BMW 3 Series 5 7 Cas4+ System Smart Remote Key 4 Button HU92 Blade 433mhz 7953 is designed specifically for use with BMW 3 Series vehicles that use the CAS4+ system. This smart remote key serves as a critical component for vehicle access and security, allowing remote locking, unlocking, and ignition without traditional key insertion. The included HU92 blade corresponds to the physical key portion, suitable for the vehicle’s mechanical lock requirements.
The unit features four buttons, typically used for locking, unlocking, trunk release, and panic alarm functions, providing convenient keyless control over vehicle access and security features. Operating at 433 MHz, this remote is compatible with the specific communication frequency for BMW smart keys using the CAS4+ immobilizer system.
When replacing your key, compare the old unit’s blade type and button layout to ensure compatibility. Attention to the CAS4+ system designation is essential, as it distinguishes this key from earlier or different BMW remote generations. If unsure about fitment or programming, consulting the sales desk or submitting a request for a part can help secure the correct solution.
