Hey guys,
So I've attempted my first bench program in which I actually attempted to "lock" the ECM using my own key..... during the flash process it said "invalid key was entered ECM will remain unlocked"

So, when I went to try again it won't flash now, it keeps saying it can't unlock it I guess..... what do I do know?! At least the tunes made it in okay but am I dead in the water to make any changes to it?

I'm sending this one to a customer.
