Part	Function	Common Failure Mode
CR2032 Battery	Powers the remote locking and hands-free transponder signals.	Loss of variety, overall remote failure.
Internal Microswitch	Signs up physical clicks of the lock/unlock buttons.	Solder joints crack; buttons stop clicking or reacting.
RFID Transponder Chip	Communicates with the car's immobilizer to permit engine start.	Chip cracks or disconnects from the board (frequently triggers "Card Not Detected" errors).
Induction Coil	Charges the battery (in some versions) and functions as an emergency backup receiver.	Wire breaks due to card flexing.
