Hi guys, I was wondering if you could help me with the central locking on my MK6

- Drivers door lock does not operate with a press of the remote button (a noise is made by the lock which i assume to be the deadlock but the door remains locked)

- Since that problem happened, a new one began, I started using the key alone to unlock the car, but continued to use the button to open the boot lid, the new problem is that the remote will not operate any locks the majority of the time, I have changed the remote battery but its as if the remote is not contacting the receiver in the car


I hope someone can offer help!
Thanks
