Lonsdor FT02 PH0440B vs LT20 8A+4D Smart key

What is the major difference from the Lonsdor FT02 PH0440B 8A+4D and LT20 8A+4D prox boards? When I read both specifications, they seem the same.

FT08-PH0440 is a Lonsdor’s copy key that you can use their Toyota AKL software and copy a key from the existing keys in the system by sniffing through the push start button. You can also clone over it from an existing working key but remote RKE function will not work on both keys at same time.

LT-20 boards are their new boards that you can use as an emulator to turn ignition on also you can precode it with proper P4 value and frequency to make a programmable key to the car. So you program it as if you were programming a normal key.
