🚗 Coverage
For the X300 Pro4, OBDSTAR states the same immobiliser functions as the Key Master DP Plus, except for some luxury cars: Lamborghini, Maserati, Ferrari, Bentley, Alfa Romeo, Abarth. OBDSTAR no longer publishes a product page or a coverage list specific to the X300 Pro4. The closest up-to-date official list is that of the Key Master 5, sold at the same level in the range. We check your vehicle, line by line, before you order.

| Our advice | If you already know the X300 interface | The default choice at this level of the range | For recent vehicles and the options |
Good to know: some functions need an extra accessory, for example a gateway cable or an all keys lost cable: see our cables and adapters. The X300 Pro4 is a key tool: it does not calibrate clusters and does not reset airbag ECUs. For the luxury cars listed above, ask us before ordering.
