I own a 2004, 9.3 Aero, auto transmission. The key suddenly will not register with the car and consequently, I cannot start the car. One other odd situation. The steering wheel is not locked. The car is parked in the garage, locked in park. Any suggestions?
The car's diagnostic system told me it does not recognize the key.
I tried both keys. Neither will work.
I also checked all fuses associated with starting the vehicle.
Key system to start the vehicle. The key itself will not turn to unlock the transmission and start the vehicle. I read a signal on the digital display that says the car does not recognize the key, but there is no ability to turn the ignition switch with the key. I believe the car will allow an unrecognized key to at least turn the ignition switch.
Last question, if I replace the ignition switch itself, in your opinion, will the car allow the keys to work or do I have two problems. Mechanical ignition switch, and electronic reset to recognize the key?
I am replacing the ignition switch as it is faulty. My next potential issue is the car recognizing the key once the new switch is in and operational. The car shop does not have diagnostic capability to scan codes.
Let me know if you have any comments about the car starting with the new switch. Don't want to spend another $18.00. Don't worry about a reply if it will cost me.
