This is the "brain" of the key. It contains the remote-entry transmitter and, in numerous cases, the transponder chip that enables the engine to start.

3. The Transponder Chip

In some older or particular luxury models, the transponder chip is a small, different glass or carbon piece tucked into a corner of the shell. In newer models, it is incorporated straight onto the PCB.
