eCLIQ Control Key (C-Key)

The eCLIQ® Control Key (C-Key) manages the electronic communication provided by the eCLIQ® system.
It provides users secure access to the system software and the ability to transfer information between the software and cylinders.

Each eCLIQ® system must have at least one C-Key, referred to as the Master C-Key (MCK). The MCK is used to transfer information from eCLIQ® cylinders to the software and not to open them.
For systems with more than one administrator, it is possible to utilize additional C-Keys, also referred to as a Normal C-Key (NCK).
