Button Failure

The remote central locking buttons are soldered onto a printed circuit board (PCB) inside the key. Regular usage or unintentional drops can desolder these switches or damage the rubber membrane, preventing the owner from locking or unlocking the car from another location.

Immobilizer Faults ("Code" Light)

A typical sight on Fiat dashboards is the "Padlock" or "Code" light. If this light stays lit up when the key is turned, it suggests that the car does not acknowledge the transponder chip. This might be due to a faulty chip in the essential or a failure in the antenna ring around the ignition barrel.

Battery Depletion

The remote performance of a Fiat Punto crucial relies on a small CR2032 or similar lithium battery. While this does not impact the car's ability to start (as the transponder is typically passive), it will stop the remote keyless entry from working.

Modern Fiat Keys Replacement Punto keys are set via the OBDII (On-Board Diagnostics) port. The process usually includes:

1. Cutting the Blade: Using a CNC laser cutter to match the physical lock wafers.
2. Pre-coding: The transponder chip should be "prepared" with vehicle-specific information before it can be discovered by the car.
3. Shows: Connecting a tablet-based developer to the car to inform the BCM to accept the brand-new essential ID.

In some older models (Punto Mk2), if all keys are lost, the BCM must be removed and the "EEPROM" (Electrically Erasable Programmable Read-Only Memory) chip need to read straight on a bench to generate a new key.
