are you sure that the lock really is engaged? compare the feel and length of travel the knob makes when you fully depress the tremolo. another thing that theoretically can happen is that the knob has come loose somewhat, so that there's a gap between the knob and the base plate, and it slides not between, but under the floating plate when engaged… but then you won't have a downward movement when the lock is engaged.
maybe best would be to loosen the strings and remove the tremolo and have a look whats going on underneath the baseplate.
