When the key is turned, the car's On-Board Diagnostics (OBD) system sends a signal to the chip. If the code matches, the engine begins.

The Technical Process: How a Fiat Key is Replaced

Replacing a contemporary Fiat secret is a multi-step technical procedure that includes more than simply "cutting a key."

  2. Cutting the Blade: Using a CNC (Computer Numerical Control) laser cutter, a blank blade is cut to the specific specifications of the car's locks.
  3. Accessing the OBDII Port: The professional connects a programming device to the car's OBDII port (normally found under the dashboard).
  4. Extracting the Pre-Code: Fiat security systems need a "Security Pin" or "Pre-code" to permit new keys to be added. This is frequently discovered on a Code Card provided with the original automobile purchase. If the card is missing out on, professional locksmiths can extract this information straight from the car's Body Control Module (BCM).

  • Protect the Case: Silicon covers can protect flip keys from the impact of drops, which often shatters the delicate transponder chip inside.
  • Examine Insurance Policies: Some thorough insurance coverage or breakdown coverages consist of essential replacement as an optional add-on.
