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 recently replaced the ECM on my 2019 Toyota Highlander Hybrid with this VIN-programmed unit, and I couldn’t be happier. It arrived quickly, well-packaged, and everything about the plug-and-play setup was seamless. The moment I installed it, the vehicle fired up without any issues, and I didn’t have to deal with any annoying warning lights or error codes. It saved me a ton of time and headache compared to trying to reprogram a generic module. The support team was also very responsive when I had a quick question. Overall, this was exactly what I needed to get my Highlander running perfectly again.

I recently replaced the ECM on my 2019 Highlander Hybrid with this unit, and I have to say, it was exactly what I needed. The fact that it came pre-programmed for my VIN made installation a breeze—I just plugged it in and the car fired up without a hitch. Shipping was surprisingly quick, which was a relief because I needed my vehicle back on the road fast. I was a bit nervous about doing this myself, but the customer support team was very helpful when I called with questions. Overall, it saved me a lot of time and hassle compared to going through the dealership. Highly recommend this for anyone looking for a smooth, plug-and-play solution.
