Hey all, this may seem obvious but after googling I couldn’t find clear information on how to do this, even the manual is a little unclear.
If your car is unlocked and are unable to lock the car via Central Locking for example if your battery is dead you can lock each door manually
Locking drivers door
Insert key in to bottom of drivers door handle as shown below
And then insert the key in to the lock and turn the key to the right
Refer to How To UNLOCK a MK8 Fiesta MANUALLY (Keyless Entry FAIL!) - YouTube for more information
Locking all other doors
Now this is the part that is not so clear online
Open any of the other doors and look on the edge of the door for this black stopper with a book symbol.
(Below this there is the child lock, this is not the same thing and will not lock the car door if opened from the outside)
Remove this stopper using your fingers and you will see a small hole
Insert the tip of your key in to this and turn (direction depends on side of the car)
The door will now be locked, repeat this for all other doors except the drivers door.
Congrats your car is now secure while you charge/replace your battery.
Note
The doors should either automatically unlock via central locking once battery is charged or can be manually unlocked individually by opening the door from the inside.
