The First Generation (1993-- 1999)
Early Punto models used a fundamental mechanical secret or a "Fiat Code 1" system. These keys contained a fixed-code transponder chip. When the secret was placed into the ignition, the car's immobilizer read a static code. If it matched the code saved in the ECU, the engine would start.
The Second Generation and Grande Punto (1999-- 2010)

Keeping this card safe can considerably decrease the cost of programming new keys.Change Batteries Proactively: The remote part of the essential utilizes a CR2032 or CR2016 battery. If the variety of the remote begins to reduce, replace the battery right away to avoid the remote from losing its "sync."Use a Key Cover: Silicone covers can take in the shock if the key is dropped, safeguarding both the transponder chip and the plastic case.6.
