Remote locking Mazda 3 2010 1.6 petrol

Remote locking suddenly stopped working
Locked using fob, went into shop, five minutes later would not unlock. Had to use the key
Tried spare key / fob, it worked previous day, that didn't work
Both fobs are flashing so batteries okay
Any suggestions

    Possibly need to scan car to see if any errors showing. Although I have a similar problem on a VW and no codes and both remotes with brand new batteries which work on another car. Learned to live with it until I can get it to a specialist to take a look for me.
