Drivers Door won't Lock
 

Hi Guys

So a weird thing happened today with my Mazda 3 MPS, I had my key in the ignition with the radio on, and drivers side door was open, then for some odd reason some weird door central locking clicking sounds started to happen. Either I have put the car into a keyless door entry mode? But now I can't lock all my doors? Whenever I go to lock the doors with my remote, it locks then momentarily unlocks? can someone please help me with this issue? I've got to the point where all the doors lock but not the drivers side?

Cheers
