• An RFID Transponder Chip: Communicates with the car's immobilizer system to permit the engine to start.
• A Remote Central Locking Circuitry: Sends radio frequency (RF) signals to lock and unlock the doors.
• An Emergency Mechanical Blade: A physical metal key hidden inside the card to open the driver's door if the battery passes away.
• A Power Source: A little lithium coin battery (normally CR2025 or CR2032) that powers the remote functions.

Over years of use, exposure to severe temperature levels, wetness, and being rested on in back pockets, the fragile internal solder joints and copper coils inside the card can crack or break.

• Component Refurbishment: Technicians re-solder damaged connections, replace faulty microswitches, or repair damaged transponder coils.
• Shell Replacement: Because the original casing should be cut open, technicians typically house the repaired circuit board inside a new, beautiful plastic shell.
• Testing: Before handing the card back to the client, the service technician tests the remote frequency and the immobilizer chip on a devoted testing rig.

Expense Comparison: Repair vs. Dealership Replacement
