I purchased this for a 2004 town and country . Ran 100.00 . It fired up the car and as soon as the security system took over it quit.  I found out you cannot program replacement electronics for these years of cars . I had to put the original switch back in and call a locksmith to make a key for the original system . That was 300.00 . If your wanting to replace your unit with this one the security system electronics will not work . The mechanical parts will work  along with the electrical part of the ignition switch at the bottom.  I could have returned the part back to the seller but I didnt. Wasnt his fault . Selling as is for mechanical parts at a loss .
