Passenger door not opening from inside or outside - Help!

[Ninj43]

Yeh remove the external handle, then disconnect the cable from it to rule out any tension stopping the mechanism from being operated correctly by the internal handle/cable

Forgive my ignorance, how can I remove the external handle without opening the door? It looks like the barrel needs to be removed first

I assumed it was the passenger side?
Is it drivers?

 

[getJDt6]

Yes it's the drivers side, sadly. So unable to take lock out

To update, managed to open the door by using a drill on hammer setting at low speed to vibrate the lock. Popped open within about 20 seconds! So relieved. Make thanks for your help anyway.
