Is your 2003 Gmc Envoy Key Fob not working, or did you get a new replacement remote? Programming your key fob yourself can save you time and money compared to going to a dealership. This guide provides simple, step-by-step instructions to program your 2003 GMC Envoy key fob quickly and easily.
Step-by-Step Programming Guide
Follow these instructions carefully to program your 2003 GMC Envoy key fob:
-
Prepare the Vehicle: Ensure all doors of your GMC Envoy are fully closed. Insert your key into the ignition, but do not turn the ignition on yet.
-
Initiate Programming Mode: Press and HOLD the “UNLOCK” button located on the driver’s side door panel. Do not release the button until instructed in step 4.
-
Cycle Ignition: While holding the “UNLOCK” button, quickly turn the ignition key from the “OFF” position to the “ON” position twice. “ON” is the position just before you would start the engine. Do not start the engine. Then return the key to the “OFF” position.
-
Release Unlock Button and Confirm Entry into Programming Mode: Release the “UNLOCK” button on the door. You should hear the door locks cycle (lock then unlock). This lock cycling indicates that your 2003 GMC Envoy has successfully entered key fob programming mode.
Important: If the door locks cycle before you release the unlock button, the programming sequence has failed. You will need to repeat the process from step 1, ensuring you hold the unlock button until instructed to release it. If the locks continue to cycle prematurely, double-check that you are following each step correctly. If issues persist, there may be a malfunction in your vehicle’s keyless entry system, and professional assistance might be required.
-
Program Key Fobs: Take the first key fob you want to program (or reprogram). Simultaneously press and hold both the “LOCK” and “UNLOCK” buttons on the key fob. Continue holding both buttons until the door locks cycle again. This may take up to 5 minutes if you are programming a new, unprogrammed remote. A previously programmed remote will typically pair much faster.
Repeat this step for each additional or existing 2003 GMC Envoy key fob you wish to program at this time, including any original remotes you want to continue using.
-
Exit Programming Mode: Turn the ignition key to the “ON” position. This action will exit the key fob programming mode.
-
Test Remotes: Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly by pressing the lock and unlock buttons.
