Driver side door lock jammed?

[SubaRyu]

Hi guys,

Seems like my door lock on the driver's side is not working, or stuck. I usually lock the door from outside and this time, it got stuck, and can't open the door anymore. The lock nob from inside is also frozen... can't open from inside as well.

I forced the nob up slightly so that I can open the door from inside. The door opened. I took the inner door panel out and checked, seems like the actuator is the one got stuck.

Is this easy repair or just go get another parts...? Your thoughts are great help.. thanks!
