Hi and thanks for using 2CarPros.
I feel confident that changing the oil did not do anything to the key.
If you have a spare key, try it. Also, take a look through this link:

If a different key does not work and nothing in the link works, the tumbler may need replaced.
Let me know if any of that helps.
Joe
