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 a bit nervous ordering an ECM online, but this 2017 GMC Sierra ECM arrived exactly as described and was already VIN programmed, which saved me a ton of headaches. The plug-and-play setup was truly hassle-free, and my truck fired up right away without any issues.

Their communication was spot-on too; they responded quickly when I had a couple of questions about installation. Overall, this was a top-notch experience and I’d definitely buy from them again.
