Could be the crank position sensor...nothing to do with the anti-theft...have you tried dis-connecting the battery for 15 minutes? This is designed to re-set to factory specs...

How to reset anti-theft on a 2000 alero


The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Car doesn't crank is it battery, fuses or security tried to crank car din't hear starter but a lot of noises like clicling and sounds from fuil pump i think


Put the key on ACC. Does anti theft light up and stop? If it keep flashing while your cranking then it is the ANTI -THEFT. (by the way the humming noise ifs the fuel pump). If the anti theft doesnt light up during the cranking youll need the ignition module why I say that if it was crank position sensor the fuel pump wouldnt activate. your safe with the ignition module.and if you want it doesnt hurt to replace crank sensor why I say this the year.Its been a while just a suggestion

Car wont start, no clicks no sound


make sure you have power getting to your starter when you crank. check the small nut on the starter. should have 12 v or very close to it. this will tell you if your getting power to the starter or if somethign before the starter and something maybe with your anti theft system or not. its hard to say online cause of that anti theft. doest the light flash at all? the anti theft light?

if your getting power to the starter when you crank make sure your getting good power to the starter by turning on the head lights and see if they dim. a good starter will cause the headlites to dim when attempting to start. if nothing dims check connections. or assume bad starter motor. make sure your also getting power to the main starter stud as well.

good luck
