  •  Start with the aft part of the door sill on the outside. Get your fingers between the rubber weatherguard and the doorsill, lift it enough to get your fingers under the aft part of the door sill. You might need a spider to initially lift the door sill
  •  Pull it away from the plastic piece which has to remain in the car until the metal retainer snaps loose.  It must stay on the doorsill, however, if it stays in the part that remains in the car, you need to wiggle it out with a screwdriver and install it back to the doorsill.
  • On the aft inside of the doorsill there is a plastic clips that needs to be unhooked from the part that stays in the car. Be careful not to break it.

  • However, if you want the aluminium part to remain intact, caution has to be taken, because the aluminium will bent very easily.
  • To make it easier you can use a blow dryer to heat up the aluminium. This makes the 3M take more flexible. CAUTION: Using too much heat will melt the plastic doorsill.

  • Start with prying a (preferable plastic) tool between the aluminium part and the plastic sill, just enough not to bent the aluminium, but enough to get a sharp knife in between, to cut the 3M tape. Work your way slowly to the end by cutting and slowly liftingBe careful not to cut with the knife in the plastic part, since this part remains visible.
  • Continue working your way to get the 3M tape al the way cut, without bending the aluminium strip, and without damaging the plastic
