Genuine Jaguar Land Rover factory central remote function actuator (RFA/KVM) immobilizer and smart key security control module. If your vehicle is ignoring your key fob commands, intermittently displaying a "Smart Key Not Found" error message on the instrument cluster, or refusing to turn on the ignition when pushing the start button, an internally failing KVM module is a classic issue. Swapping it out with this original hardware controller will allow you to restore the wireless vehicle security link.

Fitment note: Sourced from an original factory configuration. Please cross-reference your original module's stamped label part number sequence (FK72-19H440-AD / Lear Model code: 5E0770517 / Software version: RFA 30.3) to guarantee a direct hardware configuration match for your vehicle's security platform.

⚠️ Important Security Installer Note: Because the RFA/KVM module serves as a primary vehicle anti-theft gatekeeper, it stores the vehicle's unique VIN profile and synchronized transponder key codes. It will require professional programming via specialized diagnostic tools (such as JLR SDD or PATHFINDER) or an advanced bench EEPROM data clone to pair with your vehicle and link your original smart keys before operations can resume.

Warranty: 1 month warranty covering wireless security decryption loops and proximity key verification signal paths.
