Reese® TowPower Easy Access Receiver Lock Carded Pack

Went to unlock for first time in months and key broke off in cylinder with virtually no force

Product looks good and sturdy when its put together in the package but when you take it out and put the key in it all falls apart. Plastic around key hole broke off 1st use. Its not actually 5/8" its smaller with a sleeve that will come apart when removing from hitch, leaving it and the O-Ring holding it together in the grass. The key only works sometimes, it doesn't want to sit in the keyhole right, very aggravating when a hitch pin is normally under a truck. This lock is a pain, i returned mine. Also says on package that the product contains chemicals known to cause cancer, that is just crazy. Huge fail by Reese.
