the keys have a small "Pill" that is the transponder for the immobilizer
The circuit board is for remote unlock, frunk and trunk release

You can swap components from key to key to make 1 good one form the 2 semi good ones

Searching before you ask a question is a good idea

1 prevents duplicate threads
2 you may learn stuff
3 prevents duplicate threads
4 your question will be answered
5 prevents duplicate threads
