as stinkola said its worthless dude ,,,i almost bought one locked for my 99 magnum 10 3/4 ton truck,,so i called around ,b&g and sct ,,,it will cost more to unlock it then put new tunes on it than one that is in working order,,
to get the one i was going to get would have cost me over 200 to unlock then 200 for tunes ,and shipping both ways & the price to buy it
,,,not to mention the waiting time to do it ,,,not tring to kill your sale but i ended up buying a new unused one with three working tunes for 275 ,,with free shipping
now mind you this was about 6 months back and they are selling new one way cheaper now
