I believe the key feature in a micro processor is the how processor frequency and how many processors are in it. But also how much L1 and L2 cache it has.
If you mean the actually key, then it is a manufacturing technique that is used so you can't put a processor in the wrong direction,
In the past processors that were not placed in correctly will damage processor as there was voltage going into places that shouldn't go through.
They use similar features in hard disk data cables and power cables.
