4. Step-by-Step Programming Instructions

Here’s a detailed, step-by-step guide to programming your GMC Terrain key fob:

Step 1: Prepare Your Vehicle

Ensure your GMC Terrain is parked in a safe location and the ignition is turned off. Close all doors and make sure the security system is disarmed.
