The trailer hitch is great, thank you. Unfortunately I have misplaced one lock & all keys. One lock is on where you secure the the ball hitch part. The problem now is that I can not adjust the ball hitches & I can not put it on the truck because I do not have the other locking device. Therefore my trailer hitch is in limbo at this time. So do you have a key I can purchase to unlock the lock that is on the ball hitch? Also can I purchase another lock to secure to the truck? Thank you!
