It is -10 in our unheated garage with a temperature of -30 Celsius outside.
It seems like the deadbolt is either freezing up or maybe having battery issues? I am thinking it’s more of freezing up it will not lock even though the keypad works. I cannot even manually lock the deadbolt at the back.
Should I try engineer lithium batteries rated for -40 Celsius or is this more of the lock not working in -10 C?
