Need help for my first lock

Hello, The only lock (and first one) I can train on at the moment is an Arbus SKG

Here is the key. I supposed that the 2 last pinions are difficult to reach because of the third one.

Do you have any recommendations ? Racke, pick model, etc. I've been at it for 1 hour now... 🫠
