DME, CAS & Module Programming
New, used and replacement modules almost always have to be programmed to your vehicle’s VIN and immobilizer before they will work. An unprogrammed module won’t start the car, or it throws “module not recognized” and communication faults. We program and match ECUs, DMEs, CAS units and other control modules so they fit your vehicle like the original.

Don’t replace it — repair it.
Most failed modules can be repaired for a fraction of the dealer replacement price, and come back cloned to your vehicle so there’s no extra programming visit.
