Just throwing this out there but are you sure thats the door that came on your van? If everything ellse matches it might be a replaced door from a yard. PO may have said screw swapping locks the door popper works fine. might e as simple as popping the lock out and dropping by a locksmith. I have 2 doors on my 01 that the locks don't match my key. I'm 100% sure my slider isnt the original and I'm guessing atleast one of my barn doors isn't since those are the 2 locks I can't use my key on.
Before you go bending a key or breaking the lock might be worth it to pull the tumbler clean with WD40 if it needs it or bring it to a smith to check out.
