Read the vehicle list as a starting point
The listed model range helps narrow the choice, but a successful replacement still depends on the car’s BSI system, frequency and programming process.

A simple three-part check
Shape, signal and system must agree
The most useful way to compare a replacement key is to move from the visible shell to the hidden electronics, then to the vehicle’s actual BSI mode.
Confirm the 433MHz frequency and PCF7946 chip requirement against the original key or the vehicle service information.
Select Delphi or Marelli BSI based on the vehicle system, then confirm the local programming method before fitting.
