You have not replace the pickup harness in the ignition switch, This is part of the barrel assembly, it actually reads the key. it has two wires in a yellow insulation sleave which connects from the barrel to a plug underdash. the other end to the plug has two wires in it that are purple, and white. which send the key resistance to the security module. you can bypass this wire harness if you can match the resistance from the key and hook it up to the purple and white wires under dash.

The security system has been activated. It's not able toread the chip in the key. That's y it only let it start 3 times. After that it locks up,put a battery charger on car and turn key on and leave on for 45 min,this will unlock anti theft module. Preferably use a spare key

Changed battery,now it won't start. Tells me anti theft system needs to be reset

Turn your key to ON, Not start, just to on. The theft light should start blinking. Let it blink until it stops. Could take up to 10 minutes or so, let it go until it stops. Then it should be reset.

'05 Chevy Malibu Wil Not Start

is the security light blinking on the dash? If so you need to rreprogram the key to the anti theft module. to do this, turn key to on...let sit for about 10 min or so until the security light flashes. turn key off.. count o 5. vehicle should start. if not then it will have to go to the dealer to have it specifically reprogrammed as the PCM and anti theft modules both no longer reconize the key code.

Yes, the key,ignition, or Theft Deterrent Module is not funtioning properly. You can start changing these out 1 by 1, or bypass the whole system for about the cost of a new key. This link explains and will help you.
