Such a random problem to ponder over!
Obviously locked using the handle. But key lock them for more security or keep them unlocked in case of a fire and can’t find a key?
DH says keep them unlocked - you can’t open them at all from the outside when the security locks are engaged with the handle. He’s worried we won’t find a key if there’s a fire.
I was going around locking and them unlocking them with the keys constantly but sort of coming to his thinking. Plus the keys were always falling out of the locks.
