Land Rover / Range Rover / Jaguar CEM (Fuse-Box BCM) Cloning — Mail-In Bench Service

Water got into the fuse box and now your Range Rover won't start, or a used CEM you fitted refuses to work? Mail in your original central electronic module plus a matched donor and we clone the VIN, config, and immobilizer data across on the bench — so the replacement drops in plug-and-play. Cloning where supported, verified by part number first.

Will This Fix My Problem?

Honest answer: here's exactly what this service fixes — and what it doesn't.

Fixes:

  • ✓Water intrusion flooded the fuse box / CEM and the vehicle now will not start
  • ✓Multiple simultaneous electrical faults traced to a failed central electronic module
  • ✓Used CEM installed and it refuses to work — carries the donor car's identity, not yours
  • ✓Dead CEM being replaced and you want your VIN, config, and immobilizer data carried over
  • ✓Corrosion- or heat-damaged CEM that still powers up — clone it before total failure
  • ✓You want a second-hand fuse-box module made plug-and-play for your exact VIN

Won't fix:

  • ✗Does not include the donor CEM — you source a part-number-matched used unit (we verify the numbers first)
  • ✗Does not clone an original that is internally dead or unreadable — nothing can be copied off a module that will not respond
  • ✗Does not program or virginize the key / RFA / KVM module — see our JLR KVM virginize service
  • ✗Does not repair a no-start caused by fuel, battery, grounds, wiring, or a separate failed control module
  • ✗Does not guarantee a bench-only clone on the newest platforms — some may need online JLR tools; we verify yours first
  • ✗Does not remove or bypass the factory immobilizer — the immobilizer relationship is preserved
  • ✗Does not bypass proof of ownership
  • ✗Does not cover the engine ECM — see our Jaguar / Land Rover CPLA ECM clone service
  • ✗Does not cover key programming or all-keys-lost — see our Range Rover / Jaguar key programming service

Flooded fuse box on a JLR? The CEM carries the whole car's identity

On Land Rover, Range Rover, and Jaguar the CEM sits low in the vehicle and a leaking sunroof drain or windscreen seal can pour water straight into it — the classic no-start-after-rain with a fistful of unrelated faults. The module stores the VIN, factory configuration, and immobilizer relationship, so a bare used unit from a breaker will never work: it still thinks it belongs to the donor car. This service clones your original's complete data onto a matched donor so it drops in plug-and-play. A dead or unreadable original cannot be cloned, some newest platforms may need online tools, and proof of ownership is required for any immobilizer-related work — a technician verifies your VIN and both module labels before you ship anything.

Shipping Instructions

These details are also emailed to you the moment your payment clears.

Verify first: text or email us your VIN plus clear photos of your original CEM/BCM label and the donor's label — a technician confirms the part numbers are a compatible match, and whether your platform can be done on the bench, before you ship. Then send both units (original + donor) to PO Box 120241, Arlington TX 76012 if you ship USPS — or 1009 Oakwood Ln # 120241, Arlington TX 76012 if you ship UPS or FedEx (UPS and FedEx cannot deliver to a PO Box). We clone the data on the bench, test communication, and ship both back via the return option you pick at checkout (Standard $24.95, UPS 2-Day $54.95, or UPS overnight $94.95).

What to include in your box

  • Your original CEM / fuse-box BCM (must power up and respond to be cloned) AND the donor module
  • Jaguar two-module cars: both the front and rear CJB units if your platform uses them (we confirm which)
  • Year, make, model, and platform code if known (e.g. 2010 Range Rover Sport L320)
  • VIN of the vehicle
  • The JLR part number off BOTH module labels — we pre-verify the match
  • What is wrong now: water intrusion, dead module, cranks-no-start after a used-CEM swap, etc.
  • Proof of ownership (title, registration, or bill of sale)
  • Your name, return address, and an email or number we can reach you at

Frequently Asked

Still have a question? Text us — replies in minutes.

What is the CEM and why does a used one never just work?
The CEM (Central Electronic Module) is the central junction box / fuse-box body control module on Land Rover, Range Rover, and Jaguar. It stores the VIN, the car's factory configuration, and the immobilizer relationship. A used module from another vehicle still carries that donor car's identity, so it will not work in yours until your original data is cloned onto it. That is exactly what this service does.
Which vehicles does this cover?
Range Rover L322 (2002-2012) and L405 (2013-2021), Range Rover Sport L320 (2005-2013) and L494 (2014-2021), LR3 / Discovery 3 (2004-2009), LR4 / Discovery 4 (2009-2016), L462 Discovery 5, L560 Range Rover Velar, and the LR2 / Freelander 2 central junction box. On the Jaguar side: the XF 2009-2015 front and rear CJB data transfer, and the XE, XF, F-Pace, and I-Pace body control modules carrying JPLA-14F041-BG or JPLA-14F041-BD part numbers. The newest chassis are verified case-by-case — some may need online JLR tools rather than a bench clone. Send your VIN and a photo of the module label and we confirm your exact car before you ship.
My fuse box got flooded — is that what killed it?
Very often, yes. The CEM sits low in the vehicle and a blocked sunroof drain or a failed seal can flood it, which is the classic JLR no-start after heavy rain, usually with a cluster of unrelated electrical faults. If your original still powers up and responds we can clone it onto a healthy donor; if the water killed it outright and it will not respond, there is nothing left to read — see the next answer.
What if my original CEM is completely dead?
Cloning requires reading the data off your original, so a module that will not power up or respond cannot be cloned. In that case a matched donor still needs the correct VIN, configuration, and immobilizer data written to it, which on most JLR platforms means dealer-level or online programming rather than a bench clone. Contact us with your VIN and symptoms first and we will tell you honestly whether a bench clone is possible before you ship anything.
Do you supply the donor module?
No — you source a used donor (eBay, salvage yard, breaker) and we verify compatibility before you buy or ship anything. Match the JLR part number on your original's label as closely as possible; send us photos of both labels plus your VIN and a technician confirms the pair will work, free.
Does the immobilizer stay active after the clone?
Yes. Cloning preserves the factory immobilizer relationship exactly — your existing keys keep working and the car's security stays intact. This is not an immobilizer delete or a security bypass, and proof of ownership (title, registration, or bill of sale) is required before any work begins.
Is this the same as your JLR key / KVM service?
No. The KVM / RFA virginize service deals with the keyless-vehicle / remote-function module for key programming and all-keys-lost work. This service clones the CEM / fuse-box body control module — the central junction box that stores VIN, configuration, and the immobilizer relationship. They are different modules and different jobs; if you are not sure which you need, send your VIN and symptoms and we will point you to the right one.
How much is it and how does the mail-in work?
It is $250 flat. After a technician verifies your VIN and both module part labels, you ship the units to Auto Module Lab in Arlington, TX. We clone the data on the bench, test communication, and ship both back with tracking — return speed your choice at checkout (Standard $24.95, UPS 2-Day $54.95, or UPS overnight $94.95). Inbound shipping to the lab is customer-paid with your choice of carrier.
