Theft system light, what does it mean

Here's some of the dander on the web~ insert the key in the drives door lock. Go to Lock Back to unlock Back to Lock Back to Nuetral Back to Lock ..hold in that position for 5 seconds. then rotate back to unlock. Your theft light should now have gone out. You can start the car on a time per time basis using this procedure.

Thank you, I will try that.
