After Locking/Unlocking the vehicle, Door opening became problematic once again, and now will not open.

It is as though Lock Assembly is locked within itself?

Fault Code: A6E8 not present. JBE Central Locking, repeat interlock.

To clarify: When Plip is used to open Door, the solenoid is audible opening, and the door button lifts to the open position. Using outer/inner handle, no resistance is felt. It is locked.

(Incidentally, when new Door Lock was fitted, if the Door was not locked with Plip or pressing Lock Button down, the Lock worked perfectly).

Wiring problem perhaps?

Checked Fuses in Engine Compartment and Drivers Footwell. Is there a Fuse for each door perhaps? A separate Fusebox for Central Locking?
