It’s called a Security Relearn, and it typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This simple sequence syncs the new module to your vehicle, ensuring a successful start-up without a trip to the shop.
Guided Installation to Restore Your Envoy’s Health
