Wedge keys can be tight, but not really a bit problem tapping out. Do not use WD-40 or any solvent or oil. There is mostly just wood in there, and you do not need to soak that too.

If the key has a central slot that you see is visible as it comes out, it will probably not come all the way out. It is a captured key with a pin holding it under the escutcheon. It does not need to be completely removed. Just enough that the tip of the key passes through the barrel loop in the bottom-center of the barrel set.
