- The PCB (Printed Circuit Board): The electronic "brain" that sends signals to the car for locking, unlocking, and beginning.
- The Battery: The source of power for the remote functions.
- The Transponder Chip: A small, typically glass or carbon-encased chip that interacts with the car's immobilizer. Without this chip, the car will not start, even if the key turns the ignition.

3. Drawing out the Electronics
When the case is open, the circuit board and battery are eliminated. This is an ideal time to inspect the battery voltage and change it if necessary.
