9.Using wrong key type some people make copies of their keys and forget that certain vehicles have micro chips inside the key you can’t see causing the anti theft system to kick in causing the starting system to shut down. Fords are known for this the black plastic on the top of the key has a chip inside you cannot see and the copy blank looks identical to the original except there’s no chip inside check to see if your anti theft light is on in the dashboard..
