I only lock mine to the receiver because the locking pin is easier to deal with and I trust it more than the pin with the retainer clip. I don't remove my tow bar and also use an anti-rattle device.
When I got my first tow bar, I locked all the connections with keyed alike locks, but realized it was just something else to service/clean and a pain when connecting and disconnecting. Fifteen years of unlocked tow bar and no issues. To me, camping is about making things simple so that making camp and breaking camp isn't a chore.
