2. Fixed-Code Transponder Keys (Fiat CODE1)
Introduced in the mid-90s, these keys consist of a small RFID (Radio Frequency Identification) chip. The car’s immobilizer checks out a set code from the chip. If the code matches, the engine starts. These typically featured a famous “Red Master Key,” which was needed to program brand-new brother or sister keys.
3. Rolling-Code Transponder Keys (Fiat CODE2 and beyond)
Most Fiats produced after 2000 usage a rolling-code system. Whenever the key is utilized, the code modifications based upon an intricate algorithm. This makes the keys much more difficult to clone and requires specialized diagnostic devices to program the vehicle’s ECU (Engine Control Unit) to recognize a brand-new secret.
4. Remote Flip Keys and Smart Keys
Modern Fiats, such as the 500X or the 500e, use remote “turn” keys or proximity clever keys. Keyless entry systems permit drivers to begin the car with the push of a button, supplied the secret is inside the cabin.
