Power locks failing one by one

Hello, I have a 2020 Hybrid LE and a couple years ago both back door power locks failed within about a week of each other.

Once I got tired of manually unlocking and locking the doors for my kids I took it in. The dealership wanted like $1600 to replace both so I passed. I think it is something like a $250 part but you have to take the door apart so I didn't want to try and mess it up.

Now the driver door lock is failing and if the last one goes we're locked out!

Is this a common problem? Anybody found a more affordable solution?
