Lost your key fob or need to program a new one for your 2006 GMC Sierra? You can easily program a new key fob yourself right at home without the need for a dealership or locksmith. This guide provides clear, easy-to-follow instructions to get your 2006 GMC Sierra key fob programmed and working in no time.
Step-by-Step Programming Guide for Your 2006 GMC Sierra Key Fob
Before you begin, make sure you have all the key fobs you intend to use with your vehicle. This programming procedure will erase all previously programmed key fobs, so you must program all existing and new remotes during this process.
Step 1: Prepare Your Vehicle
Ensure all doors of your 2006 GMC Sierra are fully closed. Insert your key into the ignition, but do not turn it on yet.
Step 2: Initiate Programming Mode
Press and HOLD the UNLOCK button located on the driver’s side door panel. Do not release the button until instructed in step 4.
Step 3: Cycle the Ignition
While holding the UNLOCK button, quickly turn the ignition key from the OFF position to the ON position, and then back to OFF, twice in rapid succession. “ON” is the position right before you would start the engine, and “OFF” is the position where you can remove the key.
Step 4: Release the Unlock Button
Release the UNLOCK button on the door. If you have successfully entered programming mode, the door locks will cycle from locked to unlocked automatically. This lock cycling indicates that your 2006 GMC Sierra is now ready to learn the new key fob.
Important Note: If the door locks cycle before you release the UNLOCK button, the programming mode has not been successfully entered. You will need to repeat steps 1 through 4 again, ensuring you follow each step precisely. If the locks continue to cycle prematurely, double-check that you are following the procedure correctly, or there might be an issue with your vehicle’s keyless entry system.
Step 5: Program Your Key Fob(s)
Take the first key fob you want to program. Simultaneously press and hold both the LOCK and UNLOCK buttons on the key fob. Continue holding both buttons until the vehicle responds again by cycling the door locks. This might take up to 5 minutes when programming a brand new, unprogrammed key fob. A key fob that has been previously paired to the vehicle will typically program much faster.
Repeat step 5 for each additional key fob you wish to program, including any existing remotes you want to continue using.
Step 6: Exit Programming Mode
Turn the ignition key to the ON position and leave it there. This action will exit the key fob programming mode. Programming is now complete.
Step 7: Test Your Key Fobs
Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly with your 2006 GMC Sierra.
If you encounter any difficulties programming your key fob, or prefer to have a professional handle the programming for you, you can search for a qualified key fob installer in your local area.
