Losing or needing to replace your 2007 Toyota Prius smart key fob can be a stressful situation. The good news is, programming a new or existing key fob for your 2007 Prius can often be done yourself, saving you a trip to the dealership and potentially hefty fees. This comprehensive guide provides step-by-step procedures to program your 2007 Prius Smart Key Fob, whether you need to program it for basic engine start/stop functionality or for remote locking/unlocking and Smart Key System (SKS) features.
This guide is designed to be your go-to resource for understanding and executing the 2007 Prius smart key fob programming process. We’ll break down the different procedures based on your key fob type and the features you need.
Understanding Your 2007 Prius Key Fob
Before diving into the programming procedures, it’s important to understand the different types of key fobs that might be associated with your 2007 Toyota Prius. There are generally two types differentiated by the Toyota logo on the fob:
- Chrome Logo Key Fob: These fobs are typically associated with vehicles equipped with the Smart Key System (SKS). SKS allows for keyless entry and engine start by simply having the fob in proximity to the vehicle.
- Black Logo Key Fob: These fobs are generally for Prius models without the Smart Key System.
It’s also crucial to determine what functionality you need to program. There are two main levels of programming:
- Start/Stop Engine Functionality: This is the basic function that allows the key fob to start and stop your Prius when inserted into the key slot on the dashboard. This programming is generally required for all new fobs, regardless of whether they are chrome or black logo.
- Remote Lock/Unlock & Smart Key System (SKS) Functionality: This advanced programming is for chrome logo fobs on vehicles with SKS. It enables remote locking/unlocking of doors and the smart key features.
Now, let’s move on to the programming procedures.
Procedure A: Programming for Start/Stop Engine (All Fobs)
This procedure is for programming the basic start/stop engine function. It should be performed for all new 2007 Prius smart key fobs, regardless of the logo type or SKS functionality.
Steps:
- Vehicle Preparation: Get inside your 2007 Prius, close and unlock all doors. Ensure the car is completely turned off.
- Insert and Remove Old Fob (Rapidly): Take your old, working key fob and insert it into the key slot on the dashboard. Remove it immediately. Repeat this insert and remove action four times in a row. On the fifth insertion, leave the old fob inserted into the slot.
- Door Cycling: Open and close the driver’s side door six times.
- Remove Old Fob: Take out the old key fob from the slot. At this point, your Prius should be in key fob programming mode. You’ll likely notice the red anti-theft light on the dashboard remain illuminated (not flashing).

- Insert New Fob (and Wait): Insert the new 2007 Prius smart key fob into the slot and leave it there for a full minute. Observe the red anti-theft light on the dashboard. It will be blinking initially, and when the programming is successful for the start/stop function, the light will stop flashing and turn off.
- Remove New Fob: After a minute and when the anti-theft light goes dark, remove the new key fob from the slot. The basic START/STOP engine programming is now complete.
Next Steps:
- If you have a chrome logo key fob and your Prius has Smart Key System (SKS) functionality, proceed to Procedure B to program the remote lock/unlock and SKS features.
- If you have a black logo key fob or your Prius does not have SKS, proceed to Procedure C for remote lock/unlock programming.
Procedure B: Programming Chrome Logo Fobs with SKS (Remote & Smart Key)
This procedure is specifically for programming chrome logo key fobs on 2007 Prius vehicles that are equipped with the Smart Key System (SKS). This will enable remote lock/unlock functionality and the convenience of the smart key system.
Steps:
- Driver Door Open (Key Slot Empty): Open the driver’s side door and leave it open. Ensure no key fob is inserted in the key slot and that the driver’s door is unlocked. The other doors can be either locked or unlocked.
- Insert and Remove Old Fob Twice (Quickly): Within 5 seconds, take your old, working key fob, insert it into the slot, and remove it. Repeat this insert and remove action one more time (for a total of two times).
- Door Cycle (Twice): Within 40 seconds of completing step 2, close and then open the driver’s side door twice.
- Insert and Remove Old Fob Once: Within 40 seconds of completing step 3, insert your old key fob into the slot and remove it once.
- Door Cycle Again (Twice): Within 40 seconds of completing step 4, close and open the driver’s side door twice again.
- Insert Old Fob and Close Door: Insert the old key fob into the slot and close the driver’s door.
- Power Button Sequence (No Brake): Without pressing the brake pedal, press the power button on your Prius. Wait for one second, press it again, wait another second, and then press it a third time to turn the car back off.
- Remove Old Fob: Take the old key fob out of the slot. You should now be in “add mode” for key fob programming. Within 3 seconds, the car should automatically lock and unlock the doors to confirm it has entered add mode. The exact 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.

- Program Old and New Fobs: These steps (9a, 9b, 9c) should be started within 40 seconds of completing step 8.
- 9a. Old/Master Fob (Lock & Unlock Hold): Press and hold both the Lock and Unlock buttons simultaneously on your OLD/MASTER key fob for a couple of seconds. The door locks should cycle once to indicate successful registration of the old fob. If you don’t get this cycle, it might be due to a weak CR 2032 battery in your old fob. Try replacing the battery and repeat from step 9a.
- 9b. New Fob (Lock & Unlock Hold): Immediately after step 9a, press and hold both the Lock and Unlock buttons simultaneously on your NEW 2007 Prius smart key fob 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. New Fob (Lock Button Press): Within three seconds of step 9b, press just the Lock button on the NEW key fob. If successful, the door locks should cycle once more to confirm the new fob is programmed. Be patient, the lock/unlock cycle might take a few moments. If you wait longer than a minute and there’s no cycle, proceed to step 10 and test the SKS functions to see if programming was successful despite the lack of immediate lock cycle confirmation.
- 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 you want to program. If you are finished programming fobs, proceed to step 10.
- End Programming: To finalize the programming process, either open and then close the driver’s door or insert any key fob into the key slot.
Procedure C: Programming Black Logo Fobs (No SKS – Remote Only)
This procedure is for programming black logo key fobs for 2007 Prius vehicles that do not have the Smart Key System (SKS). This procedure will enable remote lock/unlock functionality.
Steps:
- Driver Door Open (Key Slot Empty, Doors Unlocked): Open the driver’s door, ensure no fob is in the slot, and all doors are unlocked.
- Insert and Remove Old Fob Twice (Within 5 Seconds): Insert your old, working fob into the slot and remove it twice within 5 seconds.
- Door Cycle (Twice): Close and open the driver’s door twice.
- Insert and Remove Old Fob Once: Insert and remove the old fob once.
- Door Cycle Again (Twice): Close and open the driver’s door twice again.
- Insert Old Fob and Close Door: Insert the old fob into the slot and close the driver’s door.
- Power Button Sequence (No Brake): Without pressing the brake, press the power button three times (with a one-second pause between each press) to turn the car to the “off” position from accessory mode.
- Remove Old Fob: Remove the old fob from the slot. You are now in “add mode.”
- Confirmation of Add Mode: The car should automatically lock and unlock the doors twice to confirm it is in add mode.
- New Fob Button Hold: Press and hold both buttons (Lock and Unlock) on the new 2007 Prius key fob simultaneously for about 1.5 seconds.
- New Fob Lock Button Press: Within 3 seconds, press only the Lock button on the new fob.
- Confirmation of New Fob Programming: The car should respond with one quick lock/unlock cycle to indicate successful programming of the new fob. If the car responds with two lock/unlock cycles, it indicates the programming was unsuccessful. In this case, try the procedure again, ensure your fob is not faulty, or that you haven’t exceeded the maximum number of fobs that can be programmed to your Prius.
- End Programming: To exit programming mode, open and then close the driver’s door or insert any fob into the key slot.
