I recently went to my truck to leave work. however when I turned the key in the ignition nothing happened. The everything went out except for the battery light, brake light, and airbag light. I hooked the scan tool up to it and did a seld diagnosis. A code came up for the anti theft system. B1845. Any ideal of how this occured and how to fix it?

Anti theft is working and that's why starter isn't engaging. This may work. Turn key on and leave on for 10 minutes. Turn off for 10 minutes. Turn on and wait for security light to go off. Then try to start car. This process works on most GM vehicles that have forgotten the key.
Good Evening, your anti-theft is in the ignition. If you go to start the car, then leave the key in the run position when it does not start for about 11- 15mins. Once the security light goes off then turn it off and try starting it. If it does not work you might have to do it a couple more times. What happens is the system relearns your key. Hope that helps, Thanks, Joey
if the theft light is was flashing on you, put the key in the ignition and turn all the way until the instrument cluster lights up, just don't start the car. leave it like that for aprox. 10 min. or until light goes out. when that happens, turn of(don't take out keys) and try to start car. hope it works.
very well could be due to anti theft issue. i don't recall the keys getting locked in the ignition from this though. try turning the key to the on postion- not cranking and leave it there for 15 min, then turn back off. do this three times. you may get a blinking light on the dash- don't worry about it. on the fourth try and start it. what you are doing is telling the alarm- i have the proper keys so let me take my car!
You may have a faulty ingition. Otherwise you have the very common GM anti-theft system. If you have a flashing anti-theft light with key in igniton, then this is what you should do:
Put key in ignition, turn to ON position (Do NOT Start) Leave in on position for EXACTLY 10 Minutes Then while watching the anti-theft light, as SOON as the light turns off after 10 minutes, START CAR IMMEDIATELY after light turns off.
