We need to run through the disarm process to try and get that light to turn off.

That means we need to use the key fob and unlock the doors, the key to unlock the driver door, or the key needs to be put in the ignition and turned to the on position for up to 30 minutes.

Here is a guide that will help with this issue:

If all this fails then we need to check codes and see what is there.
