I have a 2006 Chevy Cobalt LT with one OEM key, and one OEM Keyless entry remote FOB that the unlock button does not work on.
First, I want to buy 2 more new uncut blank transponder chip keys. I am going to have them cut at a local place that cuts keys. But, my question is how do you program the keys to the 2006 Cobalt (without taking to a dealership if possible)?
Second, I want to buy two new key FOBs (I will stop using the original one once the 2 new ones are programmed). My second question is how do you program these new key FOBs? Is it possible to program them myself without taking to a dealership if I still have the original keyless entry FOB? Does it require a Tech II scanner to program them?
