Lock cylinder for Milgard sliding patio door

A quick learner from Denver says:
After having the door lock rekeyed, the cylinder is now loose, jiggly and temperamental. The flat pin which protrudes from the cylinder and inserts into the door handle latch is floppy, meaning it has a lot of play. Consequently, The door latch is jiggly but appears to be in good shape. Have you got a replacement lock cylinder? Thanks.
