Lost your key fob or need to program a new one for your 2000 GMC Sierra? Don’t worry, programming your key fob is a straightforward process you can accomplish right at home without needing a dealership or professional service. This guide will walk you through each step to get your 2000 GMC Sierra key fob programmed quickly and easily.
Before you begin, ensure you have your replacement key fob. If you need a new one, you can order a compatible Key Fob from Keylessentryremotefob.com. Let’s get started with the programming procedure.
Step-by-Step Programming Instructions
-
Start by Closing All Doors: Make sure all doors of your 2000 GMC Sierra are completely closed before beginning the programming sequence. This ensures proper communication with the vehicle’s system.
-
Insert the Ignition Key: Place your key into the ignition cylinder. You will be using the ignition to cycle through different modes to initiate programming.
-
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 button until instructed to release it later in the process.
-
Ignition Cycling Sequence (Fast Steps): The next four steps (5 through 8) need to be performed in rapid succession. Be prepared to move quickly between turning the ignition ON and OFF.
-
Turn Ignition to ON Position: Turn the ignition key to the ON position. This is the position just before you would crank the engine to start. The dashboard lights should illuminate.
-
Turn Ignition to OFF Position: Immediately after turning to the ON position, turn the ignition key back to the OFF position. Do not remove the key, simply turn it back.
-
Turn Ignition to ON Position Again: Once more, quickly turn the ignition key to the ON position, just like in step 5.
-
Turn Ignition to OFF Position Again: Finally, and again quickly, turn the ignition key back to the OFF position.
-
Release the UNLOCK Button: Now, release the power UNLOCK button that you have been holding down since step 3. At this point, your 2000 GMC Sierra should automatically cycle the door locks, locking and then unlocking. This indicates that the vehicle has successfully entered programming mode.
- Troubleshooting: If the door locks do not cycle automatically 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 from the beginning. Ensure you are performing steps 5 through 8 quickly.
-
Program the Key Fob(s): 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 (lock and unlock). This may take up to 30 seconds. The lock cycle confirms that the key fob has been successfully programmed.
-
Program Additional Remotes (If Applicable): If you have additional key fobs to program, including any existing remotes you want to continue using, repeat step 10 immediately for each additional remote. It’s important to program all remotes you want to use during this programming session.
-
Exit Programming Mode: Turn the ignition key to the ON position one last time. This action will exit the programming mode.
-
Test Your Remotes: Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly. Press the LOCK and UNLOCK buttons to verify proper operation.
