What do I do if my bottom sash arrived in a locked position and now that it has been installed it will not lock?

The first thing to check is that packers have been placed under the sill directly under the jambs as this then allows the dead load to be transferred directly to the structure without bowing the sill which would then cause the sash not to locate correctly. If the lift hooks have not been fitted at the correct height this can also stop the bottom sash going down far enough and again stop the lock from engaging.
