Securing Blue Ox Towbar to Prevent Theft

I've used a standard after market pin lock key unit for 15 years on my Blue Ox Alandan tow bar, never did I worry about it being stolen, especially while on the road, when parked for anything more than 3=4 days, I removed it and stored in a locked storage compartment. Which I understand is another whole story about my neighbors having the exact same key to unlock that storage.
In rv'ing for over 40 years, I never felt that fellow campers were going to steal from me, I always felt safe, and still do.
