The remote and key are two different things. When turning the key, you are searching for a good contact in the ignition switch. Cold weather just makes it worse to get a contact. Replace the ignition switch. The remote start. If it is after market. Take it out. Repair the wires. Soon it will die and won't let you start your vehicle. Then you will pay someone like me, that works at a shop, to tear it out and charge you $200 to do it. I just did one. A two minute fix, because I know. and a $200 bill. I got paid $1.5 to do it.
Hmmm, one thing to check is the plastic intake manifold bolts. These will tend to get loose, even loose enough to feel by hand. When the plastic intake manifold gets cold, it will contract, and with loose bolts, it will let cold air in there. Easiest bolts to check are near the firewall.
Check your Negative cable attatched to your starter. Next check your charge on your battery, a clicking noise indicates one of 2 things, 1. your battery is dead or dying and needs to be replaced, a battery charge will only solve the problem temporarily, it will continue to die and ruin your alternator. 2. your starter solenoid is going bad, being unable to deliver enough juice to your copper terminals surrounding the magnet that pushes the small gear pinion on to the flywheel and turns the motor to start.
The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Before the battery replacement the PCM was compensating for the lean condition, but with battery power disconnected for a period of time, the PCM is now running with default setting until it relearns.
