Does it happen only after UNLOCKING THE DOOR WITH A KEY, if so read this tsb, click here, it may be DUE TO MOISTURE ENTERING INTO THE ANTI-THEFT SWITCH.

If that message appears when not using the key, read this article, click here, Content Theft Deterrent (CTD) Alarm Mode Inoperative.

Plus this, click here, Diagnostic System Check - Theft Deterrent. Also, this article, click here, on Content Theft Deterrent (CTD) Will Not Arm.

Using a scan tool perform all the steps to test the operation of the Theft Deterrent System.

It happens when using the key. I use the key because the electronic key wont work so I have to unlock the car by using the metal key. I unlock the door and no alarm , but as soon as I start up the car the factory alarm goes off and I use the electronic key with the unlock button to stop the alarm. on the screen it keeps displaying" Theft system Problem Car May not restart" I do not know what to do. Autozone said they can not use there scan tool because their is no maintenance lights on, so what scan tool and where can I get it and please send me that other link that would not work.

Ok, sorry, click here. If only when using the key than maybe there is moisture in the anti-theft switch like that first tsb says.

They must be having problems with those switches, I see they have been superseded again.

Plus they are cheaper here.
