A mechanical master key system is expensive to run, because of its inflexibility in changing access rights and secure key management costs. Losing a master key means replacing mechanical cylinders and keys right across your facility. There's no shortcut.

How many replacement keys are lost and re-ordered each year with a mechanical key system?  Every lost key costs you time and money—and an instant replacement is impossible. Stolen or copied keys are also a constant security risk. No electronic audit trail is possible, and keys cannot be reprogrammed.

Using the Assa Abloy Aperio sytem it is easy to extend an existing access control system. Simply add Aperio battery-powered locks with integrated card readers to any door where the users want to upgrade security. Every door is linked to the access control system, and can be used with existing cards or a single digital credential—and without a wire in sight.

With Aperio, it takes a few seconds to issue or revoke cards, from a computer or a smartphone. Premises can be monitored and managed at any time of day or night. Simply reprogramme an RFID card and you have a new key—instantly. That is what Assa Abloy are calling the Aperio effect.
