I have a 2005 Dodge Dakota with a Locking Spare Tire Bracket. How to I Get that Off?

You crank the Tire down, It gets to the End of the Mount & Stops but the Cable and Metal Plate keep going, Everything Moves as it should so i know its not Rusted, but it wont Move Past that Daggone Mount.
The mount being the Metal Cone attached to the Truck that holds the Spare tire in Place
