Ahh. If they both don't work it could be the module that gets the signal from the remote maybe, but again coby will be able to tell you more about that when he gets back on

Your FOBs are obviously good. Also any door ajar, or door lock actuator malfunction. Make sure you didn't accidentally disable the start option in the menus.

I don't know for sure about the Cobalt but Malibu and G6 it's one of the menu items. It will read "Remote Start: ON" or "Remote Start; OFF" it should be "ON" Check your owners manual. What the hell....here are the pages from your owners manual. I will highlight in red the paragraph you need.

DIC Vehicle Personalization

Your vehicle has personalization capabilities that allow you to program certain features to a preferred setting. All of the features listed may not be available on your vehicle. Only the features available will be displayed on the DIC.

The default settings for the features were set when your vehicle left the factory, but may have been changed from their default state since that time.

To change feature settings, use the following procedure:

Entering Personalization Menu

Turn the ignition on while the vehicle is stopped.
To avoid excessive drain on the battery, it is recommended that the headlamps are turned off.

Press and hold the information and reset buttons at the same time for one second, then release to enter the personalization menu.
If the vehicle speed is greater than 2 mph (3 km/h), only the UNITS menu will be accessible.

Press the information button to scroll through the available personalization menu modes.
Press the reset button to scroll through the available settings for each mode.

If you do not make a selection within ten seconds, the display will go back to the previous information displayed.

Personalization Menu Modes
OIL LIFE RESET
When this feature is displayed, you can reset the engine oil life system. To reset the system, see Engine Oil Life System . See "OIL LIFE" under DIC Operation and Displays for more information.

See Tire Inspection and Rotation and DIC Warnings and Messages for more information.

Welcome to the forum, Helmet. I see you're already getting great input for members of the community here; unfortunately I'm limited in my abilities to troubleshoot being a customer service representative. However, let me know if you have any warranty questions, or if you decide to work with a dealership to get this checked into.

Unlock and lock your doors then check to see if all doors are locked. If you have a bad actuator the car won't start remotely because it falls into security mode. Technology is great but when it fails it can be a pain.

Just remembered if you have a pending code not necessarily a CEL your car will also not start remotely. So check for codes!

Just found this, it might help....

Remote Vehicle Start Inoperative
Diagnostic Instructions


Circuit/System Description
Remote vehicle start (RVS) begins as an RF message received by the remote control door lock receiver (RCDLR) from a keyless entry transmitter. The RVS request is sent by the RCDLR to the body control module (BCM) via serial data. The BCM monitors system conditions such as content theft deterrent (CTD), hood ajar status, and body DTCs to determine if an RVS event will occur. If conditions are determined to be acceptable, the RVS message is sent to the engine control module (ECM). The ECM monitors system conditions such as engine control parameters and vehicle theft deterrent (VTD) to determine if engine starting will be allowed. If conditions are acceptable, the ECM will initiate engine starting. During the engine run time in a RVS attempt, before the operator enters the vehicle, the ECM may discontinue engine operation if system conditions require it or a message is received from the BCM requesting the engine be turned OFF.

Diagnostic Aids
Important: If the vehicle has a current vehicle DTC that illuminates the malfunction indicator lamp (MIL), the cause of the DTC must be diagnosed before proceeding with the Remote Vehicle Start Inoperative diagnostic.

The RVS system will not operate if any of the following conditions are present:

• A current vehicle DTC that illuminates the malfunction indicator lamp (MIL)

• The vehicle is in valet mode.

• More than 2 remote starts have been attempted.

• The hazard switch is in the ON position.

• A current hazard switch DTC is set.

• The vehicle hood is ajar.

• A current hood ajar DTC is set.

• The CTD system detects an alarm trigger.

• Excessive engine RPM

• Excessive coolant temperature

• Accelerator pedal position greater than 0 percent

• Vehicle not in park

• Vehicle theft deterrent malfunction

• A current automatic transmission shift lock control system DTC is set.

• A vehicle speed sensor signal is detected by the ECM.
