Generally speaking, if the security light is on and the engine will not crank, the VATS system is not reading the chip in the key.
Either the chip has failed, or the sensor in the lock cylinder, or the VATS module.
You could try a spare key but most times you have to have a shop make the repairs.

SOURCE: anti theft car wont start

have you disconnected the battery lately, or lost charge?  If so, dealer may need to reset the car.

SOURCE: dash says service anti theft system and wont start

Disconnect the batttery for 10 minutes, connect the battery and attempt to start, it will not start: do not turn the key off but leave in the on position, let the computer reprogram itself, the antitheft light will flash for 10 - 15 minutes, when it goes out; start you car, you are finished

SOURCE: is reading theft system and wont start

Try cleaning your key off... those keys have security chips and if you get the oily or dirt on them your car wont start. Or try using a spare key if you have one... Good Luck!

Clicking under the hood, dashboard lights keep flashing. Wont start!

Hello Vickie,

It sounds like your battery is dead, or if you're really lucky, your battery cables are corroded.
Pop your hood and inspect your cables at the battery, especially the Positive (Red) lead. If you see white oxidation build up, then the cables need to be removed and cleaned.
If clean, then the battery may be dead. It can be beyond its service life (sometimes there is a date code on the battery so you can determine age).
If the vehicle can be jump started; after starting, turn on heater fan and headlamps to high. If the lights are dim, then the alternator may be bad or is going bad.
Start with the battery first, then go from there.

Why wont my alarm reset in my 1998 chevy blazer the security system is killing the fuel and i cant get it to run it starts and dies imeaditly

I don't think the anti-theft is the problem.
On GM vehicles, the anti-theft system will not allow the engine to crank, or get fuel or spark. If it cranks, you have a different problem.

Whr is my fuel pump reset button on my 2003 grand am? Its security lock, it wont get any fuel. It cranks but wont start. Not getting any fuel. First time ever happening

There is no reset button.
The problem could be the anti-theft system which would knock out the injectors and spark to the plugs.
If the security light is staying on, the problem could be the chip in the key.

My theft light is flashing but my 1997 expedition wont start.The vehicle turns over but just don't start.

ANTI-THEFT SYSTEM Passive anti-theft system
Your ignition key has a unique imbedded transponder which engages engine electronics and allows the vehicle to be started. Without the use of your special ignition key, the vehicle will not start.

During each vehicle start, the coded key is read by the anti-theft system. If the key’s ID code matches the code in the anti-theft system, the vehicle is enabled to start.

Anti-theft system
Briefly illuminates when the ignition is turned to the ON position to verify that the passive anti-theft system is operating properly.

Also, its possisble that tou have actovated the fuel pump switch.

CHeck it.
