Are you looking to program a new or existing key fob for your 2004 GMC Yukon? Perhaps you’ve purchased a replacement key fob or need to reprogram your current one. This guide provides straightforward, step-by-step instructions to program your 2004 Yukon Key Fob yourself, saving you time and potential dealership costs. Before you begin, ensure you have all the key fobs you intend to use with your vehicle, as this process will erase all previously programmed remotes.
Programming Your 2004 Yukon Key Fob: A Simple Process
Follow these instructions carefully to successfully program your 2004 Yukon key fob:
-
Preparation is Key: Begin by closing all the doors of your 2004 GMC Yukon. 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 this UNLOCK button. Do not release it until instructed in step 4.
-
Ignition Cycling: While holding the UNLOCK button, quickly switch the ignition from the OFF position to the ON position, and then back to OFF, twice in rapid succession. Remember, the “ON” position is just before starting the engine, where the dashboard lights illuminate.
-
Release and Confirm: Now, RELEASE the UNLOCK button. If you have successfully entered programming mode, the door locks will cycle – locking and then unlocking. This lock cycling is your confirmation that the vehicle is ready to learn the new key fob programming.
Important Note: If the door locks cycle before you release the UNLOCK button, the programming mode has not been correctly initiated. You will need to repeat the process from step one. If the locks continue to cycle prematurely, double-check that you are following each step precisely or there might be an issue with your vehicle’s keyless entry system.
-
Pairing the First Key Fob: Take the first 2004 Yukon key fob you wish to program. Simultaneously press and hold both the LOCK and UNLOCK buttons on the key fob. Continue holding these buttons until the vehicle responds again by cycling the door locks. This may take a few moments, especially when programming a new, unprogrammed remote. A previously paired remote will typically program more quickly.
-
Programming Additional Key Fobs: If you have more 2004 Yukon key fobs to program (including existing ones you want to continue using), repeat step 5 immediately for each additional key fob.
-
Exit Programming Mode: Once you have programmed all desired key fobs, turn the ignition key to the ON position. This action will exit the programming mode.
-
Test Your Remotes: Programming is now complete. Remove the key from the ignition and test each of your programmed 2004 Yukon key fobs to ensure they are working correctly by locking and unlocking the doors and activating other remote functions.
