Car Won't Start Because of Anti-Theft System That Uses ...

Think the battery is dead. It is possible that the accident caused some damage to the wiring so that when you shut it down, the battery is being discharged.
Get battery charged and car running. then with car totally off hook up ammeter to battery and look for current draw. Then start removing fuses till you come across the circuit responsible for the draw and further troubleshoot that circuit for the offender. Till you find it leave fuse out so you can start car a few days later.

It should go without saying that it is IMPOSSIBLE to answer your question without first knowing the YEAR, MAKE, and MODEL of your vehicle.
That being said, I am 100% certain that your INERTIA SWITCH has triggered, and you merely need to push the reset button. (The inertia switch will trigger when there has been a collision, and disables your fuel pump to avoid a fuel leak that could start a fire.)

if your car has anti-theft on it when the battery went dead it signalled the computer that someone was trying to steal the car. you will have to reset the anti-theft system to start your car. if you don`t then recheck what you did changing the battery make sure all the wires are connected properly.

There is a reset switch on your car that has to be reset, It is under the dash on the passenger side right behind the dash pannel. Or it may be behind the foot pannel on the side of the car. There is a button that you have to push in order to reset the switch. There will be a red light come on when it is reset. Good luck.

Can you please detail it...

• 
  
• Your car probably have an immobiliser kit with the security system
• This cuts off the engine during a start under the hood
• This kills the power from the ignition point
• The keys may be code protected
• Check whether your security system is still active even if the doors are open!!
• Try to click the the unlock\ lock button simultaneously, when the doors are open
  
• Its better to remove the fuse of the security system and cut it off
  

TRY REPROGRAM KEY .PUT KEY IN IGNITION SWITCH TURN IGNITION SWITCH ON POSITION 20 SECONDS DONT START ENGINE WAIT 20 SECONDS TURN OFF SWITCH THEN TURN SWITCH BACK ON 20 SECONDS WATCH THE THEFT SECURITY LIGHT BLINKING.WHEN THEFT STOP BLINKING VECHICLE WILL CRANK.IF LIGHT STILL BLINKING.TRY FEW MORE TIMES KEY IN SWITCH ON POSITION FOR 20 SECONDS.MAKE SURE YOU HAVE THE CORRECT CAR KEYS IN SWITCH IF NOT WRONG SET OF CAR KEYS WILL SET OFF THEFT SECURITY SYSTEM.IF KEY RESETTING TRICK DONT WORK.CHECK BATTERY POWER MAKE SURE YOUR BATTERY HAS 12.5 VOLTS AND CHECK SECURITY THEFT FUSE.IF ALL LOOKS GOOD YOUR SECURITY HAS TO BE CHECKED OUT AT THE DEALERSHIP.

my friend you need a new battery or u have a poor battery cable connection, what is happening is due to low battery voltage, just because you recharged the battery DOES NOT mean the battery is any good..

To reset all codes in the car:
1. Turn the key on, but don't start it.
2. diconnect the POSITIVE battery turminal CAREFULLY!
3. wait 5 seconds, then turn key off.
4. reconnect the battery.
5. Try to start it.
Have u tried the battery, gas, oil, and trans fluid?

Is the car fitted with a collision battery-disconnect-switch? If so, it needs to be reset or replaced. I have no idea where it might be located, but probably near the battery itself.
