Whether you’re replacing a lost fob or adding an extra one, follow these instructions to program your 2004 GMC Sierra key fob quickly and efficiently.
Step-by-Step Guide to Program Your 2004 GMC Sierra Key Fob
Before you begin, make sure you have all the key fobs you intend to use with your 2004 GMC Sierra, as this procedure will erase all previously programmed remotes. You will need to program all existing and new remotes in one session.
Here’s how to program your 2004 GMC Sierra key fob:
-
Prepare the Vehicle: Begin by closing all the doors on your GMC Sierra. Insert your key into the ignition, but do not turn it on yet.
-
Initiate Programming Mode: Press and HOLD the UNLOCK button located on the driver’s side door panel. Do not release the button.
-
Cycle the Ignition: While holding the UNLOCK button, quickly turn the ignition key from the ON position to the OFF position twice. The ON position is the position just before you would start the engine, and OFF is where you can remove the key. Do this quickly – ON to OFF, then ON to OFF again.
-
Release the Unlock Button: Release the UNLOCK button on the door. You should hear the door locks cycle (lock then unlock). This lock cycling indicates that your 2004 GMC Sierra has successfully entered programming mode and is ready to pair with your key fobs.
Important Note: If the door locks cycle before you release the unlock button, the programming mode has not been activated. You will need to repeat steps 1 through 4 again, ensuring you hold the unlock button until instructed to release it after cycling the ignition.
-
Program the First Key Fob: Take the first key fob you want to program. Simultaneously press and hold both the LOCK and UNLOCK buttons on the key fob. Continue holding both buttons until you see the door locks cycle again. This may take up to 5 minutes for a new, unprogrammed remote. A previously programmed remote will usually pair much faster.
-
Program Additional Key Fobs (If Applicable): If you have more key fobs to program, repeat step 5 for each additional key fob. Make sure to program all the key fobs you want to use during this single programming session.
-
Exit Programming Mode: Turn the ignition key to the ON position. This action will exit the programming mode.
-
Test Your Key Fobs: Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly with your 2004 GMC Sierra’s remote locking system.
Troubleshooting and Tips
- Incorrect Procedure: The most common reason for programming failure is not following the steps precisely. Double-check each step and try again. Pay close attention to the timing and button presses.
- Vehicle Malfunction: If you consistently cannot enter programming mode, there might be an issue with your vehicle’s keyless entry system. In this case, consider consulting a professional automotive technician.
- New vs. Used Remotes: New, aftermarket key fobs may sometimes require a slightly longer button press during programming. Be patient and hold the buttons as instructed.
- Battery Condition: Ensure the batteries in your key fobs are fresh and have sufficient charge. Low battery power can sometimes interfere with the programming process.
By following these instructions, you should be able to easily program your 2004 GMC Sierra key fob. Enjoy the convenience of your keyless entry system once again! If you are still having trouble or prefer professional assistance, you can search for a local key fob programming service in your area.
