Understanding Your 2002 GMC Sierra Key Fob
Before we dive into the programming process, it’s helpful to understand the type of key fob your 2002 GMC Sierra uses. This model year typically utilizes a simple system with a few buttons for locking and unlocking the doors and may include a panic button.
Knowing the specific functions of your key fob will help you confirm that it’s working correctly after programming.
What You’ll Need to Program Your Key Fob
Gather the following items before you begin:
- All existing key fobs: You’ll need to program all your fobs in one session, as the process erases any previously stored fobs.
- Working key: You’ll need a working key to start the programming sequence.
Step-by-Step Guide to Program Your Key Fob
Follow these steps carefully to program your 2002 GMC Sierra key fob:
- Enter programming mode: Close all doors and insert your working key into the ignition. Turn the key from the “Off” position to the “Run” position (where your dashboard lights up) three times, ending in the “Run” position.
- Watch for confirmation: The door locks should cycle (lock and unlock) once to indicate that the vehicle has entered programming mode.
- Press and hold the lock button: On the first key fob you want to program, press and hold the lock button.
- Press and release the unlock button: While still holding the lock button, press and release the unlock button.
- Release the lock button: Release the lock button. The door locks should cycle again to confirm that the fob has been programmed.
- Repeat for additional fobs: Repeat steps 3-5 for any other key fobs you want to program, including spares.
- Exit programming mode: Turn the key to the “Off” position.

Troubleshooting Tips
If you encounter any issues during programming, consider the following:
- Battery Check: Ensure the battery in your key fob is fresh and properly installed. A weak battery can interfere with the programming process.
- Timing is Key: The timing of the ignition key turns and button presses is crucial. If it doesn’t work the first time, try again, being mindful of a steady pace.
- Distance Matters: Keep the key fob close to the ignition during programming to ensure a strong signal.
- Programming Limit: The 2002 GMC Sierra typically has a limit on the number of fobs it can store. Consult your owner’s manual for this information.
