Key information — 2021 BMW 4 Series
These are candidate key, remote, vehicle-equipment, or immobilizer-system references for this model year. Match the VIN, original key, chassis, build date, trim, ignition type, equipment, and market as applicable before ordering. Separate entries are alternatives or overlapping source applications; do not combine them into one key or treat a candidate as confirmed equipment for the individual vehicle.
Immobilizer system reference4 Series G22 — BDC03 candidate; U.S. model years 2021–2024; source interval 2020-2024
Immobilizer
BDC3 (BDC03 in source)
Candidate application, not a VIN-level identification. Model year alone may not identify the system: confirm the chassis, build date, market and installed equipment. Transition-year overlaps are expected. This reference does not establish chip, blade, FCC ID, radio frequency, proximity features or service availability. Retailer tool-support reference. The source's full row is 4 Series | G22/G23/G26/G82/G83 | 2020-2024. Only G22 is mapped here, after intersecting the source interval with a separately confirmed U.S. chassis/model-year window. The primary BMW references establish vehicle identity, not the immobilizer. Source build months remain necessary to resolve boundary years; no coverage is inferred after 2024.

The primary BMW references establish vehicle identity, not the immobilizer. Source build months remain necessary to resolve boundary years; no coverage is inferred after 2024.
A part number identifies a part; an FCC ID identifies a radio device approval. A matching frequency alone does not establish compatibility. Catalog references do not confirm local stock or service availability.
About Your 2021 BMW 4 Series
The model name or year alone does not establish the installed immobilizer, key type, or programming method. Confirm the VIN, market, trim, and any replaced components against the source references and the vehicle.
Confirm your vehicle details and whether any working keys remain so we can quote the applicable service before dispatch.
Before your key appointment
Have your VIN, trim, and any existing keys available. Describe how you start the vehicle: turn a key, press a button, or use both. Tell us whether any working keys remain and whether you need a spare, a replacement remote, or help after losing every key. Include a photo of the original key and its label when available.
