JLR Keyless Vehicle Module (KVM) & Programming Service | PN: FK72-19H440-CA

---

Technical Description & Service Options

The Keyless Vehicle Module (KVM) is the central security ECU in modern Jaguar Land Rover vehicles. It is responsible for key fob validation, immobiliser authentication, and controlling the keyless entry & go functions. A failed or corrupted KVM will result in a no-start condition, often accompanied by a “Smart Key Not Found” message on the instrument cluster.

This product page is for the genuine JLR KVM unit with part number FK72-19H440-CA, a common 2-plug module found in various Jaguar and Land Rover models. Due to JLR's advanced security architecture, a KVM cannot be simply swapped from another vehicle. It is electronically locked to the original vehicle's powertrain and body control modules. We provide a professional solution to overcome this challenge.

Our Core Services for this KVM Module:

• New Genuine Virgin KVM Unit: We supply a brand new, genuine JLR KVM module in a “virgin” state. This module is ready to be programmed into a vehicle using JLR's Pathfinder or SDD diagnostic tools by a qualified technician. This is the ideal option for workshops with dealership-level programming capabilities.
• KVM Cloning & Data Transfer Service (Mail-In): If your original KVM is still readable (even if it's malfunctioning), you can mail it to us. We will perform a full data extraction from the module's MCU (reading both D-Flash and P-Flash memory) and transfer it to a new unit. The new KVM will be returned to you as a plug-and-play solution, requiring no further programming. This retains all original keys and vehicle configuration data.
• KVM Virgin Dump Service (for All Keys Lost): In a situation where all vehicle keys are lost, we require you to send us your vehicle's Body Control Module (BCM). We can extract the necessary security data from the BCM and use it to prepare a new KVM. This service will include a new set of keys pre-programmed to the module, restoring full functionality to your vehicle.

The JLR KVM Security Protocol

The JLR security system creates a cryptographic link between the KVM, the Body Control Module (BCM), and the Powertrain Control Module (PCM/ECM). When a new KVM is installed, it must be commissioned to the vehicle via a process called “Immobiliser Setup”. During this process, the KVM learns the security identifiers of the other modules and is permanently locked to the vehicle's VIN. Our programming service bypasses the need for online dealership tools by directly manipulating the microcontroller's memory, creating a seamless and cost-effective solution.

Common Failure Symptoms of FK72-19H440-CA:

• “Smart Key Not Found” or “Smart Key Not Recognized” message.
• Vehicle does not crank (no-start condition).
• Inconsistent key fob detection.
• Complete failure of keyless entry and start functions.
• Fault codes related to internal KVM errors or communication loss.
• Water ingress is a very common cause of failure for these modules.
