In a Ford F-150, Theft code 13 indicates an incorrect key is being used to start the truck. The key contains a transponder that communicates with the truck's receiver to disable the alarm system. If there is a mismatch, a code will be generated. Code 13 commonly occurs when dealing with multiple trucks and grabbing the wrong key by mistake. To check, use the fob's button to lock or unlock the truck to ensure you have the right key for the vehicle.
It's the only key available, I simply replaced my battery.
I attempted to reset the key fob for my 2009 Ford F-150, but now my truck won't start. What should I do next? Error code 13.
While cranking the engine, try using starting fluid to see if it starts running. If it starts running while using the starting fluid, it is unlikely that the issue lies with the key, but rather with a fuel problem.
If your Ford F150 is showing a theft code 13, it indicates that you are trying to use the wrong key to start the vehicle.
I had an error code 13 due to theft, but it disappeared when I discovered that the airbag switch was unplugged. After cleaning and reconnecting it, the airbag light turned off and the truck started working properly again.
I'm dealing with a similar issue. Someone stole my truck and tried to start it with a screwdriver. Now, after retrieving it from impound, the engine cranks but doesn't start.
I've been dealing with a persistent issue for weeks now - sometimes it works, sometimes it doesn't. I've tried various solutions, like disconnecting the battery from the PCM, but nothing seems to help. Then, I discovered a green plug underneath my steering wheel where the key goes in - I believe that's the transponder. By unplugging and re-plugging that while turning the key forward, I was able to disable it successfully four times. This tip might be useful for others facing a similar problem, as it has at least helped me get home without needing a tow.
