The standard car key for the Fiat 500, Grande Punto, Punto, and Punto Evo includes a casing, blade, electronic circuit board, and chip. It has three buttons and operates at 433 MHz, with a PCF7926ATT chip, ID46, and a Delphi system. The blade and chip can be transferred from the old casing, while the key can be programmed and copied at a key-cutting center.
