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

Alternatives for Obtaining a Replacement Key
When a Fiat Punto owner needs a new secret, they generally have 3 courses to select from. Each has its own set of pros and cons relating to cost, speed, and convenience.
1. The Main Dealership
Purchasing a key through a Fiat main dealer guarantees that the owner gets an authentic OEM (Original Equipment Manufacturer) part.
Process: The owner must provide the V5C logbook (proof of ownership) and ID. The dealership orders the key from Italy based upon the chassis number (VIN).Pros: Guaranteed quality; initial Fiat branding.Cons: Often the most expensive option; usually takes 5 to 10 working days for the key to arrive; the car should frequently be towed to the dealership for last shows.2. Professional Auto Locksmiths
Mobile vehicle locksmith professionals are often the most effective choice for Fiat owners. Many specialists carry the needed software application to bypass the dealer-only restrictions.
Process: The locksmith professional travels to the car's location. They use specialized decoding tools to check out the lock wafers and cut a new blade on-site. They then plug a diagnostic tool into the OBD-II port to program the new transponder chip.Pros: Mobile service (no towing needed); typically 30-50% more affordable than a dealer; same-day service.Cons: Quality of aftermarket essential shells can vary.3. The "DIY" Hardware Route
While some owners attempt to purchase "blank" keys from online marketplaces, this is hardly ever successful for the typical individual. The hardware might be inexpensive, but the specialized software required to "handshake" the new key with the fiat Punto Replacement key ECU costs countless dollars.
The Missing "Key Code Card"
Historically, every brand-new Fiat was provided with a plastic "Code Card." This card consisted of a five-digit electronic code and a mechanical code.
Electronic Code: Required for configuring brand-new keys via the OBD-II port.Mechanical Code: Tells the locksmith professional exactly how to cut the blade without having to take the lock apart.
If a second-hand Punto owner does not have this card, a locksmith professional or dealership can usually recover the codes from the Fiat database or by "reading" the car's ECU, though this typically incurs an additional charge.
Estimated Costs for Replacement
The rate of a replacement key differs significantly based upon the model year and whether the owner needs a remote-entry function.

If a yellow "Key" or "Padlock" sign is revealing, the car does not acknowledge the transponder code.
