Program the computer on a 2001 Dodge Durango
That's not good. Only way to program a new key to the car is to visit a dealer or a locksmith. Make sure you get two this time in case you loose one, because you can program a second one by yourself if you have the first.
But the car was working with the spare key for awhile up until the security sensor light turned on now the car won't even start the dealers is too expensive is there another way around it
