Remote Key Shell for BMW CAS4, Fits 3/5/7 Series (2009-2016), X5, Z3, Z4 - Shell Only Replacement

Main Description

Keep your BMW key looking and functioning like new with this BMW CAS4 Remote Key Shell, designed for 3, 5, and 7 Series models from 2009 to 2016, as well as X5, Z3, and Z4 variants. This is a shell-only replacement—no interior electronics, transponder, or remote components are included. The key benefit is simple: you can extend the life of your existing key by swapping in a fresh, precisely fitted housing while transferring your internal components from the old remote. The result is a secure, reliable key that matches the original feel and fit.

The shell is crafted from durable ABS plastic with a metal element for added strength. It features a high-hardness surface with excellent chemical, heat, and corrosion resistance, and it’s designed to be a clean, gap-free fit with a smooth, logo-free exterior. The blade is uncut and copper-based, processed by vacuum heat to enhance resilience and ease of future cutting to your car’s profile. Please note that this is not a complete key by itself—the internal electronics and transponder are not included, and no logos are printed on the shell.

Compatibility covers a broad range of BMW keys, including CAS4/F system keys from 2009–2016 and 3/5/7 Series, X5, X3, Z3, Z4 variants, as well as related models listed in the fit references. To complete the setup, you simply move the internal components from your old remote into this new case and have the blade cut to your vehicle’s profile.
