a stupid idea
flip the key over
they work both ways
but some ware more on a over used side

btw my dealer charged $20 FOR THE NEW KEY PLUS 7.50 SHIPPING
SO GET A REAL STEEL KEY NOT A SOFT BRASS COPY

AND YES THE NEW KEY FIXED THE HARD TO TURN PROBLEM
BUT THEN SO DID FLIPPING THE OLD KEY TO USE THE LESS WOREN SIDE
