This guide will walk you through the entire process, ensuring you regain seamless access to your vehicle.
Before you begin, ensure you have your new, unprogrammed key fob and your Lexus RX 350 vehicle. Follow these instructions carefully to program your remote:
-
Starting Position: Make sure your Lexus RX 350 is turned off and the key is out of the ignition.
-
Driver’s Door Protocol: Open and unlock only the driver’s side door. Ensure all other doors, including the trunk or tailgate, are fully closed.
-
Key Insertion Sequence – Part 1: Within 5 seconds of step 2, insert your key into the ignition switch, and then immediately pull it out. Repeat this insert and pull out action a second time, for a total of two insertions and removals.
-
Door Cycling – Part 1: Next, close the driver’s side door, and then open it again. Repeat this close and open action once more, for a total of two close and open cycles.
-
Key Insertion Sequence – Part 2: Insert the key into the ignition one last time, and then remove it.
-
Door Cycling – Part 2: Again, close the driver’s side door, and then open it. Repeat this close and open action once more, for a total of two close and open cycles.
-
Final Key Insertion: Insert the key into the ignition switch and this time, leave it inserted. Do not remove it.
-
Door Closure: Close the driver’s side door.
-
Ignition Cycle: With the key in the ignition and the driver’s door closed, switch the ignition to the ON position, and then immediately switch it back to the OFF position.
-
Key Removal (Final): Remove the key from the ignition switch.
-
Confirmation Signal: At this point, you should observe the door locks cycling (locking and unlocking). This indicates that your 2009 Lexus RX 350 has successfully entered key fob programming mode.
-
Remote Programming – First Remote: Take your first key fob remote that you wish to program. Press and hold both the LOCK and UNLOCK buttons simultaneously for about 1.5 seconds. After releasing these two buttons, immediately press and hold only the LOCK button for approximately 2 seconds.
-
Programming Confirmation: The door locks should cycle once more to confirm that the remote has been successfully programmed. If you have additional key fobs to program, repeat step 12 for each additional remote. If you are finished programming remotes, proceed to the next step.
-
Exit Programming Mode: Open the driver’s side door. This action completes the key fob programming sequence, and your new 2009 Lexus RX 350 key fob should now be fully functional.
