Early Punto designs used a basic mechanical key or a "Fiat Punto Replacement Key Code 1" system. These keys contained a fixed-code transponder chip. When the key was placed into the ignition, the car's immobilizer read a static code. If it matched the code kept in the ECU, the engine would start.
The Second Generation and Grande Punto (1999-- 2010)
With the introduction of the Punto MK2 and later the Grande Punto, Fiat transitioned to "Fiat Code 2." This system utilized a rolling code transponder. Unlike the fixed code, the rolling code modifications whenever the car is started, making it significantly harder for burglars to bypass the immobilizer through signal "smelling."
The Late Models (Punto Evo and 2012+ Models)
The last generations employed advanced remote flip keys with incorporated circuits. These keys handle not only the engine immobilizer however likewise offer remote main locking, boot release, and alarm activation. These keys need specific diagnostic software application to program into the vehicle's body control module (BCM).

The blade folds into the deal with (the "flip" system).Emergency Situation Service Keys: Occasionally provided with older models, these were often blue or brown and were intended for use when the primary secret was lost, though they typically did not have complete remote performance.Key Technical SpecificationsFunctionCode 1 System (Early)Code 2 System (Mid)BCM Linked (Late)CommunicationRepaired TransponderRolling Code TransponderRolling Code + RF RemoteCommon Chip TypeT5/ ID33ID48 (Megamos)ID46/ PCF7946FrequencyN/A433 MHz433.92 MHzConfiguring ToolStandard ClonerOBD DiagnosticsAdvanced Diagnostic/ EEPROM3. Typical Issues with Fiat Punto Keys

Remote Button Failure
The micro-switches inside the remote crucial fob are soldered to a circuit board. Repeated pressure can trigger these switches to break away or fail electrically. Owners often find they can start the car however can not open it remotely.
Transponder Corruption
While unusual, the transponder chip inside the secret can lose its synchronization with the automobile.

Step 2: Programming the Transponder
The new secret should be introduced to the car's computer. There are 2 primary methods this is attained:
OBD2 Programming: A professional plugs a diagnostic tool into the vehicle's OBD port and "teaches" the car to recognize the brand-new crucial ID.Pre-coding/EEPROM: On numerous Fiats, the secret should be "pre-coded" using data pulled from the automobile's BCM (Body Control Module) before it can be completed through the OBD port.Comparison of Replacement MethodsApproachSpeedExpenseReliabilityMain DealershipSlow (3-10 days)High (₤ 200 - ₤ 350)Very HighMobile LocksmithQuick (Same day)Medium (₤ 120 - ₤ 180)HighDO IT YOURSELF/ OnlineVariableLow (₤ 30 - ₤ 60)Low (Needs specialized tools)5. Essential Maintenance Tips for Owners

If the key is immersed in water, eliminate the battery right away and dry the internals with isopropyl alcohol.The "Code Card" Importance: When Puntos were offered brand-new, they included a plastic "Code Card" consisting of a 5-digit electronic code and a mechanical essential code. Keeping this card safe can substantially reduce the expense of setting new keys.Replace Batteries Proactively: The remote part of the key utilizes a CR2032 or CR2016 battery. If the series of the remote starts to reduce, replace the battery immediately to avoid the remote from losing its "sync."Use a Key Cover: Silicone covers can soak up the shock if the secret is dropped, safeguarding both the transponder chip and the plastic case.6.
