Hi Guys.

I have a client that lost keys on this old Renault Megane. I tried to read BCM chip but failed so decided to go the immo off way.
I tried an immo off file found here on the forum and cut pin 58 and car starts but doesn't run properly and doesn't rev up nicely.
Tried another file and doesn't start at all. So seems we need to use the original file and do immo off in the original file.
Does anybody have a proven 100% working method for immo off.
Here is the Original file 29F200.
