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 purchased the 89661-02C43 ECM for my 2004 Toyota Corolla, and I’m very satisfied with the whole experience. The unit arrived quickly with free shipping, which was a nice bonus. It came fully VIN programmed and ready to install, making the swap hassle-free. Their customer service was also very responsive, answering my questions promptly throughout the process.
