I got the 2nd order of remotes in today.
I confused myself a little when trying to program the 2nd remote to the Contour because I didn't finish reading. I was programming the new one, but de-programming the first remote. After like 3 tries, I decided to read the whole sheet and found that I had to program them both together.
Now I have 2 remotes for each car which makes life a lot easier. Hopefully these won't end up in the washing machine like the last ones!
