Cyberlock works as electronic cylinders replace standard mechanical cylinders, no wiring or battery required at the lock.
Cyberlock cannot be picked and also can not be duplicated. for each key contains a list of locks it can open with days and times. Keys can be assigned a begin date and expiration date.
A record of all events is stored in both the locks and the keys. One key opens doorway, padlock, cabinets, safes, vending machines and more.
