wanted to make this follow-up post regarding this subject. on a previous post a member asked if the maptuner x can reprogram brp keys. and a bunch of guys all said no you cant reprogram keys with it. I looked long and hard and couldn't find a video on youtube showing this process even though I knew you could because I did it myself. so I created a video of the processcheck it out. now some might ask why would you need to or want to reprogram a key. good question for me I didn't need a slow key I wanted a second performance key incase mine was damaged or lost dealers in Michigan are charging over $80.00 to do this. so its just another great feature that the maptuner x offers over the others.
