Key Programming recommendations

I still haven’t come across anything yet requiring locksmith grade anything. I take that back. We did have an 07 Sebring that we had to raise a white flag to once. Most of my key programming is with Ford, Chevy, and the occasional Honda. There has usually been an OE procedure available in a good aftermarket scan tool. I have a couple flavors of Snap On scan tools (Solus and an old MODIS) and the Autel 908 at work. Both have managed to miss where the other hit for programming like this. I think both did fine for Hondas. GM has always been the old 30 minute relearn procedure, so scan tools are irrelevant. Is there a specific make/model you need to focus on?
