Programming Your 2007 Toyota Sienna Key Fob
This process should be followed carefully to ensure successful programming. Make sure you are inside or very close to your 2007 Toyota Sienna during these steps.
-
Start with Key and Door Status: Begin by removing the key from the ignition. Ensure that the driver’s side door is open and unlocked. Crucially, make sure all other doors, including the trunk or liftgate, are completely closed.
-
Ignition Key Insertion Sequence (Part 1): Within a 5-second window, insert your key into the ignition switch and then immediately pull it out. Repeat this insert and pull out action a second time.
-
Door Open/Close Cycle (Part 1): Next, close the driver’s side door, and then open it again. Repeat this close and open cycle one more time.
-
Ignition Key Insertion Sequence (Part 2): Insert the key into the ignition switch once more, and then remove it again.
-
Door Open/Close Cycle (Part 2): Close the driver’s side door, and then open it again. Repeat this close and open cycle one more time.
-
Final Key Insertion into Ignition: Insert the key into the ignition switch and this time, leave it in the ignition.
-
Close Driver’s Door: Close the driver’s side door.
-
Ignition ON/OFF Cycle: Turn the ignition switch to the ‘ON’ position, and then immediately turn it back to the ‘OFF’ position. Do not start the engine.
-
Remove Key from Ignition: Take the key out of the ignition switch.
-
Lock Cycle Confirmation: At this point, you should observe the door locks cycling (locking and unlocking automatically). This lock cycle indicates that your 2007 Toyota Sienna has successfully entered programming mode and is ready to accept the new key fob signal.
-
Programming the Key Fob: 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 again. This lock cycle confirms that the remote has been successfully programmed to your 2007 Toyota Sienna. If you have additional key fobs to program, repeat step 12 for each additional remote. If you are finished programming all your key fobs, proceed to the next step.
-
Exit Programming Mode: Open the driver’s side door. This action signals the system to exit the key fob programming mode.
Your 2007 Toyota Sienna Key Fob Programming is now complete! Test each of your programmed key fobs to ensure they are working correctly by locking and unlocking your doors, and activating the panic alarm if your fob is equipped with one.
Troubleshooting and Tips
If you encounter issues during the programming process, consider the following:
- Timing is Crucial: Ensure you are performing the steps within the specified timeframes, especially the 5-second window in the initial steps.
- Door and Ignition Accuracy: Double-check that you are opening and closing only the driver’s side door as instructed, and that your key insertions and removals from the ignition are precise.
- Battery Condition: Ensure the battery in your new key fob is new and fully charged. A low battery can sometimes interfere with the programming process.
- Correct Key Fob: Verify that the part number on your new key fob is indeed GQ43VT20T and that it is compatible with a 2007 Toyota Sienna.
- Repeat the Process: If the programming is unsuccessful on the first try, carefully repeat all the steps from the beginning. It sometimes takes a couple of attempts to get the timing and sequence just right.
