are you pushing the door in and releasing the handle? Is yours a pass through basement where you can get access from the other side?
My locks have a screw on the back side of the lock, accessed from the back side of the basement door-don't think you get in without damaging the lock but on the other hand do not see how the lock lifts but does not allow the door to open-try pulling harder, maybe it is stuck.
