2. Fixed-Code Transponder Keys (Fiat CODE1)
Introduced in the mid-90s, these keys contain a small RFID (Radio Frequency Identification) chip. The car’s immobilizer reads a set code from the chip. If the code matches, the engine starts. These often featured a popular “Red Master Key,” which was needed to set brand-new brother or sister keys.
3. Rolling-Code Transponder Keys (Fiat CODE2 and beyond)
Most Fiats produced after 2000 use a rolling-code system. Every time the key is utilized, the code modifications based on a complicated algorithm. This makes the keys much harder to clone and requires specialized diagnostic equipment to set the lorry’s ECU (Engine Control Unit) to acknowledge a new key.
4. Remote Flip Keys and Smart Keys
Modern Fiats, such as the 500X or the 500e, make use of remote “flip” keys or proximity clever keys. Keyless entry systems enable drivers to begin the car with the push of a button, offered the key is inside the cabin. These are the most intricate keys to replace due to the integrated circuit boards that manage central locking and alarm systems.
