I would do whatever it takes to get the key in and turned to position 1.

(NOT position 2, but as slk230red documented, position 1).

Maybe spray in tons of silicone spray, and just gently keep moving the key around, spray in more, etc, until it goes in. Then remove the tumbler asap.

Monday, order the correct replacement from the dealer.

Many years ago, I had to have a 190 towed to my indie to replace the tumbler because I let it go too long.
