What sort of locking mechanism will be used? I live in Canada and ride my bike all year round, in the rain, snow, sleet, below freezing temperatures, etc. Sometimes I have to leave my bike outside during the winter. I've had trouble opening my key operated lock before when it froze in the middle of the night... luckily I was able to get it open with rubbing alcohol and chain lube after about 20 minutes.

I'd be worried that this thing won't handle the weather, especially if its only battery operated (no key).

original poster here: all of the internal electronic components are water proofed and the battery operates under extended temperatures (currently the same batteries are used in north pole for remote sensing)

But if the water freezes inside and prevents the actuator from moving, then the lock won't work. the same can happen to the mechanical locks...if the water gets into the key hole and freezes there or freezes up the locking mechansim
