Normally, I'd say this is a pretty benign problem: Power door lock actuator: Replace it. Annoying, but not a painful problem (Like my jeeps leaking roof).
But, I wonder about taking the door panels off so frequently: It must eventually lead to rattles and squeaks... Are the door clips/pins easily replaced too???
And after the warranty runs out, somebody like me would have a hard time to fix it in the winter, with no garage. The bitter cold would make the plastic fragile, no? And I can imagine it being difficult to do in a snow storm. I can't imagine having to use my key to get in all the time! It's been years!!! (I leave the jeep's doors unlocked.... The plastic windows are a ~$400 replacement: Nothing in the jeep costs more than $100... let them open the door and steal what they want, just dont slash my windows!!!)
