2009 ford Taurus key programing.
Wife has lost both keys. Locksmith tried to reprogram new key but failed. He left a key that he cut that turns on ignition. This key is metal only with no chip. Ignition has been tried with this key and of course nothing. Little lock shaped anti-theft light is flashing. #2 locksmith came out, said his programmer (Computer ) initialized but then stopped and gave an error message. He then tried to plug in a diagnostics computer in order to erase error codes. This caused the instrument cluster to go black or dead. When he unplugged the tool, instrument lights came back on. Is this because the Anti-Scan has not been reset from being activated earlier by trying to start car with the metal key that had no chip?
