Battery Notifications/monitoring
A live battery status is shown in the digital keys management software (please see section 2
User guide for more information). Account administrators can set up email notifications for when
battery status gets below 10%.
Care and maintenance
The NB IoT smart locks LDK400 are maintenance-free. At no time may they be oiled or greased
with lubricants containing mineral oil. Cleaning may only be carried out with non-stick, residue-
free cleaning and disinfection agents. No abrasive cleaning agents, or acids may be used for
care and maintenance. Equally, pressure washers may not be used. Although the LDK400 is
weatherproof we don
’t suggest the use of a high pressure hose to spray product, as it can lead
to damage and liability exclusion.
Metal Key override
Each lock is delivered with a standard mortise lock cylinder (EU/AU) and other countries
compatible. The cylinder can be replaced with most other cylinders. We recommend the use of
metal keys in the case of emergencies. Use of metal keys will not show up in the lock events
audit trail.
