Hi All Happy new year i hope you are keeping safe in these unprecedented times.

So i have my original key (lost my spare) and i tried to copy the key (MAZDA 323f BA) the key was copied and it worked with unlocking the door for a few days then one day on the driver door the copy and the original key does not unlock or lock the door now.

The key starts the car and it unlocks the passenger side. The automatic lock work in that once i lock on the driver side all the doors lock.

I need some advice on what to do to fix the driver side door as it cumbersome everytime i lock on the driver side i have to unlock on the passenger side with the key then lean over to unlock the driver door.

Thanks all

Just to make sure I understand the problem - are you saying that when you turn the key in the driver's door lock nothing happens? With either key?
