He was most likely telling the truth. This type of immobilizer system has been there since the very late nineties. And yes, I know of immobilized cars that have been towed to the dealerships to get unlocked. And yes, three strikes rule exist on most immobilizers. And further, if I am not mistaken, there is only a fixed small number of times that you can manually reprogram keys before the system permanently stops accepting any new keys.Update...Was cautioned by technician that if I had inserted that unprogrammed key "one more time" system would have shut the car down to "prevent attempted theft". I think that is more BS, but what do I know.
