Turn off Theft System on Cars

Some cars have an automatic theft system built in that can sometimes become activated without any threats. Here is how you can correct this problem without causing your battery to die.

Steps

Turning the Theft System Off from Inside the Car

  1. Check for a light on the dashboard. It will say System on "Theft System" or something similar.
  2. Make sure nothing is loose if you tried to take anything apart.
  3. Check to see if the battery has not been drained. At that point the car will not do any thing, except make a slight effort to start. If the battery is dead, ask someone to help jump start it for you.
  4. Place the key in the ignition, and turn it slightly to the right. This is also known as position 2, in which the car is on but the engine is off. This gives power to the necessary components to allow this method of bypassing the alarm to work. When you turn the key the Install a Satellite Radio Receiver in Your Vehicle should work, and the dash lights should light up.
  5. Keep the key that way for ten minutes, maybe a little more. The theft system light should turn off, and the car can be started.

Turning the Theft System Off Outside of the Car

  1. Insert the key in the driver's side door. Even if you have a keyless entry, you'll want to use the actual, physical car key and place it in the lock on the outside of the driver's side door.
  2. Turn the key and hold it. Turn the key so that you unlock the door, but hold it in place for several seconds. This can sometimes bypass the factory alarm and allow you to start the vehicle. This method lets the vehicle know that you have the actual key to the vehicle and in most cases will bypass in the even the key fob (the part that permits keyless entry) is broken, misplaced, or has a dead battery.
    • This method most commonly works in BMW's, Mercedes, and VW's.

Tips

  • This is just a slight problem with the theft system. Nothing is wrong with the car itself.

Warnings

  • Beware of some car dealers who use this method of fixing your car, then charge you extra.
  • This is only for the built in anti theft system, not other additional security systems.
  • Don't keep trying to start it until the system is deactivated. It will not start and your battery will die. Give at least 10 minutes before trying to start it again. If that was the problem it will start right up.
