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.
Sending several modules? Add them all — one box, one return-shipping charge.

Best for
- Fuse box flooded by water intrusion — the classic JLR no-start after rain
- Used / second-hand CEM fitted and it will not work
- Corroded CEM that still powers up — clone it out before it dies completely
- Avoiding a dealer-only new-module order plus a tow and coding session
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
Before you order
You diagnose, we service the module.
We don't have your car and we don't diagnose it. Order once you or your mechanic have confirmed this module is the cause. If the work is completed and the car still has the same symptom because of another fault, the work is still done — a bench re-test under warranty is free.
A clone copies what is in your module.
We transfer the data as we read it. If another shop or tool already worked on the module — an unfinished clone, a tune, a delete — that data can come across too. Tell us before you ship.
What "plug-and-play" means.
No dealer programming should be needed when your original data is intact, the donor matches your module (same type, hardware and software family) and the rest of the car works. It isn't a promise that the car will start or run.
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 $29.95, 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
