Lost your key fob or need to program a new remote for your 2011 Toyota Sienna? You’re in the right place. Programming your key fob yourself can save you time and money compared to dealership services. This guide provides comprehensive instructions on how to program your 2011 Toyota Sienna key fob, covering different programming modes to suit your needs. The system in your Toyota Sienna can recognize up to 4 key fobs. If you program a fifth one, it will replace the first one programmed. There are four key programming modes available for your 2011 Toyota Sienna:
- Add Mode: To register a new, unregistered key fob to your system.
- Rewrite Mode: To erase all existing key fob registrations and start the programming process from scratch.
- Confirmation Mode: To check how many key fobs are currently programmed into your system.
- Prohibit Mode: To disable all key fobs from operating the door locks.
Before starting any of the programming modes, ensure you follow these preliminary steps:
- Make sure the ignition key is not in the ignition. Ensure all doors are unlocked, and the driver’s door is open.
- Within 5 seconds, insert and remove the key from the ignition twice without turning it. Leave the key out of the ignition.
- Within 40 seconds, close and open the driver’s door twice. Leave the driver’s door in the open position.
- Insert the key into the ignition and remove it once. Leave the key out of the ignition.
- Within 40 seconds, close and open the driver’s door twice, and then close the driver’s door.
- Insert the key into the ignition and leave it in the LOCK position.
Once you have completed these steps, you can proceed with the desired programming mode.
Add Mode: Programming a New Key Fob
Add mode is used when you want to program an additional key fob to your 2011 Toyota Sienna without erasing the existing ones. Follow these steps after completing the preliminary instructions:
A1) Turn the ignition key to the “ON” position for 1 second, and then turn it back to the “LOCK” position.
A2) Remove the key from the ignition.
A3) Listen for the door locks. You should hear them “LOCK” and then “UNLOCK” after 1 second.
A4) On the key fob you are programming, press and hold both the lock and unlock buttons simultaneously for 1 to 1.5 seconds, then release them.
A5) Immediately after releasing the two buttons, press the unlock button by itself on the same key fob.
A6) Observe the response from your Sienna’s door locks:
R1) Successful Programming: The doors will “LOCK”, then “UNLOCK” once. This indicates that the key fob has been successfully programmed. If you have another key fob to program, immediately repeat steps A4 and A5 with the next key fob. Otherwise, open the driver’s door to finalize the programming.
R2) Unsuccessful or Already Programmed: The doors will “LOCK”, then “UNLOCK” twice. This response could mean a couple of things: either you didn’t use the same key fob in steps A4 and A5, or the key fob was already programmed. It could also indicate a timing issue during the button presses. Try repeating steps A4 and A5, ensuring precise timing. Keep trying until you receive the single “LOCK” then “UNLOCK” signal, indicating successful programming. If you have another key fob to program, proceed to program it as well. Once you are finished programming all key fobs, open and close the driver’s door to lock in the programming.
R3) No Response: If you hear no response from the door locks, you will need to go back to step 1 of the preliminary instructions and repeat the entire process.
Rewrite Mode: Resetting and Reprogramming Key Fobs
Rewrite mode is used to erase all previously programmed key fobs and reprogram them from the beginning. This is useful if you are unsure how many key fobs are programmed or if you want to clear all previous programming. Complete the preliminary steps first, and then follow these steps:
B1) Turn the key to the “ON” position for 1 second, then to “LOCK” for 1 second, back to “ON” for 1 second, and finally back to “LOCK” for 1 second.
B2) Remove the key from the ignition.
B3) Listen for the door locks. You should hear them cycle: “LOCK”, then “UNLOCK”, then “LOCK”, then “UNLOCK”, each separated by 1 second.
B4) On your key fob, press and hold the lock and unlock buttons simultaneously for 1 to 1.5 seconds, then release.
B5) Immediately press the unlock button by itself on the same key fob.
B6) Observe the response:
R1) Successful Rewrite & Programming: The doors will “LOCK”, then “UNLOCK” once, indicating successful programming of the key fob after rewriting the memory. If you have another key fob to program, immediately repeat from step B4. Otherwise, open the driver’s door to register the programming.
R2) Unsuccessful Programming: The doors will “LOCK”, then “UNLOCK” twice. This suggests an issue with the key fob or the timing of button presses.
R3) No Response: If there is no response, return to step 1 of the preliminary instructions and restart the process.
Confirmation Mode: Verifying Programmed Key Fobs
Confirmation mode allows you to check how many key fobs are currently programmed to your 2011 Toyota Sienna. This is a helpful way to verify if the programming was successful or to simply check the number of active remotes. After completing the initial steps, proceed as follows:
C1) Turn the ignition key to “ON” and back to “LOCK” in one-second intervals, a total of 3 times.
C2) Remove the key from the ignition.
C3) Listen to the door locks. They will “LOCK” and “UNLOCK” in 2-second intervals. Count the sets of “LOCK” and “UNLOCK”:
- 1 Set = 1 key fob programmed
- 2 Sets = 2 key fobs programmed
- 3 Sets = 3 key fobs programmed
- 4 Sets = 4 key fobs programmed
- 5 Sets = No key fobs programmed
Prohibit Mode: Disabling All Key Fobs
Prohibit mode is used to disable all programmed key fobs, preventing them from operating the door locks. This might be useful in situations where you want to ensure no remote access to your vehicle. After completing the preliminary steps:
D1) Turn the key to “ON” and back to “LOCK” in one-second intervals, a total of 5 times.
D2) Remove the key from the ignition.
D3) Listen for the door locks. You will hear them “LOCK”, then “UNLOCK” 5 times, each separated by 1 second.
D4) This action will erase all previously programmed key fobs and disable the wireless door lock function.
By following these detailed steps, you should be able to successfully program your 2011 Toyota Sienna key fob. Remember to carefully follow each step and pay attention to the timing and the responses from your vehicle’s door locks. This DIY guide aims to empower you to manage your car’s key fob programming efficiently.
