On the 5th time, leave it in the ignition, then: 2. Open and close the driver's door 6 times. 3. Remove the master key. The security light should now stay lit red. 4. Insert the newly cut key. The security light should be blinking red; wait about 60 seconds until the light stops blinking and turns off. 5. Remove the new key. Insert the old master key and start the engine and turn it off.

It is very similar to programming your keys. Using your instructions as a template: 1. Using a master key (original key), insert (and remove) it from the ignition 6 times. On the 6th time, leave it in the ignition, then: 2. Open and close the driver's door 7 times. 3. The security light should now stay lit red. When you remove the master key, this will be the only key that is still programmed. After this, you should be able to add your keys. I only have 3 keys myself, but I believe that ~2004 Toyotas will allow 5 master keys, and 3 valet keys to be programmed. Since erasing and reprogramming is so easy, I might just erase and reprogram if I even have to give my master key to anyone. This would keep people from making duplicates and driving off with my car.
