CyberLock is a “key-centric system” because the key is doing most of the work. It’s the CyberKey that is programmed with the permissions of what users may do: what locks they may open and the days and times they may open them.

What happens when a key touches a lock? When a key touches a lock, they communicate in a fraction of a second to determine if that key should open that lock: they exchange IDs, compare access codes, check to see if the lock ID is on the key’s list of authorized locks, confirm the key is there at the right time, and ensure the key is not on the lock’s list of lost keys. If everything checks out, the lock can be opened.
How are lost keys managed? There are two ways to manage lost keys:
proactively and reactively. When keys are first programmed for use, they can be set with an expiration date. Expirations are flexible and can be set according to the security required: hourly, daily, weekly, and monthly are common examples. When a key is lost, it may not be necessary to do anything if it expires at the end of the day. However, if the expiration is too far in the future to ensure your security, loading the lost key ID into the lock memory keeps the key from working.
