Does a PCM reprogram require keys to be reprogrammed also??
I took my truck into the shop the other day for intermittent stalling and hesitation. The service manager told me that he would order a throttle body and reprogram the PCM.
I am not sure that he has reprogrammed the PCM. Do the keys also need to be programmed when they flash the PCM?
