A mechanical pushbutton lock works entirely on springs and levers, so it has no batteries, no wiring and nothing to replace annually. It cannot lose power because it never had any.
How to choose
What actually decides the part number
Where they winGates, plant rooms and storage. Anywhere running power is expensive and a dead battery is worse than a lost key.
