How to Correct Lock that Seized from Salt Exposure

Question:
I have a van that has a u-haul hitch with a Reese CPP LB10 lock that is jammed. The key is likely corroded from salt. Is there a solution?

Salt is brutal on steel, especially surfaces that you cannot easily see and keep clean, such as the internal parts of a lock. Regular applications of an anti-corrosive like PB Blaster on a new lock can help prevent some of this deterioration but if the lock didn't get this routine "TLC" and is now seized you may be able to dissolve the corrosion but it may take a few applications and some patience while the solvent works.
Apply the spray solvent to the key hole. Try to get as much of the interior covered. If the pin lock can be rotated this will help. Spray the solvent in and leave it for a good while. Rotate it and spray again. Keep repeating this process over 48 hours. The rotation will help ensure most interior surfaces get the solvent. Warming the lock housing may also help; parking it in the sun during application or even using a hair dryer on it might help loosen corrosion after the solvent has had time to work.
If this effort fails you'll need to drill out the lock core and replace the lock with an item like # BD580404.
