Lost your 2009 Toyota Prius key fob or need to program a new one? You’ve come to the right place. As experts at keyfobprog.com, we specialize in guiding you through automotive key programming. This comprehensive guide is specifically designed for 2009 Prius owners and will walk you through the exact steps to program your new key fob. Whether you’re dealing with a standard black logo fob or a chrome logo smart key fob, we’ve got you covered. Follow our easy-to-understand instructions to get your new key fob functioning seamlessly with your Prius.
Procedure A: Programming for Start/Stop Functionality (All Fobs)
This initial procedure is crucial for all new key fobs, whether they are black or chrome logo versions. It ensures that your new fob can start and stop your 2009 Prius engine when inserted into the key slot.
1. Initial Setup: Get inside your 2009 Prius, ensuring all doors are closed and unlocked. Make sure your car is completely turned off before proceeding.
2. Insert and Remove Existing Fob: Take your old, working key fob and insert it into the key slot, then remove it. Repeat this process four times in a row. On the fifth insertion, leave the old fob in the slot.
3. Door Cycling: Open and close the driver’s side door six times.
4. Remove Old Fob and Enter Programming Mode: Take out the old key fob from the slot. At this point, your Prius should be in key fob programming mode. You’ll notice the red anti-theft light on the dashboard remaining illuminated.
5. Program New Fob: Insert the new key fob into the slot and leave it there for a full minute. Keep an eye on the blinking red anti-theft light on the dashboard. Once it stops flashing and turns off completely, the start/stop programming for your new fob is complete.
6. Final Step for Start/Stop: Remove the new key fob from the slot. The start/stop engine function should now be programmed. If your key fob is a chrome logo version and you have Smart Key System (SKS) functionality, proceed to Procedure B. If you have a black logo fob and do not have SKS, skip to Procedure C.
Procedure B: Programming for Remote Lock/Unlock and Smart Key System (SKS) Functionality (Chrome Logo Fobs)
This procedure is specifically for chrome logo key fobs and 2009 Prius models equipped with the Smart Key System (SKS). Follow these steps to program the remote lock/unlock functions and smart key capabilities of your new fob.
1. Prepare Driver Door: Open the driver’s door and leave it open. Ensure the door is unlocked and that there is no key fob in the slot. Other doors can be either locked or unlocked. Complete the next step within 5 seconds.
2. Insert and Remove Old Fob (Twice): Take your old, working key fob and insert it into the slot, then remove it. Repeat this insertion and removal once more, for a total of two times. Complete steps 3 and 4 within 40 seconds of finishing this step.
3. Door Cycling (Twice): Close and then open the driver’s door twice.
4. Insert and Remove Old Fob (Once): Insert the old key fob into the slot and remove it one time. Complete steps 5 through 8 within 40 seconds of completing this step.
5. Door Cycling (Twice Again): Close and open the driver’s door two more times.
6. Insert Old Fob and Close Door: Insert your old key fob into the slot, and then close the driver’s door.
7. Power Button Sequence (Without Brake): Without pressing the brake pedal, press the power button. Wait for a second, press it again, wait another second, and then press it a third time to turn the car back off.
8. Remove Old Fob and Enter Add Mode: Take the old key fob out of the slot. Your Prius should now be in “add mode.” Within 3 seconds, the car should automatically lock and unlock the doors to confirm it has entered add mode. The number of lock/unlock cycles may vary slightly depending on your specific model, but it should cycle at least once. If the doors do not cycle, return to step 1 and repeat the procedure. If they do cycle, proceed to step 9.
9. Program New Fob and Test: Steps 9a through 9c should be initiated within 40 seconds of completing step 8.
9a. Hold Lock and Unlock on Old Fob: Press and hold both the Lock and Unlock buttons simultaneously on your OLD/MASTER key fob for a couple of seconds. You should see the door locks cycle once. If this doesn’t happen, it might be due to a weak CR 2032 battery in your old fob. Replace the battery and try again.
9b. Hold Lock and Unlock on New Fob: Immediately press and hold both the Lock and Unlock buttons simultaneously on your NEW key fob for about 1.5 seconds. Some users have reported needing to repeat this step twice for it to register. If it doesn’t work the first time, try executing this step twice.
9c. Press Lock on New Fob: Within three seconds of step 9b, press the Lock button on the NEW key fob. If successful, the door locks will cycle once to indicate successful programming. It may take a moment for the lock/unlock cycle to occur, so be patient. If you wait for more than a minute and there’s no cycle, proceed to step 10 and test if the SKS functions of your new fob are working.
9d. Program Additional Fobs (Optional): If you need to program another new key fob, repeat steps 9a, 9b, and 9c for each additional new fob. Once you have programmed all desired fobs, proceed to step 10.
10. Exit Programming Mode: To finalize the programming process, simply open and then close the driver’s door, or insert any key fob into the key slot.
Procedure C: Programming for Remote Lock/Unlock Functionality (Black Logo Fobs – Non-SKS)
This procedure is for black logo key fobs on 2009 Prius vehicles that are not equipped with the Smart Key System (SKS). Follow these steps to program the remote lock/unlock functions.
1. Prepare Driver Door (Non-SKS): Open the driver’s door and ensure it remains open. Make sure no key fob is in the slot and that the doors are unlocked.
2. Insert and Remove Old Fob (Twice – Non-SKS): Insert your old, working key fob into the slot and remove it. Repeat this process once more, for a total of two insertions and removals, within 5 seconds.
3. Door Cycling (Twice – Non-SKS): Close and then open the driver’s door twice.
4. Insert and Remove Old Fob (Once – Non-SKS): Insert the old key fob into the slot and remove it one time.
5. Door Cycling (Twice Again – Non-SKS): Close and open the driver’s door two more times.
6. Insert Old Fob and Close Door (Non-SKS): Insert your old key fob into the slot, and then close the driver’s door.
7. Power Button Sequence (Without Brake – Non-SKS): Without pressing the brake pedal, press the power button. Wait for a second, press it again, wait another second, and then press it a third time to turn the car back off.
8. Remove Old Fob and Enter Add Mode (Non-SKS): Remove the old key fob from the slot. Your Prius should now be in “add mode.”
9. Car Lock/Unlock Confirmation (Non-SKS): The car should automatically lock and unlock the doors twice to confirm it has entered add mode.
10. Hold Buttons on New Fob (Non-SKS): Press and hold both buttons on the new key fob simultaneously for about 1.5 seconds.
11. Press Lock Button on New Fob (Non-SKS): Within 3 seconds, press just the Lock button on the new key fob.
12. Confirmation Signal (Non-SKS): The car should respond with one quick lock/unlock cycle to verify that the new fob is successfully programmed. If the car responds with two lock/unlock cycles, it indicates that the programming was not successful. In this case, try the procedure again, ensure your fob is compatible, or check if you have too many fobs already programmed to your vehicle.
13. Exit Programming Mode (Non-SKS): To end the programming process, open and then close the driver’s door, or insert any key fob into the slot.
Important Notes
- Genuine Toyota Fobs Only: These procedures are designed for BRAND NEW key fobs purchased from a genuine Toyota dealer. Aftermarket fobs or used fobs from sources like eBay may not be compatible with full SKS functionality. For guaranteed compatibility, always source new fobs from authorized Toyota dealerships.
- Practice Makes Perfect: It’s recommended to do a “dry run” of these steps without the fobs first to familiarize yourself with the sequence, especially the timing aspects.
- Battery Condition: Ensure the battery in your old key fob is in good condition, especially when performing Procedure B. A weak battery can prevent the programming sequence from completing successfully. Consider replacing the battery in your old fob if you encounter issues.
- Part Numbers: For reference, the OEM part number for a smart access fob is 89994-47061, and for a non-smart access fob is 89070-47180. Verify compatibility with your dealer when purchasing.
By following these detailed steps, you should be able to successfully program your new 2009 Prius key fob. If you encounter any difficulties, consider revisiting each step carefully or consulting with a Toyota dealership for professional assistance.
