Lost your key fob or need to program a new one for your 2005 GMC Sierra? You’re in the right place. Programming your key fob yourself can save you time and money compared to dealership services. This guide provides straightforward, easy-to-follow instructions to get your 2005 GMC Sierra key fob programmed and working in no time.
Step-by-Step Guide to Program Your 2005 GMC Sierra Key Fob
Follow these steps carefully to successfully program your 2005 GMC Sierra key fob:
-
Ensure all doors of your GMC Sierra are completely closed. This is crucial for the programming sequence to initiate correctly.
-
Insert your ignition key into the ignition cylinder.
-
Locate the power UNLOCK button on the driver’s side door panel. Press and hold down this button. Maintain pressure on the unlock button until step 9 instructs you to release it.
-
The next steps (5 through 8) need to be performed in quick succession. Be prepared to execute them rapidly.
-
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 the ignition key back to the OFF position.
-
Again, turn the ignition key to the ON position.
-
Turn the ignition key back to the OFF position one more time.
-
Release the power UNLOCK button on the driver’s door panel. At this point, your GMC Sierra should automatically respond by cycling the door locks – locking and then unlocking. This indicates that the vehicle has successfully entered key fob programming mode. If the door locks do not cycle, remove the key from the ignition, open and close the driver’s side door, and restart the procedure from step 1.
-
Take your key fob remote. Press and hold down both the LOCK and UNLOCK buttons simultaneously on the remote. Continue holding both buttons until you hear the doors lock and unlock again. This process might take up to 30 seconds.
-
If you have additional key fobs to program (including any existing remotes you wish to continue using), repeat step 10 immediately for each additional remote. It’s important to program all remotes you intend to use in one programming session.
-
To exit the key fob programming mode, turn the ignition key to the ON position once more.
-
Remove the key from the ignition and test each of your programmed key fobs to ensure they are working correctly by pressing the lock and unlock buttons.
If you encounter difficulties programming your key fob, or if you prefer professional assistance, you can search for a qualified key fob installer in your local area using online search engines. Many automotive locksmiths or car audio shops offer key fob programming services.
