Step-by-Step Guide to Program Your 2007 Trailblazer Key Fob
Before you begin, ensure you have your key and the new key fob for your 2007 Chevy Trailblazer. Follow these programming steps carefully:
-
Ensure Vehicle Readiness: Begin by closing all the doors of your Chevrolet Trailblazer. This is crucial for the programming sequence to initiate correctly.
-
Ignition Key Insertion: Insert your ignition key into the ignition cylinder of your Trailblazer.
-
Initiate Unlock Button Hold: Locate the power UNLOCK button on the driver’s side door panel. Press and hold down this button. Maintain pressure on the unlock button, do not release it until instructed in step 9.
-
Rapid Ignition Sequence Preparation: The next steps (5 through 8) need to be performed in quick succession. Get ready to move swiftly.
-
Ignition ON (First Time): Turn the ignition key to the ON position. This is the position right before starting the engine – where the dashboard lights illuminate.
-
Ignition OFF: Turn the ignition key back to the OFF position.
-
Ignition ON (Second Time): Again, turn the ignition key to the ON position (dashboard lights on).
-
Ignition OFF (Second Time): Turn the ignition key back to the OFF position for the final time in this sequence.
-
Release Unlock Button & Await Lock Cycle: Now, release the power UNLOCK button that you have been holding down. If the programming mode has been successfully entered, your Chevrolet Trailblazer should respond by automatically cycling the door locks – locking and then unlocking. Important: If the locks do not cycle automatically after you release the button, the vehicle has not entered programming mode. In this case, remove the key from the ignition, open the driver’s side door, and return to step 1 to restart the procedure. If the locks cycle correctly, proceed to the next step.
-
Key Fob Programming Activation: Take your 2007 trailblazer key fob remote. Simultaneously press and hold down both the LOCK and UNLOCK buttons on the fob. Continue holding both buttons until you observe the doors lock and unlock again. This step might take up to 30 seconds, so be patient and keep holding the buttons.
-
Program Additional Remotes (If Necessary): 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 intend to use in this session.
-
Exit Programming Mode: To finalize the programming and exit the programming mode, turn the ignition key to the ON position one last time.
-
Functionality Test: Remove the key from the ignition and test all the buttons on each programmed 2007 trailblazer key fob to ensure they are working correctly – locking, unlocking, and any other functions your fob may have.
If you followed these steps correctly, your new 2007 trailblazer key fob should now be successfully programmed to your vehicle.
