LOCKING hitch pin

[65SoYoLO]

I have tried 3, and they do not fit easily. The last one will work but it is very difficult to get it unlocked while testing it without anything hooked up. If I had the bike rack hooked up, It might be impossible. I have a non locking pin with just a clip to secure it but i want to be able to lock whatever I have in the hitch.
Anyone have a locking hitch pin that is easy to access?

This one is not bad, I've tried a couple.
