Hit Remote Control Thomas

I got a Thomas at the flea market for a buck. It needed to be cleaned and seems to be getting power as the red light blinks. So then I went on eBay and bought what I thought was the remote, or my best effort at a guess. They are both made by HIT so I thought I was good






I took them both apart thinking there might be a code (like remote ceiling fans). Not so lucky

Any advice on if what I have is correct and if it’s operator error or perhaps how to make sure that if we get another remote that it’s the correct one
