Toyota Prius 2003 - Remote Programming (Unlock and Lock) - Help please.

I have a Toyota Prius 2003 (Included the vehicle details in the picture) and I have the original key that came with the car (Shown in the picture).

I have purchased a key and programmed it to the car by using the below instructions: (It starts the the engine).

Step 1.

This will program the fob to Start/stop engine while it is inserted into the key port.

1. Get into the car, close and unlock all doors and ensure the car is off
2. Insert old fob (your fob that currently works) into slot and remove it 4 times in a row, and insert it a fifth time but leave it in there!

1. Open and close driver door 6 times.
2. Remove old fob from slot. Car is in fob programming mode at this point. Red anti-theft light remains on.
3. Insert new fob and leave in the slot for a full minute.

Watch the blinking red anti-theft light on the dashboard.

When it stops flashing and goes dark, your new fob is all set.

5. Remove the new fob and you're done with the START/ STOP portion of programming

The issue that I’m having is I can’t get the remote part to work which unlock and locks the door.

Here are the instructions that I’m using:

I get to Step 5, and the power door locks should lock and then unlock automatically, indicating successful entry into programming mode which it does (It cycle once - So when I pull the key out, it locks and then unlock) but then from step 6 is where it does nothing when pressing the unlock and lock button on the remote on the old remote (which is already programmed to the car as it’s the original) and the new one also does nothing.

I have checked and both fob are the same frequency - It was like 433.92.

if anything could please help with this part.

kind regards
