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.

Shipping was lightning fast and the plug-and-play unit installed without a hitch, saving me a bundle compared to dealer prices. Great communication and a smooth process from start to finish.
Sean Richardson –
Received my 2005 Cadillac CTS ECM quickly with free shipping, and it arrived perfectly VIN programmed—couldn’t be happier with the smooth plug-and-play setup.
James Johnson –
I ordered the 2005 Cadillac CTS PCM and was impressed by how smoothly everything went. The VIN programmed unit arrived quickly, and the shipping cost was very reasonable, which was a nice bonus. Installation was straightforward thanks to their plug-and-play setup, and the car has been running perfectly since. Customer service was also responsive and helped answer a couple of technical questions I had before purchase.
