Body Module Cloning

Copying everything from a faulty body control module onto an identical donor unit, including the immobiliser data and the settings for your car. The donor then works as if it were the original, with your existing keys and no dealer coding.

All the same thing under different names. BCM is body control module, BSI is what Peugeot and Citroen call it, body computer is the Fiat name, CEM is the Volvo and Land Rover name, SAM is the Smart name. It is the unit that runs the lights, locks, wipers, windows and the immobiliser, and it is usually built into the fusebox.

The original unit and a donor carrying the same part number, which is printed on the label. Find your number on this page to check we can do it, and that is the number to search for when you buy a donor. Send a photo of both labels first if you want us to confirm the donor matches before you buy it.

Often. Many failures are in the power stages while the memory holding your car’s data is intact. If the original cannot be read at all, cloning is not possible and we tell you before any work is done, and before you are charged for it.

For a few makes the same car was built with two body modules that look identical from the outside, and only one of them can be cloned. A photo of the label, and sometimes of the board, tells us which one you have before you post anything.

Usually not. We only need the two units, so you can post them in or drop them off. Bring the car if you would rather we removed and refitted the unit ourselves.
