Recently I started going to gym, so there were locker rooms in the gym and members had to bring their own locks.
I had a 3 digit tsa dailpad style lock lying around but I couldn't figure out how to set the combination from the default 0 0 0 . tsa is basically the United States's Transport Security Administration, very similar to border patrol. A tsa labelled lock enables tsa to use a master key to open the locks.
So I did some research and manage to find some videos on changing the dailpad numbers. I also did my own video explaining how to do it. It's the 1st time I did a narration type video.
