In version 2.5.2+ locks can be created to auto reset on a regular basis (maximum of 20 times). An auto reset acts like a keyholder reset which will reset all card counts to the number the lock started with. Auto reset locks are only available on variable locks.
You can choose how often a lock should reset i.e. every 8 hours, or every 7 days. And you can set the maximum number of resets before the auto resetting stops. No more than 20.
