Immobilizer Faults ("Code" Light)
A common sight on Fiat control panels is the "Padlock" or "Code" light. If this light stays illuminated when the key is turned, it indicates that the car does not recognize the transponder chip. This could be due to a faulty chip in the key or a failure in the antenna ring around the ignition barrel.
Battery Depletion
The remote performance of a Fiat Punto essential depends on a small CR2032 or similar lithium battery. While this does not impact the car's ability to begin (as the transponder is usually passive), it will stop the remote keyless entry from working.
3. The Importance of the Fiat Code Card
When a Fiat Punto is acquired brand-new, it originally features a "Code Card." This card consists of a mechanical code (for cutting the blade) and an electronic code (a five-digit pin for programming).

Technical Insights: How Programming Works
Modern Fiat Spare Key Punto keys are configured through the OBDII (On-Board Diagnostics) port. The process generally involves:
Cutting the Blade: Using a CNC laser cutter to match the physical lock wafers.Pre-coding: The transponder chip need to be "prepared" with vehicle-specific information before it can be found out by the car.Programs: Connecting a tablet-based developer to the car to inform the BCM to accept the brand-new crucial ID.
In some older designs (Punto Mk2), if all keys are lost, the BCM needs to be eliminated and the "EEPROM" (Electrically Erasable Programmable Read-Only Memory) chip need to be read straight on a bench to create a brand-new secret.
