JLR KVM Module (FK72-19H440-CA) – Virginized for Programming

The Keyless Vehicle Module (KVM), also known as the Remote Function Actuator (RFA), is the central security brain for the keyless entry and start system in modern Jaguar and Land Rover vehicles. It is responsible for validating smart keys, authorizing engine start via the immobiliser protocol, and controlling all passive entry and remote functions. A faulty KVM will render a vehicle immobile and inoperable.

At LR-Retrofit.com, we provide this critical component in a professionally “virginized” state, clearing all previous vehicle data and security pairing. This presents the module to the vehicle's network as a brand-new factory part, ready to be configured to a new VIN.

Common Scenarios Requiring KVM Replacement

Replacement of the KVM module is necessary under several critical conditions:

• “All Keys Lost” Security Lockout: If all registered keys are lost, JLR security protocols prevent the simple addition of new keys. A virgin KVM is required to rebuild the vehicle's key set.
• Internal Electronic Failure: The module can fail due to voltage spikes or component degradation, often logging specific DTCs related to internal faults or antenna circuits that cannot be cleared.
• Water Ingress/Corrosion: Due to its typical location, the KVM is susceptible to water damage, leading to short circuits and total failure of the PCB.
• Corrupted Software/Data: An interruption during a key programming sequence or module update can corrupt the KVM's memory, making it unresponsive.

Why a “Virginized” Module is Essential

A standard used KVM from a donor vehicle is cryptographically locked to the original vehicle's VIN and immobiliser data. It cannot be reprogrammed to another vehicle. Our virginizing process securely erases this data block, returning the module's microprocessor to a factory state. This is the only proper way to integrate a replacement module without compromising the vehicle's security architecture.

Verified Vehicle Compatibility

This `FK72-19H440-CA` module is fitted to a range of JLR platforms from approximately 2014-2017. However, you must verify the part number on your vehicle's original KVM before ordering, as several hardware variations exist.

Commonly found on models including:

• Range Rover (L405): 2014 – 2017
• Range Rover Sport (L494): 2014 – 2017
• Jaguar F-Type (X152)
• Jaguar XF (X250, X260)
• Jaguar XJ (X351)

Programming and Installation Procedure

Installation and programming must be performed by a qualified technician with access to genuine JLR diagnostic equipment.

1. Physical Installation: Disconnect the vehicle battery. Carefully remove the old KVM and install the virginized replacement. Reconnect all harnesses.
2. Module Programming: Connect the vehicle to JLR SDD or Pathfinder. Execute the “Configure new module – KVM” routine. The diagnostic tool will download the correct vehicle-specific software and configuration file from JLR servers and flash it to the new module.
3. Key Programming: Once the KVM is configured, execute the “Program new keys” procedure. All existing and new keys for the vehicle must be present during this process.
