Smart Lock Battery Draining Too Fast — Rotterdam, Zuid-Holland

A smart lock that drains batteries in weeks instead of months usually points to a mechanical or connectivity problem, not defective batteries. Misaligned strike plates force the motor to strain on every lock cycle, and a weak Bluetooth or Z-Wave signal causes the lock to retry connections repeatedly, both of which consume far more power than normal. A smart-home installer can realign the door hardware, verify signal strength from the hub, update the lock firmware, and adjust auto-lock timing to extend battery life back to the manufacturer's rated span.
