Programming a new key fob for your 2007 Toyota Prius can seem daunting, but it’s absolutely achievable at home with the right instructions. This comprehensive guide will walk you through the complete process, ensuring you can program your new key fob quickly and efficiently. Whether you need to program a standard start/stop function or advanced Smart Key System (SKS) features, we’ve got you covered.
This guide is specifically designed for brand new key fobs purchased from a genuine Toyota dealer. It’s important to note that aftermarket fobs or those from unauthorized sources like eBay (unless sold by a genuine dealer’s eBay store) may not be compatible with the full functionality of your Prius, especially the Smart Key System.
Let’s dive into the programming procedures. We’ve broken it down into three clear methods based on your key fob type and Prius features:
Procedure A: Programming the Basic Start/Stop Function (For All 2007 Prius Key Fobs)
This procedure is essential for all new key fobs, regardless of whether they have a black or chrome logo or support the Smart Key System. It programs the fundamental start/stop engine function when the fob is inserted into the key slot.
1. Initial Setup:
- Get into your 2007 Prius, ensuring all doors are closed and unlocked.
- Confirm the car is completely turned off.
2. Insert and Remove the Old Key Fob:
- Take your currently working (old) key fob and insert it into the key slot.
- Remove the old fob immediately.
- Repeat this insert and remove action four more times in quick succession.
- On the fifth insertion, leave the old fob inserted into the slot.
3. Door Cycling:
- Open and close the driver’s side door six times. Do this at a moderate pace.
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 remains illuminated, indicating you’ve successfully entered programming mode.
5. Program the New Key Fob:
- Insert the new, unprogrammed key fob into the slot.
- Leave the new fob in the slot for a full minute. Keep an eye on the blinking red anti-theft light.
- Wait until the red anti-theft light stops flashing and turns off completely. This signifies that your new key fob has been successfully programmed for the start/stop function.
6. Completion of Basic Programming:
- Remove the new key fob from the slot.
- You have now completed the basic START/STOP programming.
Next Steps:
- If your new key fob has a chrome logo and your Prius is equipped with the Smart Key System (SKS), proceed to PROCEDURE B to program remote lock/unlock and Smart Key functionality.
- If your new key fob has a black logo and your Prius does not have SKS functionality, proceed to PROCEDURE C for programming remote lock/unlock features.
Procedure B: Programming Remote Lock/Unlock & Smart Key System (SKS) Functionality (For Chrome Logo Key Fobs)
This procedure is specifically for chrome logo key fobs and 2007 Prius models equipped with the Smart Key System (SKS). It will enable the remote lock/unlock functions and the convenience of the Smart Key System, allowing you to start and operate your Prius without physically inserting the fob.
1. Prepare the Vehicle:
- Open the driver’s side door and leave it open. Ensure the driver’s door is unlocked. Other doors can be either locked or unlocked; it doesn’t matter.
- Make sure there is no key fob in the key slot.
2. Insert and Remove Old Fob (Twice):
- Within 5 seconds, insert your old, working key fob into the slot and remove it immediately.
- Repeat this insert and remove action one more time.
3. Door Cycling (Twice):
- Within 40 seconds of completing step 2, close and then open the driver’s side door twice.
4. Insert and Remove Old Fob (Once):
- Within 40 seconds of completing step 3, insert the old key fob into the slot and remove it once.
5. Door Cycling (Twice Again):
- Within 40 seconds of completing step 4, close and open the driver’s side door twice again.
6. Insert Old Fob and Close Door:
- Insert the old key fob into the slot and close the driver’s door.
7. Cycle the Power Button (Without Braking):
- Without pressing the brake pedal, press the power button.
- Wait for one second, press the power button again.
- Wait for another second, and then press the power button a third time to turn the car back off. It’s crucial not to press the brake pedal during this step.
8. Remove Old Fob and Enter “Add Mode”:
- Remove the old key fob from the slot.
- You 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 might vary slightly depending on the specific 2007 Prius model, but it should cycle at least once.
- If the doors do not cycle, return to step 1 and repeat the procedure. If the doors cycle, proceed to step 9.
9. Program the New Key Fob(s):
- These steps (9a, 9b, 9c, 9d) should be started within 40 seconds of completing step 8.
9a: Program Old/Master Fob:
- Press and hold the Lock and Unlock buttons simultaneously on your OLD/MASTER key fob.
- Hold for a couple of seconds. The door locks should cycle once to indicate successful programming of the old fob.
- If you do not get this lock cycle, it might be due to a weak CR 2032 battery in your old fob. Replace the battery and try again from step 9a.
9b: Program New Fob:
- Press and hold both the Lock and Unlock buttons simultaneously on your NEW key fob.
- Hold for about 1.5 seconds.
- Some users have reported needing to repeat this step twice for successful programming. If it doesn’t work the first time, try executing this step twice.
9c: Finalize New Fob Programming:
- 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 of the new fob.
- It might take a moment for the lock/unlock cycle to occur. Wait patiently, even up to a minute. If there’s no cycle after a minute, proceed to step 10 and test the SKS functions to see if they work.
9d: Program Additional New Fobs (Optional):
- If you have more new key fobs to program, repeat steps 9a, 9b, and 9c for each additional new fob.
10. Exit Programming Mode:
- To end the programming session, simply open and then close the driver’s door, or insert any key fob into the key slot.
Procedure C: Programming Remote Lock/Unlock Functionality (For Black Logo Key Fobs – Non-SKS Models)
This procedure is for black logo key fobs designed for 2007 Prius models without the Smart Key System (SKS). It will program the remote lock and unlock functionalities for your new key fob.
1. Vehicle Preparation:
- Open the driver’s door, ensuring no key fob is in the slot and all doors are unlocked.
2. Insert and Remove Old Fob (Twice):
- Within 5 seconds, insert your old, working key fob into the slot and remove it immediately.

- Insert the old key fob into the slot and remove it once.
5. Door Cycling (Twice Again):
- Close and open the driver’s side door twice again.
6. Insert Old Fob and Close Door:
- Insert the old key fob into the slot and close the driver’s door.
7. Cycle the Power Button (Without Braking):
- Without pressing the brake pedal, press the power button.
- Wait for one second, press the power button again.
- Wait for another second, and then press the power button a third time to turn the car back off. Ensure you do not press the brake pedal during this step.
8. Remove Old Fob and Enter “Add Mode”:
- Remove the old key fob from the slot.
- You are now in “add mode.”
9. Verify “Add Mode”:
- The car should automatically lock and unlock the doors twice to confirm it has entered add mode.
10. Program New Fob (Button Press):
- **Press and hold both buttons (Lock and Unlock) on the new key fob simultaneously for about 1.5 seconds.**11. Finalize New Fob Programming:
- **Within 3 seconds of step 10, press just the Lock button on the new key fob.**12. Verify Successful Programming:
- **The car should respond with one quick lock/unlock cycle to confirm that the new fob is successfully programmed.**
- **If the car responds with two lock/unlock cycles, it indicates that the programming was unsuccessful.** In this case, try the procedure again, ensure your new fob is not defective, or consider if you have reached the maximum number of fobs that can be programmed to your Prius.13. Exit Programming Mode:
- **To end the programming session, open and then close the driver’s door, or insert any key fob into the slot.**Important Notes and Tips:
- Genuine Toyota Fobs are Crucial: Always use brand new, genuine Toyota key fobs purchased from an authorized dealer for guaranteed compatibility and full functionality.
- Battery Condition: A weak battery in your old key fob can cause programming issues, especially in Procedure B. Consider replacing the battery in your old fob if you encounter difficulties. CR 2032 batteries are commonly used in these fobs.
- Practice Run: It’s recommended to do a “dry run” of the steps without the fobs to familiarize yourself with the sequence, especially for the door and power button cycling steps.
- Patience is Key: Some steps, especially waiting for lock/unlock cycles, might require a little patience. Don’t rush the process.
- Part Numbers: For reference, here are the OEM part numbers for 2007 Prius key fobs:
- OEM Fob Part # for Smart Access (Chrome Logo, SKS): 89994-47061
