A standard Cobra door latch will not install easily do too the side impact steel beam in the door. I plan on using a electric solenoid door latch release.

I have not tried to fit them yet, but my CR1 came with rear inner fender liners. That should protect both the latch and the body from road debris.
My car goes (finally) to the body shop next week. He has a lift and we will test fit the liners at that time. I figure I will cut an access hole and add a removable cover for access.
