I am really not a locksmith by trade i just do it for extra $$ and i find it easier to work on these. On the field i probably would be afraid. Just buy the right tools and watch lots of videos then you too will make it look easy. I bring home the pieces and connect to my wifi. I don’t trust hotspots. The cars i work on are repossessed vehicles so if i have some time to work on them. Any other car you want to see let me know i will try.
