I have a question. I have a valet key and an original key which are not recognized by the ignition. I tried reprogramming the original key, which seems to work (locks functions as expected during the process), but the green key icon is still seen. I have two other keys that work, but find it odd that the immobilizer doesn't recognize the original key or the valet key. I recently replaced the battery, but I can't find a way to reset the system. Any ideas?
