Hello, I'm sorry if this has already been asked, but after some searching I can't find any threads that match. I just bought an 04 TB EXT LT 6cyl and it came with 1 key and 1 fob, so I went and bought 2 more keys and they work great. But I also bought another fob and it programmed to the car easily. But then I noticed that the original fob I had didn't work anymore, so I reprogrammed that one and when I did, the new one stopped working. No matter how many times I reprogram each one it's like it erases the other. I don't know why. Please help. I also have access to an Autel scan tool through my work if that can do anything at all to help this. Thank you in advance.
