My wheelchair doesn't have a key and lock

[jillrabbit]

Hey everyone, I am going to disney in April and I just got a new electric wheelchair that does not have a key or lock. My insurance company paid a lot for it and it also took 6 months of paperwork to finally get it. It's also fitted for me and really comfortable and I am kind of attached to it. I am not sure what I should do. I am obviously worried about it being stolen, but I really want to bring it. Does anyone have any idea on what I could do with it when I get on some rides and have to leave it for a little while?

Thank you so much for your help/ideas!
