the lock style is the same, so im assuming the key is the same,
however today at my wrecking yard experience, i discovered that the CE wagons have a different ignition barrel arrangement from the CCs, so im inclined to not say they are 100% the same. the CE wagons i looked at had an induction ring (im assuming this means the keys have a transponder in them) where as the CCs didnt.
hope this helps.
