I was just given a 09 impala LT but it didn' come with the key fob so I bought a set of 2 online. Just received them today and when I went to program them 2 things happened. Firstly, I can only have one of them programmed at a time? I programmed both several times but only one would work at a time afterward. The one that was programmed second.
Secondly, only the lock and unlock buttons work. The trunk button will not work. The instructions I looked up online simply says to hold down the lock and unlock buttons together until the car beeps. They say nothing about having to program the trunk button separately. The only time the fob trunk button works is while the key reset mode is in use after programming the fob but the second it gets turned off the button will no longer work. Are these simply crappy fobs that I bought or am I doing something wrong?
