Step-by-Step Guide to Program Your Toyota Sienna Key Fob
Before you begin, ensure you have your new, compatible Toyota Sienna key fob and that your Sienna is in a suitable location for programming. Follow these steps carefully:
-
Initial Setup: Make sure your key is removed from the ignition. Open and unlock only the driver’s side door. It’s crucial that all other doors, including the trunk or tailgate, are completely closed throughout this process.
-
Key Insertion: Insert your key into the ignition switch, and then immediately pull it back out. Do not turn the ignition on at this stage.
-
Locate Door Lock Switch: Identify the power door lock/unlock switch located on the driver’s side door panel.
-
Lock/Unlock Cycle (5 Times): Perform the LOCK and UNLOCK action using the door switch five times in quick succession. Aim for approximately one second per complete LOCK and UNLOCK cycle. This means a full lock and unlock counts as one cycle within that second.
-
Driver’s Door Action: Close the driver’s side door and then immediately open it again.
-
Lock/Unlock Cycle (5 Times Again): Repeat the LOCK and UNLOCK action with the door switch another five times, again aiming for one cycle per second. Remember, you have a 50-second window to complete the next few steps, so be prepared to move swiftly but accurately.
-
Key Insertion and Ignition Cycle: Insert the key back into the ignition.
-
Ignition ON/OFF (Twice): Turn the ignition to the “ON” position (just before starting the engine) and then immediately turn it back to the “OFF” position. Repeat this ON and OFF cycle a second time.
-
Key Removal: Take the key out of the ignition.
-
Confirmation – Door Lock Cycle: At this point, if you’ve successfully entered programming mode, the door locks should automatically cycle – you’ll hear them lock and then unlock. This confirms the system is ready to learn the new key fob.
-
Remote Button Press (Simultaneous): Take your first key fob that you wish to program. Press and release both the LOCK and UNLOCK buttons on the remote at the exact same time.
-
Lock Button Hold: Immediately after releasing both buttons, press and HOLD ONLY the LOCK button on the same remote for about two seconds.
-
Confirmation – Door Lock Cycle (Again): The door locks should cycle once more (lock and unlock) to indicate that the remote has been successfully programmed into the system.
-
Programming Additional Remotes (Optional): If you have more key fobs to program, repeat steps 12 and 13 for each additional remote. If you are done programming all your remotes, proceed to the final step.
-
Final Step – Door Closure: Close the driver’s side door. This action finalizes the programming sequence. Your Toyota Sienna Key Fob Replacement programming should now be complete.
This DIY method provides a convenient way to program your Toyota Sienna key fob, potentially saving time and money. Always ensure you are using a compatible key fob for your vehicle model and year. If you encounter issues or the programming is unsuccessful, consulting your Toyota Sienna owner’s manual or contacting a professional locksmith or dealership for assistance is recommended.
