2005 Prius driver's power door lock

My driver's side power door lock has failed again. This makes twice in the 5.5 years we've owned the vehicle. I don't have my receipt from the last time I had it replaced, but IIRC it was around $200. Does anyone know the part number for this item? I currently have it removed from the vehicle, but can't find a part number for it.

The vehicle is a 2005 Prius with package 6 (JBL audio, NAV and Bluetooth). If anyone can help, I'd really appreciate it. Thanks!
