FAQs

Yes, this key is made to work with every Toyota Prius Prime model from the 2023 to 2026 model years. It does not matter what trim level your car is. This key will be a perfect match for your vehicle as a direct replacement part.

2. Does this Smart Key support on-board programming?

No, you can not program this key by yourself. It takes professional programming using special tools. You will be required to deliver it to an authorized auto locksmith or a Toyota dealer. They possess the necessary equipment to code the key to the security system of your car.

3. What tools are recommended for programming this key?

Professional tools, such as an Autel or the Toyota Techstream system are necessary in programming. They are not ordinary consumer instruments. This is the reason why we suggest a certified automotive locksmith to do the programming process or your local Toyota dealer to do it on your behalf.
