- Your 2000 GMC Sierra vehicle
- All key fobs you wish to program (both new and existing)
- Your vehicle key
Step-by-Step Programming Instructions for Your 2000 GMC Sierra Key Fob
Follow these steps carefully to successfully program your 2000 GMC Sierra key fob:
-
Ensure All Doors Are Closed: Begin by making sure all doors of your 2000 GMC Sierra are completely closed. This is crucial for the system to enter programming mode correctly.
-
Insert the Key into the Ignition: Place your key into the ignition cylinder.
-
Press and Hold the UNLOCK Button: Locate the power UNLOCK button on the driver’s side door panel. Press and hold this button down. Do not release it until instructed in a later step.
-
Cycle the Ignition: While holding the UNLOCK button, you need to quickly turn the ignition from OFF to ON and back to OFF twice. “ON” is the position just before you would start the engine, and “OFF” is the position where you can remove the key. So, the sequence is: ON, OFF, ON, OFF.
-
Release the UNLOCK Button: After cycling the ignition as described, release the power UNLOCK button on the driver’s side door panel.
-
Confirm Programming Mode: Upon releasing the UNLOCK button, your 2000 GMC Sierra should automatically lock and unlock its doors. This lock and unlock cycle is your confirmation that the vehicle has successfully entered programming mode and is ready to learn the new key fob signals.
- Troubleshooting Tip: If the door locks cycle before you release the UNLOCK button, it means the vehicle has not entered programming mode. You will need to start over from Step 1. Remove the key, open the door, and begin again.
- Further Troubleshooting: If the vehicle continues to lock and unlock prematurely, there might be an issue with your GMC Sierra’s keyless entry system. In this case, it is recommended to seek assistance from a certified automotive professional.
- Timing is Key: If you are unable to get the door locks to cycle at all after releasing the unlock button, you may be turning the ignition key too quickly or too slowly. Try adjusting your speed and repeat from Step 1.
-
Program the First Key Fob: Take the first key fob you wish to program. Press and hold both the LOCK and UNLOCK buttons on the remote simultaneously. Keep holding them until you observe the door locks cycle again. This might take up to 30 seconds. The door lock cycle indicates that the vehicle has recognized and programmed this key fob.
-
Program Additional Key Fobs: If you have more key fobs to program, repeat Step 7 for each additional remote.
-
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.
-
Final Steps and Testing: Turn the ignition key to the OFF position and remove the key from the ignition. Now, test each of your programmed key fobs to ensure they are working correctly. Try locking, unlocking, and activating any other functions your key fob may have, such as the panic button.
Congratulations! You have successfully programmed your 2000 GMC Sierra key fob.
