Is your 2002 GMC Yukon key fob malfunctioning, or did you get a new replacement remote? Programming your key fob yourself can save you time and money compared to dealership services. This guide provides straightforward, step-by-step instructions to program your 2002 GMC Yukon key fob quickly and easily at home.
Step-by-Step Guide to Program Your 2002 GMC Yukon Key Fob
Follow these instructions carefully to successfully program your 2002 GMC Yukon key fob:
-
Prepare Your Vehicle: Ensure all doors of your 2002 GMC Yukon are fully closed. Insert your key into the ignition, but do not turn it on 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 instructed in step 4.
-
Cycle Ignition: 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 just before you would start the engine, and “OFF” is where you can remove the key. Do not start the engine.
-
Release Unlock Button and Wait for Confirmation: Release the UNLOCK button. You should hear the door locks cycle (lock then unlock). This lock cycling indicates that your 2002 GMC Yukon 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 steps 1 through 4 again, ensuring you follow the timing precisely. If the locks continue to cycle prematurely, double-check that you are following the procedure correctly. If issues persist, there might be a malfunction in your vehicle’s keyless entry system.
-
Program Your Key Fob: Take the first key fob you wish to program (or reprogram). Simultaneously press and hold both the LOCK and UNLOCK buttons on the key fob. Continue holding both buttons until the vehicle responds by cycling the door locks again.
- New Remotes: Programming a new, previously unpaired remote may take longer, potentially up to 5 minutes of holding the buttons. Be patient and continue holding.
- Existing Remotes: Reprogramming a remote that was previously paired to your Yukon will usually be much faster.
-
Program Additional Remotes (Optional): If you have additional key fobs (new or existing) that you want to program for your 2002 GMC Yukon, repeat step 5 for each additional remote.
-
Exit Programming Mode: Turn the ignition key to the ON position one last time. This action will exit the key fob programming mode.
-
Test Your Remotes: Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly with your 2002 GMC Yukon. Test all buttons: LOCK, UNLOCK, and any other functions your key fob may have.
