Hey guys! I have a 2006 Mazda 3 (hatchback) and I'm having trouble with setting up a key fob. This is not an issue with getting into the programming mode on my car. I can get up to the point of where I am suppose to push the buttons twice on the key fob to program it just fine. (I must have done it 100 times already -_-) The problem is, I can get into the programming mode (doors lock and unlock) but after I push the buttons on the key fob...nothing happens. I know it's suppose to lock and unlock to let me know it programmed correctly, but it just doesn't. My old key fob stopped working month ago and wouldn't work with a new battery. I got a new key fob that is the same as the old one, but neither of them will program to my car now. I'm not sure what else could be the problem at this point?
