Is your 2005 Gmc Yukon Key Fob malfunctioning, or did you recently get a replacement and need to program it? You’re in luck! Programming your key fob for your 2005 GMC Yukon can often be done right at home without any special tools. This guide provides you with easy-to-follow, step-by-step instructions to get your key fob working again.
Step-by-Step Programming Instructions for Your 2005 GMC Yukon Key Fob
Before you begin, ensure you have all the key fobs you intend to use with your 2005 GMC Yukon, including any currently working ones. This procedure requires programming all remotes at the same time.
-
Start by Closing All Doors: Make sure all doors of your GMC Yukon are completely closed. This is crucial for the programming sequence to initiate 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.
-
Ignition Cycling: While holding the UNLOCK button, quickly turn the ignition key to the ON position (just before starting the engine) and then back to the OFF position. Repeat this sequence once more, so it’s ON, OFF, ON, OFF in quick succession.
-
Release the UNLOCK Button and Listen for the Lock Cycle: Let go of the power UNLOCK button on the driver’s side door. At this point, your 2005 GMC Yukon should automatically lock and unlock its doors. This automatic lock and unlock cycle indicates that the vehicle has successfully entered programming mode.
- Troubleshooting Tip: If the door locks cycle before you release the unlock button, the vehicle has not entered programming mode. If this happens, remove the key, open the driver’s side door, and go back to step 1 to restart the process. If the issue persists, there might be a problem with your vehicle’s system, and you may need professional programming.
- Another Tip: If the door locks don’t cycle at all after releasing the button, double-check that you are turning the key quickly enough, or if there might be an issue with your vehicle’s keyless entry system. It’s also possible that your Yukon isn’t equipped with a factory keyless entry system.
-
Program the First Key Fob: Immediately after the doors cycle, take the first key fob you want to program. Press and hold both the LOCK and UNLOCK buttons on the fob simultaneously. Keep holding them until the door locks cycle once again. This might take up to 30 seconds. The lock cycle confirms that the key fob has been successfully programmed.
-
Program Additional Key Fobs: If you have more key fobs to program (including your original working fobs), repeat step 6 for each additional key fob.
-
Exit Programming Mode: Once you have programmed all desired key fobs, turn the ignition key to the ON position one last time. This action will exit the programming mode.
-
Test Your Key Fobs: Turn the ignition OFF, remove the key from the ignition, and test all of your programmed key fobs to ensure they are working correctly by pressing the LOCK and UNLOCK buttons.
