Hi Scotty, Pls Help. My Car ECU is Already Faulty And im planning to buy One. ive searched on the internet and find a Refurbished ECU same Part number as my ECU, But it says It is A LOCKED ECU, what does that mean? can it still be reprogram to my car?

it would have to be unlocked or don't buy it. Otherwise you could not reprogram it to work on your car

Okay Thank you So much! :D
