Question about 2003 GMC Envoy
At the same time the remote key stopped working, the radio delay with the headlight delay turn off and the interior light all stopped at the same time the back hatch will not lock we are locking manual keyless entry does not work, and cannot unlock back hatch
SOURCE: gmc envoy remote key not working
Sounds like you need a new keyless entry box, but forst try resetting the computer, by taking the positive battery cable off for 10 mins.
If that does not work then seek geting the box for the keyless entry replaced.
