Lost your 2002 GMC Sierra key fob or need to program a new one? Don’t worry, programming your key fob for your 2002 GMC Sierra can be a straightforward process you can do yourself, saving you time and money compared to dealership programming. This guide provides you with clear, step-by-step instructions to program your 2002 GMC Sierra key fob quickly and efficiently.
Step-by-Step Programming Instructions for Your 2002 GMC Sierra Key Fob
Before you begin, ensure you have your new, unprogrammed key fob and that your 2002 GMC Sierra is readily accessible. Follow these steps carefully to successfully program your remote:
-
Ensure All Doors Are Closed: Begin by making sure all doors of your 2002 GMC Sierra, including the tailgate or rear window if applicable, are completely closed. This is crucial for the programming sequence to initiate correctly.
-
Insert the Key into the Ignition: Place your ignition key into the ignition cylinder. Do not turn the key yet.
-
Press and Hold the UNLOCK Button: Locate the power UNLOCK button on the driver’s side door panel. Press and hold this button down. Maintain pressure on the UNLOCK button throughout the next several steps until step 9 instructs you to release it.
-
Rapid Ignition Key Cycling (Steps 5-8): Perform the following steps in quick succession. Timing is important for the vehicle to enter programming mode.
-
Turn Ignition to the ON Position: With the UNLOCK button still held down, turn the ignition key to the “ON” position. This is the position just before you would engage the starter to crank the engine. The dashboard lights should illuminate.
-
Turn Ignition to the OFF Position: Immediately after turning the ignition to “ON”, turn the key back to the “OFF” position. Do not remove the key from the ignition.
-
Turn Ignition to the ON Position Again: Repeat step 5, turning the ignition key back to the “ON” position.
-
Turn Ignition to the OFF Position Again: Repeat step 6, turning the ignition key back to the “OFF” position for the second time.
-
Release the UNLOCK Button: Now, release the power UNLOCK button on the driver’s door panel.
-
Listen for the Door Locks to Cycle: Upon releasing the UNLOCK button, the vehicle should automatically respond by cycling the door locks – you should hear them lock and then unlock. This lock cycling is your confirmation that the vehicle has successfully entered key fob programming mode.
- Troubleshooting: If the door locks do not cycle automatically after you release the unlock button, the vehicle has not entered programming mode. If this happens, remove the key from the ignition, open the driver’s side door, and return to step 1 to repeat the procedure from the beginning, ensuring you perform steps 5 through 8 quickly and smoothly.
-
Program the Key Fob(s): Immediately after the door locks cycle, take the key fob you wish to program. Press and hold down both the LOCK and UNLOCK buttons simultaneously on the key fob. Continue holding both buttons until you hear the door locks cycle again. This may take up to 30 seconds. The lock cycle confirms that the key fob has been successfully programmed to your 2002 GMC Sierra.
-
Program Additional Remotes (If Applicable): If you have additional key fobs to program (including any existing remotes you want to continue using), repeat step 11 immediately for each additional remote. It’s important to program all remotes you want to use during this programming session.
-
Exit Programming Mode: To finalize the programming process and exit programming mode, turn the ignition key to the “ON” position one last time.
-
Test the Key Fob(s): Remove the key from the ignition and test each of your newly programmed key fobs to ensure they are working correctly. Test all buttons – LOCK, UNLOCK, and any other functions like panic or trunk release if your fob has them – to confirm proper operation.
