I suggest you take another look at the docs. Colorkeys in DDraw are DWORDs.

Direct Draw does not have built in support for alpha transparency. You'll need to write your own blitter or use Direct3D.

You should read the "MMX enhanced alpha blending"-Article if you want to write your own Alpha Blitter. It is very good.

I am writing a simple game, and I am planning on using 32 bit color for it. I noticed that DirectDraw color keys can only hold 8 bit color values, so I was wondering, is there any way to use color keys with 16 or 32 bit color? If not, then how do you do transparency with 32 bit color?
