Twin Maximum Lock System

Developed in 2005 and released in 2006, this patented key system is offered through distribution as the next generation in patented key control. The standard system is UL 437 listed and offers a non-UL 437 version for areas that may not meet the criteria of a secure opening. This key system offers a number of options that enhance its use within your security network.

The Twin Maximum has the capability to be multiplexed; the number of sidebar combinations can accommodate key systems that exceed one million standard combinations. The most unique feature of the Twin Maximum is the interface ability it has with the ASSA Access Control C4 electromechanical key system.

You can add an audit control key and cylinder anywhere in your master key system to give you the latest in accountability of the use of that lock. The audit trail will give you the date and time the electronic key was used. This key will also operate as a mechanical key to open other locks that are not electric.
