2005 Ford Explorer Sport Trac door code recovery

Forgot your door code? Bought a used Explorer and previous owner didn't share the code? Now you can find out quickly and easily what the default factory code is, and then you can set your own custom code.
Note: this video was originally published in 2015 and my collection had thousands of views, likes, and comments from people whom it helped, before YT changed their terms, eventually resulting in the loss of all my published video collection and stats. So as I try to rebuild from that disaster, I'd appreciate if you could help by liking and subscribing. Thank you!
