2020 bmw. BDC2 all key lost

Summary

The video describes an all-keys-lost job on a 2020 BMW with a BDC2 system. The presenter says the vehicle must be physically present for this procedure, unlike the BDC1 process, because the key is prepared directly for the car.

At a high level, the workflow involves reading data from a vehicle module, modifying and rewriting the relevant IMDATA, then programming and learning the replacement key. The subtitles are unclear about some individual steps and equipment, so they do not provide a reliable step-by-step guide.

The presenter warns that this method may void the vehicle’s warranty. It can also prevent a future dealer-supplied key from working; restoring the original IMDATA would be necessary before such a key could work.

The job is described as straightforward and roughly 15 minutes longer than the comparable BDC1 procedure, with no interruptions during this job.
