Important Note
If your vehicle does not have an IMMO or PATS system, this unit will be directly plug&play.
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 with how quickly the ECM arrived after I placed my order. The unit fit perfectly and was truly plug-and-play, which made installation a breeze. Compared to the dealer’s quote, this service saved me a significant amount of money without compromising quality. The team’s communication throughout the process was professional and kept me informed every step of the way.
