IF YOUR BATTERY DIES I found the answer to this under Alero 2002 security system will not let you start the car with out leaving key on for 10 minutes then you turn the key off then it will start?and this worked for me too. My battery went dead and after a boost and several other things the car would still not start. I then tried the above (key in the ignition and turned to the on position for 10 - 15 minutes or until "Security" stops flashing on the instrument cluster) and it started right away. I believe with the PASSLOCK II TM system the resistance of the key must be read before the car will start. Thanks for the advice DD
They seem to freeze a little in cold weather.

Spray no stick cooking spray(PAM) on the weather stripping for the door.
There is no power steering in a Mercury Villager at start up in cold weather due to a failing pump or low fluid. Fluid becomes much thicker in cold weather and is much harder to pump.
Your model should have a motor plug. If you plug it in to the wall outlet in cold weather overnight, you should have no problem to get it to start.
If a car won't start in cold weather it is possible that the valve guides have been worn. This often happens in cars that have been using ethanol as a primary fuel.
Many possible reasons. Maybe cold start switch(valve) is bad.
It means it is very hard to start and keep running in cold weather.
