Kernow Escape: Helston We Have A Problem

It's Christmas Eve and Santa is on his way to begin the Cornish leg of his epic journey but, as there tends to be in this sort of situation, there's a problem!

Kernow Mission Control (which, for the sake of the pun, is based in Helston) is in chaos.  The navigation system is in disarray and badly needs turning off and on again but the security conscious workforce have hidden their authorisation keys and without them, the system cannot be reset!

You have an hour before the man in red arrives to begin this part of his journey.  Find the keys, reset the Sant-Nav and save Christmas for all the children of Cornwall!
