Lost your key fob or need to program a new one for your 2003 GMC Yukon? Don’t worry, programming your key fob can be a straightforward process you can handle right at home. This guide will walk you through the steps to program your 2003 GMC Yukon key fob quickly and easily.
Step-by-Step Programming Instructions for Your 2003 GMC Yukon Key Fob
Follow these simple steps to program your 2003 GMC Yukon key fob:
-
Get Inside and Prepare: Enter your 2003 GMC Yukon and ensure all doors are completely closed. Insert your key into the ignition, but do not turn it on just yet.
-
Initiate Programming Mode: Locate the UNLOCK button on the driver’s side door panel. Press and HOLD the UNLOCK button down. Do not release it until step 4 instructs you to do so.
-
Ignition Cycling: While holding the UNLOCK button, quickly turn the ignition key from the OFF position to the ON position and back to OFF twice in rapid succession. The “ON” position is the position right before you would start the engine. Do not start the engine.
-
Release and Listen: Release the UNLOCK button. You should hear the door locks cycle (lock then unlock). This lock cycling indicates that your 2003 GMC Yukon has successfully entered key fob programming mode.
Troubleshooting Tip: 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 one, ensuring you hold the UNLOCK button until instructed.
-
Program Your Key Fob: Immediately after the locks cycle, take the first key fob you want to program. Simultaneously press and hold down both the LOCK and UNLOCK buttons on the key fob. Continue holding both buttons until you hear the door locks cycle again. This may take up to 5 minutes for a new, unprogrammed key fob. Previously programmed key fobs will usually pair much faster.
-
Program Additional Key Fobs (Optional): If you have additional key fobs (new or existing) that you want to program for your 2003 GMC Yukon, repeat step 5 for each additional key fob.
-
Exit Programming Mode: Turn the ignition key to the ON position. This action will exit the key fob programming mode.
-
Test Your Key Fobs: 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 to control the door locks.
