Theft system light turns on a few seconds after I turn off my car

#1

2005 Chevy Classic. Sorry for posting twice but evidently I’m just full of car issues today.

First issue, my radio/clock wouldn’t shut off. So I pulled the fuse.

Now when I shut car off, my theft system light lights up after about 10 seconds. When i turn my key to ON, it shuts off after another 10 seconds. Back to off, it’s on a again. I can still start my engine. What the hell is going on?

The anti theft security light should turn on(blink) only after you exit the car and lock all doors. I doubt the radio fuse has something to do with it.

Now that there’s no power to the radio, is the antitheft system sensing that as a theft?
