Every Fiat Punto made after 1995 functions an immobilizer system. This is a security feature developed to avoid the engine from starting unless the right transponder chip is detected near the ignition barrel.

The dealer orders the key from Italy based upon the chassis number (VIN).Pros: Guaranteed quality; original Fiat Key branding.Cons: Often the most costly choice; typically takes 5 to 10 working days for the secret to show up; the car should typically be pulled to the car dealership for last programming.2. Professional Auto Locksmiths

The "DIY" Hardware Route
While some owners try to buy "blank" keys from online markets, this is seldom effective for the typical individual. The hardware might be cheap, but the specialized software needed to "handshake" the brand-new key with the Fiat ECU costs thousands of dollars.
The Missing "Key Code Card"
