I have been struggling with the issue of non stand key malfunction for 3 years, I had bought my vehicle to many mechanics to fix the problem. Unfortunately the problem could not be fixed. Then one day while I was online I discovered ECU pro, I sent my CAS to them and amazingly they fixed the issue and returned my CAS to me im 4 days. I am so happy that I found them,they are a a 'n amazing company with great customer service. I was informed when they recieved my part and also when it was repaired,they also sent me a video showing my CAS working in another vehicle.
