Next time you play with a 4C Toyota try programming in a master into a valet position and vice versa via onboard programming. Both keys will swap fine into either position.
Like i said 4C are a very basic transponder thats why they are no longer used.
Yes you are correct about the 4c chip , today i program a camry with a valet key from another car as a master and it work perfect . so 100% correct about the chip .

To close the programing in the toyota corolla , with the last key switch on and off 5 times and then touch the brake 1 time .then pull the key out .

i did all this today .
