IMG_9794.jpeg - Bild entfernt (keine Rechte)Hello all, newbie here - I’ve been reading on the forum about security and have found a suitable and recommended wheel lock. I’m very confused about the tow hitch lock. If I can’t find a replacement key, do I need something that covers it to stop it being operated? I’ve attached a couple of photos. To add a little bit of context, I used to be a solo lightweight cycle camper, but now have a wonderful family and a jockey wheel that weighs more than my bicycle frame!!!
