Why does my 2000 lesabre need 2 remote entry keys when cold and why does my clock not work or my compas????

I don't quite understand your question about needing two remote entry keys when cold..If you are saying you have to hit the remote unlock button twice to unlock the door you have a weak door lock actuator the first time you push the button it moves part way the when you push the button again it moves the rest of the way and unlocks ( not uncommon for these vehicles) does the compass display at all or is it just incorrect ??

Batteries are affected by cold temperature.
Just like a car battery won't have enough power to turn engine when battery gets weak and it's cold outside.
I'm guess your remote is stored outside in cold garage.
See if remote battery can be replaced with fresh one.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

On the rear of the motor unit you will find the up and down force adjustments. Increase these just about 1/4 turn and try. Make sure the tracks have not been lubricated at some time with grease. With the cold weather the grease becomes thick. The tracks should never be greased.
