Key information — 2003 BMW 7 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 reference7 Series — CAS1 candidate; source range 2001-2008; U.S. year intersection 2001–2008

Immobilizer: CAS1

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.

Listed model years: 2001–2008. Source: Transpondery — BMW CAS/FEM/BDC application summary

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 2003 BMW 7 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.
