Decoding the Fiat Code System

Fiat uses a security website protocol called the Fiat Code System. Inside every contemporary secret is a transponder chip. When the secret is inserted into the ignition or the proximity sensor is set off, the car's Body Control Unit (BCU) sends an electro-magnetic pulse to the secret. The essential reacts with a special alphanumeric code. If the code matches the one saved in the car's memory, the engine immobilizer is deactivated.

The "Blue Key" Mystery: On older Fiat models produced in the late 90s and early 2000s, owners were frequently offered with a "Blue Key" and a "Red Master Key." The Red Key was vital for configuring brand-new keys into the system. In the present Fiat 500 (2007 onwards), this system has been replaced by a digital code card that includes a 5-digit electronic security code.

Typical Issues with Fiat 500 Keys

Even the most well-designed keys are susceptible to wear and tear. Fiat 500 owners often report a number of recurring problems.

The remote functions of a Fiat 500 key are powered by a CR2032 lithium battery. When the battery begins to die, the remote range will reduce, or the car might fail to react to button presses totally.

2. Broken "Flip" Mechanism

The spring-loaded mechanism in the flip secret is a frequent point of failure. Over time, the internal plastic housing can crack, or the spring can lose tension, triggering the blade to hang loose or stop working to emerge when the button is pressed.

3. Button Wear

The rubberized buttons on Fiat 500 keys are prone to degradation. Frequent use can result in the rubber tearing or falling out, exposing the micro-switches beneath to wetness and particles, which ultimately causes circuit board failure.

4. Transponder Desynchronization

To set a brand-new key, the software needs to access the car's Body Computer and "handshake" with the brand-new transponder chip. Without the 5-digit electronic code (found on the original code card), the procedure is a lot more complicated, often requiring the locksmith professional to "check out" the EEPROM chip directly from the car's computer.
