I recently changed coding to switch off the seat belt chime and switch off the lock when drive option. The front doors now will not lock when I use the fob or the interior switch on the door. I returned the codes back but the front doors still won't lock. Back doors and boot are locking fine.
Would this be a matter of disconnecting the battery to re-sync or what could I try?
Any help appreciated.

I re entered the old code and front doors would still not lock. Disconnected the battery, reconnected then locked the car with the key. Light on door stayed on. Unlocked with the key and then locked with key fob. Doors all locking fine again.
