Seized Drawer Problem  

I picked up a very nice item yesterday which had been stored in a cold garage.
After a few hours in my nice warm home the drawers have seized up completely, there is no movement whatsoever.
I am sure a few members must have encountered this problem before. What are my options here?
Leave it for a few days and hope that the timber settles and the drawers free up or maybe put it back into the cold, wait for the drawers to free up and then gradually acclimate it to room temperature.
Any thoughts and suggestions would be most gratefully received.
