call those buttons 1, 3, 5, 7, and 9, respectively.A little experimentation will reveal that, if the code is 11357, and you type 5113579, the door will still open! This means that with 7 characters we managed to try out 3 sequences – 51135, 11357, and 13579. After the inital 4 numbers (which sort of primed the pump) every digit tries one new sequence. Since there are 55 length 5 sequences of characters from an alphabet of size 5, we know that we’ll need to try 3125 sequences total.

They list the entire number sequence on the post.  I highly reccomend you CLICK THE LINK and visit the site.
