2001 BMW 330 BMW E46 330I Deadlocked.

This morning I locked my car via the remote with no issues. But now when I am trying to open it, its not unlocking. The only thing I could do with the remote is unlock the boot. I have tried to use the key to open the door but no joy. However as an emergency lock technique I tried to turn the key clockwise for few seconds and the windows went down. Now I have managed to climb in the car through the window but doors are still locked. Central locking is not opening doors but it does makes a clicking noise when I unlock and when I press lock button the light also flashes with the same clicking noise. I have checked all fuses and they are all fine. I have taken the central locking fuse out and now I can use my key to lock and unlock my driver side door but the rest of the 3 doors are still locked. I have read many articles on internet but no help. Is it a DEADLOCK? How can I Open it.
