The ASSA CLIQ system provides encrypted access control data in an electromechanical key that will communicate with a miniature servo-motor within the CLIQ cylinder. C4 CLIQ cylinders retrofit standard mortise, rim, and cylindrical locksets. They can be programmed with time zones and provide an audit trail for 1,000 events. The CLIQ key may be cut to work in mechanical Twin Maximum high security key systems. Contact your ASSA service center or dealer for more details.
