Hi. Just bought a 2008 Dodge Avenger. Got a great deal on it. Past owner wasn’t sure what was wrong with it other than it gave his girlfriend problems. Noticed that the key was in bad shape and the chip was missing. I have title, but this is my first Dodge. I need to go pick it up from where I bought it, but it won’t start. I think it has something to do with the anti-theft system. There is no fab and only the one tore up key. What can I do? Trying to avoid the cost of a locksmith. Any advice or instruction would be greatly appreciated. Thanks.
