For those new to the Toyota Prius, understanding the key fob system can initially be a bit confusing. Let’s clarify the differences, especially concerning the “Smart Key System”.
The “Smart Key System” (often referred to as “Smart Entry / Smart Start” in older models like the 2004 Prius) represents Toyota’s advanced key technology. This system allows for a seamless, keyless experience. With the Smart Key, you can keep the key fob in your pocket or bag. Simply approach your Prius, grab the door handle, and the car will automatically unlock. Once inside, pressing the brake pedal and then the ‘Power’ button will start the vehicle.

If your Prius is not equipped with the Smart Key System, a more traditional approach is needed. You’ll need to press the unlock button on your remote to open the doors. Then, to start the car, you must insert the key into the designated slot on the dashboard before pressing the Power button.
Visually, you can differentiate between the two types of remotes by the Toyota logo color. Smart Key System remotes feature a silver Toyota logo, while non-SKS remotes have a black Toyota logo.
It’s worth noting that while non-SKS remotes can technically function with a Prius equipped with the Smart Key System, and vice versa, you will only have access to the basic features. For instance, using a non-SKS remote with a Smart Key System car means you’ll still need to use the buttons on the remote and insert the key into the slot, even though the car has the Smart Key capability. Conversely, pairing a Smart Key remote with a non-SKS car won’t magically enable the Smart Key features.
In automotive terminology, “fob” often refers to a separate device on a keychain, distinct from the key itself. “Remote” typically describes the electronic key. In older vehicles, remotes for door locks were often separate from the physical key, making “fob” an appropriate term. However, in modern cars like the Prius, the remote and key are integrated into one unit. Therefore, “remote” or simply “key” are more accurate terms when discussing your Prius key fob, which is essentially the electronic key itself. The physical key component is primarily for emergency access, such as when the car battery is depleted and you need to manually unlock the door.
