Thought I could add two keyframes with the same value so it doesn't animate, but it simply falls through to the next animation keyframes. So the door still closes, albeit a bit slower.

Not an expert in this but have used it a little. You could control it with a script that only plays the closing animation after some time. Or you could maybe have an animation of the door being open and play that in between? There's a whole state machine for the animations you could use...
