Flashing security light

[smitz327]

I am pretty sure I went through the programming correctly. I was going to keep trying to program the key a few more times just in case I missed something. I don't have an issue with the light coming on and flashing because it does go out after about ten minutes while driving the car and I haven't had any problems starting it. I guess what I am concerned about mostly is getting stranded. I called my mother back in Pa and she is sending all the spare GM keys that were laying in a draw. Would it cause a problem if I found the other original spare?

I'm pretty sure you'd need to reprogram the keys.
