Hi Mark, it is more than likely that the door lock has broken in the panel.The door will not close so it will not programme.Open the control panel and look at the lock assy.Is it loose in the panel.Flick the top of the lock till it faces you and it should then programme.You will need anew control panel, they are quite cheap.Any further info needed, please repost. All the best.
