Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I was a bit nervous about ordering a replacement ECM for my 2009 Cadillac SRX, but this one arrived quickly and was exactly as described. The VIN was already programmed, so installation was smooth and hassle-free—just plugged it in and everything fired right up. It saved me a ton of time compared to having to get it programmed separately. The fit and function were perfect, and my SRX runs like new again. Overall, a great experience from start to finish.
After my old ECM failed, I wasn’t sure if I’d find a direct replacement that would work without extra programming, but this unit was spot on. It came fully VIN programmed, which meant I didn’t have to make an extra trip to the dealership. The shipping was fast, and the instructions were clear enough for me to handle the install myself. Now my Cadillac starts up smoothly every time, and all the systems are running perfectly. Definitely highly recommend this if you need a ready-to-go ECM.
