Frequently Asked Questions
- What is an entrance function lockset?
An entrance lockset provides keyed access from the exterior side and free lever operation from the interior side. The exterior lever is locked and requires a key to operate, while the interior lever always provides free exit without requiring a key for emergency egress. - Why does this lockset come with three keys instead of two?
The Element™ entrance lockset is supplied with three keys per lock as standard, providing additional convenience for families or properties where multiple users require key access. This differs from some other Symmetry entrance locksets which supply two keys. - How does the OneCyl® system work with this lockset?
OneCyl® is Lockwood's exclusive cylinder assembly solution that allows cylinder interchangeability across the entire Symmetry range. This means you can replace or upgrade cylinders without replacing the entire lockset, enabling flexible keying arrangements and master key systems. - What is the difference between the three finish options?
Chrome Plate (CP) provides a bright reflective silver finish. Black (MBK) offers a contemporary matt black powdercoated aluminium appearance. Satin Chrome (SC) provides a brushed silver finish. All finishes are covered by the 5 year finish guarantee against tarnishing, discoloration, or corrosion. - Can I have multiple locks keyed alike?
This lockset is supplied keyed to differ as standard. For keyed alike or master keyed arrangements, restricted special keying systems are available. Contact your supplier for special keying options including master key systems and controlled key systems. - What is the adjustable backset and why does it matter?
The backset is the distance from the door edge to the centre of the door handle or lever. This lockset has an adjustable 60-70mm backset, allowing it to suit different door preparations. Always measure your door preparation before installation to ensure correct backset adjustment.
Additional Information
- Symmetry Range Integration:
This entrance lockset is part of the comprehensive Symmetry door furniture range. The Element™ lever profile provides contemporary styling suitable for modern residential interiors while coordinating with the broader Symmetry lockset family including passage, privacy, and dummy functions for consistent aesthetic appearance. - Entrance Function Operation:
The entrance function provides keyed locking from the exterior and free lever operation from the interior at all times. This ensures emergency egress capability while maintaining security control at the entry point. The latch bolt retracts when either the key is turned from outside or the lever is operated from inside. - Three Keys Standard:
Unlike many entrance locksets which supply two keys, the Element™ entrance lockset is supplied with three keys per lock as standard. This provides enhanced convenience for residential applications where multiple family members or users require independent key access without requiring additional key cutting immediately after installation. - Quality Construction:
Constructed from zinc alloy lever with steel chassis and zinc bolt head, combined with 5 pin Lockwood C4 brass cylinder assembly, this entrance lockset provides reliable performance suitable for residential applications. All materials are selected for durability and compliance with Australian Standards. - Tubular Latch Mechanism:
The 60-70mm adjustable tubular latch provides 13mm throw for positive door engagement. The D-strike includes an anti-rattle tab as standard, reducing noise and movement when the door is closed. The adjustable backset accommodates different door preparations without requiring additional components. - Australian Standards Compliance:
All Symmetry products are tested in accordance with Australian Standards for quality, security, and durability, ensuring reliable performance in Australian residential applications and compliance with local building requirements. - Cylinder and Keying Systems:
The 5 pin Lockwood C4 brass cylinder assembly is compatible with 6 pin systems and provides 78,000 key combinations. Standard supply is keyed to differ with three keys per lock. Key blank KB2015P is used for additional key cutting. Restricted special keying arrangements are available for projects requiring keyed alike or master keyed systems. - OneCyl® Cylinder Interchangeability:
The OneCyl® system allows cylinder assembly replacement across the Symmetry range without replacing entire locksets. This enables upgrading from standard keying to restricted keying, changing keying arrangements, or replacing worn cylinders while retaining existing door furniture and hardware. - Horizontal Mounting System:
The horizontal mounting screw fixing provides secure installation appropriate for entrance lockset applications. Installation requires door preparation for latch case, backset drilling, and strike installation. Professional installation is recommended to ensure correct operation and warranty compliance. - Black Finish Option:
The Black (MBK) finish provides a contemporary matt black powdercoated aluminium appearance suitable for modern architectural applications. This finish coordinates with black door hardware trends and is covered by the 5 year finish guarantee when properly installed and maintained. - Trade Pack and Display Pack Availability:
The Element™ entrance lockset is available in both trade pack and display pack configurations, providing flexibility for builders, developers, and retail customers. Trade packs offer economical bulk purchasing while display packs include retail-ready packaging. - Coordinated Door Furniture Systems:
For properties with multiple doors requiring different functions, this entrance lockset coordinates with Symmetry Element™ passage sets (hallways, non-locking doors), privacy sets (bathrooms, bedrooms), and dummy levers (inactive door panels) to provide consistent lever profile and finish throughout the property.
