If the engine still has water in it and it is not leaking then replace the tempture sending unit. Just make sure that it is not running hot and make sure that the water is circulating it could also be needing a cooling system flush. But it is hard to say without seeing the car just make sure that the water level has not gone down and if it has a coolent recovery tank make sure that the hose that connects the tank to the radeator is not leaking and that the tank is also not leaking.

With the security system I have been told you can get a sensor that you plug into your security system that came standard with the car. THis system is located under the plastic that covers your speakers on the passenger side in the back. If you unplug the sensor and then pick up a relay from radio shack it acts the same as reading your key that is in your car and will allow you to roll the windows up or down when the key is in the ignition
