Lately (we've had a cold snap in the last week)

I cant unlock the car (2001 Outback) with the remote first thing in the morning. By the time i get to work its fine and will work for the rest of the day.

It was fine last winter.

Anybody else ever had any issues like this?

Battery in the remote getting tired? Or lock mechanisms that need lubrication?

Battery is less than a year old.

Nothing happens when i push the button on the key. If it was mechanical, the blinker lights would still flash.

I found this while searching google
Rexnet Subaru Forums/Random Alarm & Central Locking Issue

The central locking on my L series has a mind of its own, but its a mechanical problem

Happened to my wife's Camry last week, all last week that specific door wouldnt lock/unlock, i gave it a squirt with sewing machine oil (clear thin runny oil) and worked as treat.
