2014 Prius Driver's side power door lock not working

Hi all - I am new this this site and just registered. I reviewed all the post pertaining to this issue and it seems that it's a faulty power door lock actuator.

Couple things:

Has anyone replaced this on their own? Is it easy? Any tutorials you can point me to?

Has anyone figured other tricks to fix this? I was told unplugging and plugging in the modulator might work.

I am fairly handy, but not sure if it's worth doing it yourself or taking the vehicle in.

If recommended to do it myself, where's the best place to buy one at the best price?

Thanks so much!
