If your vehicle has an IMMO or PATS system, it will require a key relearn after installation. You can visit your local locksmith for help.
We also offer a full cloning service. We transfer all security data to the replacement unit, so it will be a plug&play installation.
For all European cars, Hyundai, and Kia vehicles, we recommend adding our cloning service as a bundle.
For American and Japanese cars, we recommend doing a key relearn on-site.

I was really impressed by how quickly this ECM arrived, and the fact that it was completely plug-and-play made the whole process so much easier than I expected. The unit fit perfectly on my 2012 Mazda 3 2.0L, and having it VIN programmed already saved me a ton compared to dealer prices. Communication with the seller was clear and prompt, which made the whole experience stress-free. Installation went smoothly, and my car runs like new again.
