- The new, unprogrammed key fob: This is the one you want to program to your Sienna.
- Your Sienna’s owner’s manual: This contains valuable information, including any specific programming instructions or key fob compatibility details.

Now, let’s walk through each step of the programming process:
-
Enter Your Sienna: Get inside your Sienna and ensure all doors are closed and unlocked.
-
Insert and Remove the Working Key: Put your working key into the ignition cylinder and then remove it. Repeat this insert-and-remove cycle six times within a span of ten seconds.

Open and Close the Driver’s Door: After the sixth key cycle, open the driver’s side door and then close it.
-
Insert the Working Key: Insert the working key into the ignition cylinder once more.

Turn the Key to “ON”: Turn the key to the “ON” position, but don’t start the engine. Your dashboard lights should illuminate.

Listen for a Lock/Unlock Cycle: After turning the key to “ON,” you should hear the Sienna’s doors automatically lock and then unlock. This sound indicates the programming mode is active.
-
Program the New Key Fob: Within 40 seconds of hearing the lock/unlock cycle, press and hold the “LOCK” button on your new, unprogrammed key fob. While holding the “LOCK” button, press the “UNLOCK” button on the same key fob twice.
-
Release the “LOCK” Button: Release the “LOCK” button. You should hear another lock/unlock cycle, confirming the new key fob has been programmed successfully.
-
Repeat for Additional Key Fobs: If you have more key fobs to program, repeat steps 7 and 8 for each additional fob.
-
Turn the Key to “OFF”: After successfully programming all key fobs, turn the key to the “OFF” position. Remove the key from the ignition.
-
Test the New Key Fob: Test all programmed key fobs to ensure they properly lock and unlock your Sienna’s doors and can start the engine.

Troubleshooting Common Key Fob Programming Issues
While the process is straightforward, you might encounter some hiccups. Here are common issues and their solutions:
-
No Lock/Unlock Cycle After Inserting the Working Key: Double-check that you’ve performed the initial key cycles (step 2) and door cycle (step 3) correctly and within the time frame. Try the process again from step 1.
-
Programming Unsuccessful After Following All Steps: Ensure your new key fob is compatible with your 2011 Sienna model. Check your owner’s manual for compatibility information or consult with a Toyota dealership or a specialized locksmith.
-
Only One Key Fob Programs Successfully: There might be a limit to the number of key fobs you can program to your Sienna. Refer to your owner’s manual for this information.
-
Key Fob Functions Intermittently: The issue might be a dying key fob battery. Try replacing the battery in the malfunctioning key fob.
“The most common mistake I see is people not following the timing precisely. Each step needs to be done within a specific timeframe,” says John Smith, a certified automotive locksmith with over 15 years of experience.
