'No key detected' But they key is in the ignition

Asked by May 30, 2018 at 08:12 AM about the 2012 Ford Focus

Question type: Maintenance & Repair

2012 Ford Focus. Key is in the ignition and they car will tell me no key
detected. It will also trigger my anti theft system when I unlock the door with the
key. And my alarm will go off when I go to start the car if it doesn't read my key
right away. I don't have a FOB. Just a manual key. I did just buy it used.

That sounds like the transponder in the key went bad, a dealer can cut a new and reprogram the security system to recognize the new key or if you have a very good locksmith, they can do the same thing only cheaper. This is going to be expensive either way but cheaper with the locksmiths.
