Mercedes-Benz ECU Cloning
A replacement Mercedes engine computer has to match your car's immobilizer before the engine will start. We clone your original ECU to the replacement 1:1, so it plugs in without a dealer visit.

FAQ
What do I send you?
Your original module and the replacement (donor) module, with a note showing your eBay order number. Our shipping address comes with your order.
Do the part numbers have to match?
Yes. Part number, hardware and software numbers must match, and both units must be from the same manufacturer. Send us photos of both labels before you buy if you're not sure.
Will my keys still work?
Yes. Immobilizer data is copied, so your existing keys keep working with the replacement module.
Not sure what you need?
Send us the vehicle and part number. We reply by email.
