I have a 2002 Monte Carlo SS 3800 series I have been having a problem with the security system it keeps going off as I'm driving down the road didn't know somebody had suggestions to help me with this

 

My security light was going off related to an ABS light going off. If you do not have any other issues it is likely a ignition lock cylinder issues ($86-110) for the part, and there are guides on the site and youtube to change it.

If that doesn't work it could be your Body Control Module which is much more expensive to fix, haven't done it but i think it is around 600+

 

Thank you xpage for the help it has helped alot thank you again
