Just had the same problem.

The fact the key had not been used in many years the locking mechanism was basically stiff'

Applied copious amounts of wd40 kept turning the key back and forward while applying pressure and release to the boot lid did the trick

I am assuming that the engine won't even turn over. could be lots of different things. The simplist is to make sure the car in in PARK , won't start if not. Other things could be , Security imobilizer if you have one. Does your key have a electronic chip in it ? Try your other set of keys if you have one. Check if battery connections are clean and tight.
