Just got a 2001 accord ex, it has a security system, looks like original factory, with stickers on window, and handheld remote (python). Anyway, got 2 new keys made, and altho keys, unlock doors, and can crank engine, can not start, but with 1 "factory" key the engine starts, is there a chip in the key, that the copies dont have and therefore the car is being immobilized. thanks for your help
