BMW X4 key references by model year
These source-listed applications cover different years, products, and equipment alternatives. They are candidates for identification, not a single specification for every X4. Confirm the VIN, market, trim, build date, installed equipment, and key label before ordering.
Years use the US catalog selection window. Source ranges can include other markets; only their overlap with selectable years is grouped below. Missing years or references require individual identification and do not establish whether a vehicle has an immobilizer.
2015–2018 · 1 source-listed application
Immobilizer system reference
X4 — CAS4 candidate; source range 2014-2018; U.S. year intersection 2015–2018
Immobilizer
CAS4
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. Third-party series/year summary; the source does not specify a market or distinguish model year from production year. The lookup range is capped at 2018; the source range is retained separately.
X4 — BDC2 candidate; source range 2018+; U.S. year intersection 2018–2018
Immobilizer
BDC2
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. Third-party series/year summary; the source does not specify a market or distinguish model year from production year. The lookup range is capped at 2018; the source range is retained separately.
X4 G02 — BDC02 candidate; U.S. model years 2019–2021; source interval 2018.04–2021.07
Immobilizer
BDC2 (BDC02 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 X4 | G02 | 2018.04–2021.07. Only G02 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.
X4 F98 — BDC02 candidate; U.S. model years 2020–2021; source interval 2019.04–2021.07
Immobilizer
BDC2 (BDC02 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 X4 | F98 | 2019.04–2021.07. Only F98 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. This record is specifically for the X4 M variant, not every vehicle under the broader X4 selector.
X4 G02 — BDC03 candidate; U.S. model years 2020–2024; 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 X4 | G02 | 2020-2024. Only G02 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.
Separate entries are alternatives or overlapping source applications; do not combine them into one key. A part number, FCC ID, or frequency alone does not confirm compatibility, local stock, or service availability.
About Your BMW X4
Select the exact model year to see its service details and referenced applications. 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.

Frequently asked questions
What details do you need to quote a BMW X4 key?+
Have the VIN, model year, trim, ZIP code, and any existing key available. Tell us how you start the vehicle and whether any key still starts it. A photo of the key and its label helps identify the replacement.
Which key services do you offer for the X4?+
Spare-key and all-keys-lost service: 2015–2021. Spare-key service only; all-keys-lost is not currently offered: 2022–2025. These are model-year service groups; confirm your exact vehicle before booking.
Is programming included for a BMW X4?+
Confirm service availability first. The individual quote will specify the parts, cutting, programming, location, and lead time that apply to your vehicle.
Do I have to tow my X4 to a dealer?+
Do not arrange transport based on the model name alone. Confirm the exact vehicle, required service, and whether an on-site appointment is available first.
Will any replacement BMW key work?+
No. Match the exact model year, market, installed equipment, and part or remote details. A similar-looking key or matching radio frequency does not establish compatibility. We confirm the hardware when quoting.
