Theft mode
I have a 1999 Ford F-150 with an after market stereo, one of my friends was messing with it and accidentally knocked the stereo off while the key was on, putting the truck into theft mode, I was wonder what ways there are to fix this. I have tons of oarts trucks to get parts from. I searched online to see what I could do but couldn't find a thing. I was wondering if there is a computer or something that I can change to fix the problem or if there is a way to fix it. Any and all help is appreciated!

I am not sure I understand the problem. He turned the aftermarket stereo off by the switch on the stereo, and the factory theft system on the truck activated? Did it alarm or did you just cycle the keyswitch?

on the after market stereo there is a digital screen with all the buttons that controls the stereo, and on the bottom of the stereo there's an eject button that ejects the screen part and leaves the CD player and stuff, but the part that comes off plugs into the CD player, the key was in the on position and then the piece fell off and then all the lights went off and it said theft mode blinking on the dash.

The head unit was installed before I purchased the truck, I don't have a code, if I change the head unit to a stock one will it fix it?

Can you repeat this problem anytime you want? Is that how you took the picture above? Or it did it that one time and now it won't go off?

Here are both diagrams I can find for the factory stereo in your truck, and I do not see any factory theft connections.

Your photo is of the THEFT light in the cluster which has absolutely nothing to do with the stereo. I recommend that, before proceeding, you read the section in your owner's manual that describes how the THEFT light is supposed to behave during normal operation and how it will operate if there is an issue. Once you understand that and how those operations are commonly described, drop back on and describe SPECIFICALLY what you are observing using the terminology that is common to your owner's manual.
