The security system prevents unauthorized operation of the car, your system has been tripped, and the car disabled. You will need to reset the security system to start it. If you have the original key you should be able to do it.
If the key for the Pontiac has a security chip in it as well, simply wait about fifteen minutes without doing anything and then your car should start. If the key does not have a security chip you may have to remove the battery to reset the system.
Clock & radio presets. Possibly the radio security code if the car is equipped with a security system on the radio.

To reset your car's security system, first, make sure all doors are closed and the key is removed from the ignition. Insert the key into the ignition and turn it to the "On" position without starting the engine. Wait for about 10-15 minutes until the security light goes off, then turn the key to the "Off" position and try starting the car again. If issues persist, consult your vehicle’s manual or a professional for assistance.

I am not sure about the mercury sable but my car does that also, 2003 Pontiac grand am gt, it tells you how to reset in owners manual. I have to turn the key to the on position, wait about 10 minutes and the security light in the dash starts blinking, when that happens...turn the key off and try to start it. Hope this helps
