closed, depress the key lock (if equipped) with your

finger, or spin the combination dial one full turn.

For greatest security, do both. (Make sure the door
handle is in the horizontal position.) There is a link to the manual at the bottom of this page...

A locksmith would try to replace the batteries. Sometimes you will get the green light but the batteries still will not have enough power to retract the latch.

The door lock could be jammed try shacking briskly to losen lid and latch! akso it may have reset itself and the combo is no good no more and back to the origanal setting it had when you bought it ! ( if its a 911 you can put a screwdriver in where key goes and turn hard counter clockwise)
Good Luck!
