Its one of those that you will need to assess when there, as lots of different probs dependent upon which type of window lock it is, ie , wafer, spline key , pins etc etc,
Could be a siezed or trapped wafer, could be anything.
go look at it, try jiggling and playing with light tension, try lubricants, last straw , remove lock from window and try shimming or manipulating.
its a question a bit like how longs a bit of string, it really could be alot of different things and alot of solutions dependent on type of lock and type of key stuck in it.
