The First Generation (1993-- 1999)

Early Punto designs utilized a fundamental mechanical key or a "Fiat Code 1" system. These keys consisted of a fixed-code transponder chip. When the key was placed into the ignition, the car's immobilizer checked out a static code. If it matched the code stored in the ECU, the engine would begin.

The Second Generation and Grande Punto (1999-- 2010)

With the intro of the Punto MK2 and later the Grande Punto, Fiat transitioned to "Fiat Key Replacement Code 2." This system utilized a rolling code transponder. Unlike the repaired code, the rolling code changes whenever the car is begun, making it significantly harder for thieves to bypass the immobilizer by means of signal "smelling."

The Late Models (Punto Evo and 2012+ Models)

The last generations used sophisticated remote flip keys with incorporated circuits. These keys handle not only the engine immobilizer however likewise provide remote central locking, boot release, and alarm activation. These keys require customized diagnostic software to program into the lorry's body control module (BCM).

2. Kinds Of Fiat Punto Keys

There are three primary physical formats for Fiat Punto keys discovered on the market today:

• Non-Remote Transponder Keys: These are basic plastic-headed keys without buttons. They consist of a transponder chip that enables the car to start however require the user to by hand turn the lock to unlock.
• Three-Button Remote Flip Keys: The most typical modern-day version, featuring buttons for locking, opening, and trunk release. The blade folds into the handle (the "flip" system).
• Emergency Service Keys: Occasionally offered with older designs, these were frequently blue or brown and were meant for use when the primary key was lost, though they frequently did not have full remote performance.

Key Technical Specifications

3. Typical Issues with Fiat Punto Keys

Despite their robust design, Fiat Punto keys are vulnerable to use and tear. Because they are handled daily, a number of mechanical and electronic failures can take place.

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 typically discover they can begin the car but can not open it from another location.

Transponder Corruption

While rare, the transponder chip inside the key can lose its synchronization with the car. This is frequently brought on by dropping the key from a height or exposing it to strong electro-magnetic fields.

Step 1: Cutting the Blade

Modern Fiat Puntos utilize a "Sip22" blade profile, which is a flat, laser-cut track. This needs a computerized key-cutting maker that traces the original secret or utilizes the car's essential code to cut a fresh blade from a blank.

Action 2: Programming the Transponder

The brand-new key needs to be presented to the car's computer. There are 2 primary methods this is attained:

1. OBD2 Programming: A professional plugs a diagnostic tool into the car's OBD port and "teaches" the car to recognize the brand-new essential ID.
2. Pre-coding/EEPROM: On numerous Fiats, the secret needs to be "pre-coded" utilizing data pulled from the vehicle's BCM (Body Control Module) before it can be finished by means of the OBD port.

5. Crucial Maintenance Tips for Owners

To prevent the high expenses of emergency situation call-outs, Fiat Punto owners need to follow these best practices concerning their automobile keys:

• Protect the Circuit Board: Avoid getting the essential damp. If the secret is submerged in water, get rid of the battery instantly and dry the internals with isopropyl alcohol.
• The "Code Card" Importance: When Puntos were sold new, they included a plastic "Code Card" containing a 5-digit electronic code and a mechanical crucial code. Keeping this card safe can considerably minimize the expense of configuring new keys.
• Change Batteries Proactively: The remote part of the key utilizes a CR2032 or CR2016 battery. If the range of the remote begins to decrease, replace the battery immediately to avoid the remote from losing its "sync."
• Use a Key Cover: Silicone covers can absorb the shock if the key is dropped, securing both the transponder chip and the plastic case.

6. Often Asked Questions (FAQ)

Q: What should I do if my only key is lost?A: If all keys are lost, a mobile vehicle locksmith professional is typically the very best choice. They can translate the lock to cut a new blade and use specialized software application to draw out the security pin from the car's ECU to configure new transponders.

Q: Why is the "Code" light (padlock icon) flashing on my dashboard?A: This suggests that the immobilizer system does not acknowledge the secret in the ignition. It could be due to a defective transponder, a harmed antenna ring around the ignition barrel, or a blown fuse in the BCM.

Q: How long does it require to set a new key?A: For a skilled locksmith professional with the right devices, the entire procedure-- consisting of cutting the blade and programming the electronics-- generally takes between 30 and 60 minutes.
