The remote start button stopped working and based on everything I had read online prior to buying the two new fob's, it was a quick, inexpensive, easy fix. I watched numerous youtube videos on how easy it was to take the fob apart, replace circuit boards, swaps out keys. . .bing bang boom done!
Of course nowhere did it say that the GMC key fob is made of impenetrable plastic and good luck mere wimpy human trying to get it open!!
I did finally take the original switchblade key and put it on a new fob - went out to go to work this morning and nope, nothing. The electronics came on, but the engine wouldn't start. So I looked up programming in the owner's manual, followed those instructions and still no working fob. So now, the original fob and the new fob, neither will lock or unlock the doors. I still have one more key fob, but what's saying that one will work either?
Red301 - My truck battery was charged up and working fine last night. The battery in the original fob was working just fine as well. I even swapped the batteries in the fob's, thinking that could have been the problem, because who knows how long the battery that came in the replacement fob had been there.
So now I'll wait for a mobile locksmith, still get charged an arm and a leg for getting a fob programmed, but at least I wont be stuck at home with no way to get to work tomorrow!!
