The anti-theft system is tied into main computer system, try disconnecting the neg battery terminal for about five minutes. if that doesnt work then it will have to be reset by the dealer

    you only need to remove the negative and it completely cuts the power. dealers usually charge between $25-50 for this

    no but you will still have to have them reset the computer because the anti theft system has probably locked it

Problem is in the {PAPS) anti-theft system.car wont start


I had the same problem - My car would not start. There is a bypass button in your car that when you press and start the car at the same time the car will start. To find this button look just above the hood release lever or in that area there is the bypass button. I finally had to remove the anti-theft system and now my car starts fine. The dealer would not replace the anti-theft, but could remove it but the cost was way to high, so I went to place were they replace car radio and other similiar services and payed around $30.00 to have it remove. They also told me that I really did not need this system on my car, because you can't start the car without the key.

Hope this help.

I need the radio security code for a 1999 cadillac sts


You will need to contact Cadillac service at your local dealership. Give them the serial number on the radio. They can then pull the anti theft lock code from their companies archive. The serial number on the radio is typically tied to a VIN, but since you bought just the part, they can't search that way. Hope that helps.

I repalaced the battery on my 2005 cadillac sts and the radio wont turn on is there a reset


Its that darn Anti-Theft feature that locks the unit and makes it useless to thieves. Any GM dealer can reset it for you. Not a user fix. There should be a procedure to temporarily disable the anti-theft feature before the battery is disconnected. Check the owners manual if you have it.

Starting disabled due to anti-theft system


Almost always the key is not at fault. I know for sure heat changes the resistance of the key but it does not happen as a usual thing you would have to apply physical heat. Contact me at albmahone@yahoo.com
