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.

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.

The ECM arrived quickly and was exactly as described, already programmed to my Jeep’s VIN which saved me so much hassle. Installation was straightforward and truly plug-and-play, no complicated setup required. After swapping it out, my Grand Cherokee runs flawlessly, and I’m very impressed with the quality and service provided. Definitely a reliable solution if you need an ECM replacement without any guesswork.

I was pretty nervous about replacing the ECM on my 2009 Jeep Grand Cherokee, but this unit arrived ready to go and was exactly as described. The VIN programming was spot on, so once I plugged it in, the Jeep fired right up without any hiccups. It saved me a ton of time compared to trying to get a used module reprogrammed by a dealer. Shipping was surprisingly quick too, which was a relief since I needed my vehicle back on the road ASAP. Overall, this was a smooth, hassle-free experience and I’d definitely recommend it to anyone facing a similar repair.
