I recently purchased a 2013 Chevy Impala LT in good shape. It came with two keys and key fobs. I ordered batteries because neither of them worked. I changed out the old key fob, however the newer one requires a different battery. I’m awaiting the arrival of that one.
I guess I’ll have to program them again to make these function with my car. How can I go about doing that?
GM has never produced a key fob similar to the one on the bottom, which is for an aftermarket remote start/entry. Just curious as to why someone would equip a car with factory-installed remote start with an aftermarket unit. I assume that something else is causing the key fob to malfunction rather than the fob itself being the issue. Unless someone used a scan tool to unprogramme the key fob from the automobile, they don’t need to be reprogrammed in order to function.
