you have a problem with the theft system (immobilizer)
get the master key (which is probably the key you are using) and try the following:
turn ignition on and off 3 times within 5 seconds then remove key and put key back in and try to start it
if that doesn't work put key turn ignition on and wait for ten minutes then turn it back off and then on for another ten minutes then off and on for another ten minutes then start vehicle.
Dear: Billy the Car still will not start, Iam going try a couple of more times is there any way to disconnect or bypass the immobilizer
to by pass the immobilizer will probably cost more than fixing it.
