This makes it difficult to get said keys but not impossible.

All you'd need is to open the chip and apply a fairly powerful microscope to 
it.  I think you can see the state of flash or PROM gates, and even if not, 
nothing's stopping you from probing it.

This increases the barrier, but does not remove it.
