I decided to buy a switchblade key with a built in fob for my 2007 zx3. I got the key cut, and the remote programmed and everything worked perfectly. Then a little while later, I attempted to unlock the car with one of the original fob and it wouldn't unlock. The car had forgotten it. I have tried reprogramming them individually, and I have tried programming all 3 fobs at the same time. It always works temporarily, then forgets one or the other. Are there any solutions for my problem?

which switchblade key did you get? There are several kinds out there. The one I had, had everything in it and only needed it to be cut. There is another kind where you transfer over the fob and pats chip?
If the fobs that are forgetting the programming are old i would replace the battery, and then reprogram all 3 at the same time.

Mine was the same as yours. Having the key cut was all that was needed to be done. I have tried reprogramming all 3 at the same time, and they work temporarily, but are forgotten within hours. I had no problem whatsoever before I got the new one.
