Well that's a twist I've not heard. Where did you get this info? Strange that they would test OK but not program. I don't really need one more key, but if that's actually the case, I'll do it.

That was on forscan forum page or how to page about checking keys. . Someone keys checked good, they erased keys and could only program 1 key, not 2. . Went to dealer and they programmed a second for them.. Their non oem key would not program.

Once they had 2nd oem key, the other programmed apparently.
