Lost your key fob or need to program a new one for your 2001 GMC Sierra? Don’t worry, programming your key fob yourself is easier than you might think and can save you a trip to the dealership. This guide provides simple, step-by-step instructions to program your 2001 GMC Sierra key fob quickly and efficiently.
Step-by-Step Programming Instructions
Before you begin, ensure all doors of your 2001 GMC Sierra are closed. This is crucial for the programming sequence to work correctly. Follow these steps carefully:
-
Insert Your Key: Place the ignition key into the ignition cylinder of your GMC Sierra.
-
Press and Hold Unlock: 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.
-
Ignition Cycle – ON Position (1st time): While holding the UNLOCK button, turn the ignition key to the ON position. This is the position just before starting the engine – where the dashboard lights illuminate.
-
Ignition Cycle – OFF Position: Immediately turn the ignition key back to the OFF position.
-
Ignition Cycle – ON Position (2nd time): Quickly turn the ignition key back to the ON position again, keeping the UNLOCK button pressed.
-
Ignition Cycle – OFF Position: Turn the ignition key back to the OFF position for the final time in this sequence, still holding the UNLOCK button.
-
Release Unlock Button & Listen for the Locks: Release the power UNLOCK button on the driver’s door. At this point, your GMC Sierra should automatically cycle the door locks – you should hear them lock and then unlock. This lock cycling indicates that your vehicle has successfully entered programming mode.
- Troubleshooting: If you do not hear the locks cycle after releasing 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 more quickly and precisely.
-
Program Your Key Fob: Take the key fob you wish to program. Simultaneously press and hold down both the LOCK and UNLOCK buttons 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 2001 GMC Sierra.
-
Program Additional Key Fobs (Optional): If you have additional key fobs to program (including any existing remotes you want to ensure still work), repeat step 10 immediately for each additional key fob.
-
Exit Programming Mode: Turn the ignition key to the ON position one last time. This action will exit the key fob programming mode.
-
Test Your Key Fobs: Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly by pressing the LOCK and UNLOCK buttons and verifying the doors respond as expected.
