K, the Key, is to be moved to contact L, the Latch, so as to move it totally into the grey area.

Locked
 K → L →
Open
 L

 1 3 2 8 9 10 K → 5 L → 4 6 11 7

The object again is to move K to dislodged L. The "tumblers", the numbered blocks, are only to slide in the direction of their respective lengths.

How might you accomplish this?

Note: the black areas are void space.

Yes, I think there is a mistake... you can't move 8 and 9 without moving 6 or 3.

My solution is,
Move 1 left (1 square - void space)
Move 2 left (1 square - void space)
Move 5 up (2 squares - void space left by moving 1 and 2)
Move K right (1 square - space left by moving 5 up)
Move 4 up (1 square)
Move 7 left (2 squares - space left by moving 4 up))
Move 6 left (3 squares - space left by moving 4 and 5)
Move 3 left (1 square - space loft by moving 1)
Move 8 and 9 down (2 squares - space left by moving 6 and 7)
Move K right (2 squares - space left by moving 8 and 9)
Move 10 up (space left by moving 3)
Finally, move K right, so moving the latch L into the grey area.
