Why do you "think" a clip needs to be replaced? Wouldn't it be obvious (snapped)?
Or are you getting a rattle or flimsily attached panel in a spot... and you suspect clips are bad?
For what it's worth, I find the clips on Tesla doors robust. I yanked rear panel off the other day (starting by pulling from the bottom edge) and all clips stayed intact and reusable. You need a plastic spudger of sorts to get behind the tightly fitted panel and car metal... to pry it away enough to get fingers behind the panel in order to pull.
DO be careful to get all the screws out of the panel first from their hidden spots, so you are not pulling against those and tear the panel apart. Rear door has 1 screw under the rubber liner in the bottom of the cubbie/handle/pull, and 2 more screws behind the plastic cover behind the opening lever. Don't know about the front, but is probably similar. Google door panel removal Tesla and watch a youtube.
One thing I double checked before pulling is whether the door panels are hung from window ledge, or not. Tesla door panels are not hung, to get them off you just pull them straight away from the door on all sides including the top. The top edge of clips are different than all the way around the other edges. The top clips are metal.
