2016 BMW 3 Series All Keys Lost using ACDP2

Summary

The presenter demonstrates an all-keys-lost key-programming job for a 2016 BMW 3 Series using an ACDP2. The vehicle owner’s son had lost the key, so the presenter worked with the car’s DME and FEM modules off the vehicle.

Workflow

1. Read the DME’s ISN (immobilizer security data) and save it along with the vehicle’s VIN.
2. Open the FEM and back up its data before programming.
3. Identify the appropriate replacement key by its radio frequency. The presenter determines that the 434 MHz key is correct.
4. Follow the ACDP2 app’s step-by-step programming process, then restore the original FEM data.
5. Program the replacement key using the previously read ISN and VIN. The presenter reports that programming completes successfully.

The presenter says the programmed key should start the car, but the video does not show an in-vehicle test. He also notes that the process depends on good connections and correctly identifying the key and memory components.
