[Train]

I tried using the search and didnt find anything on this topic so I thought i'd ask. I know there are third party smart access/pushbutton set up, but I'm actually looking to retrofit the smart access goods from the brz limited (and sport tech here in canada) into my frs. Unfortunately, I'm not all that familiar with what parts are required so I thought I'd ask if anyone can give me some insight on this matter. Thank you!
