Is your 2005 Gmc Sierra Key Fob no longer working, or did you recently purchase a replacement remote? Luckily, programming your key fob for your 2005 GMC Sierra is a straightforward process you can complete yourself at home. This guide will provide you with easy-to-follow instructions to get your key fob working again in minutes.
Before you begin, ensure you have all the necessary key fobs you wish to program for your vehicle, including any existing remotes. This procedure will program all remotes at once.
Here’s how to program your 2005 GMC Sierra key fob:
-
Ensure all doors are completely closed. This is crucial for the programming sequence to initiate correctly.
-
Insert your key into the ignition cylinder. Do not turn the key yet.
-
Press and HOLD the power UNLOCK button located on the driver’s side door panel. Keep holding this button down throughout steps 4 through 9.
-
Perform the following steps in rapid succession:
-
Turn the ignition key to the ON position. This is the position right before starting the engine.
-
Turn the ignition key back to the OFF position.
-
Turn the ignition key to the ON position again.
-
Turn the ignition key back to the OFF position once more.
-
Release the power UNLOCK button. If you have successfully entered programming mode, you will hear the door locks cycle, locking and then unlocking automatically. This indicates the vehicle is ready to learn the new key fob codes. If the locks do not cycle, you will need to repeat steps 1-9. Ensure you hold the unlock button until instructed to release it and that you perform steps 5-8 quickly.
-
Immediately take your first key fob remote and press and HOLD both the LOCK and UNLOCK buttons simultaneously. Continue holding both buttons until you hear the door locks cycle again. This may take up to 30 seconds. This step programs the first remote.
-
Repeat step 10 for each additional key fob remote you wish to program, including any existing remotes that were working previously. It is important to program all remotes you want to use in this session.
-
Turn the ignition key to the ON position one last time. This action will exit the key fob programming mode.
-
Test each of your programmed key fobs to ensure they are working correctly by pressing the LOCK and UNLOCK buttons.
By following these steps, you should have successfully programmed your 2005 GMC Sierra key fob. If you encounter difficulties or prefer professional assistance, you can search for a local key fob programming service in your area.
