2. Non-Remote Key: Often offered as a spare, this key consists of a transponder chip for the immobilizer but does not have buttons for remote main locking.
3. Keyless Entry/Go Fobs: Found on newer designs and the electric 500e, these permit the motorist to unlock and start the car while the secret remains in their pocket or bag.

Decoding the Fiat Code System

Fiat makes use of a security Fiat 500 Electric Key procedure called the Fiat Code System. Inside every contemporary secret is a transponder chip. When the key is placed into the ignition or the proximity sensor is activated, the car's Body Control Unit (BCU) sends an electro-magnetic pulse to the secret. The key reacts with an unique alphanumeric code. If the code matches the one kept in the car's memory, the engine immobilizer is shut down.

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

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

2. Broken "Flip" Mechanism

The spring-loaded system in the flip key is a frequent point of failure. Gradually, the internal plastic real estate can crack, or the spring can lose tension, causing the blade to hang loose or stop working to emerge when the button is pushed.

3. Button Wear

The rubberized buttons on Fiat 500 keys are vulnerable to degradation. Frequent use can cause the rubber tearing or falling out, exposing the micro-switches below to moisture and debris, which ultimately results in circuit board failure.

4. Transponder Desynchronization

Periodically, if the car battery or the key battery dies totally, the key might lose its synchronization with the immobilizer. This leads to the "Car with Lock" symbol appearing on the dashboard, preventing the engine from beginning.

• Pros: Usually less expensive than the dealership and typically uses mobile service (they come to the car).

To set a new secret, the software application needs to access the car's Body Computer and "handshake" with the brand-new transponder chip. Without the 5-digit electronic code (discovered on the initial code card), the procedure is much more complicated, frequently needing the locksmith professional to "check out" the EEPROM chip straight from the car's computer.
