Lockwood Symmetry Series 1 Cylinder Assembly – 5-Pin Restricted Profile
The Lockwood Symmetry Series 1 Cylinder Assembly is a replacement cylinder component designed for use with Lockwood Symmetry knob and lever locksets. This cylinder accepts standard Lockwood C4 5-pin brass cylinders and supports 6-pin configurations, providing secure keying solutions for residential and commercial door hardware installations.
The cylinder assembly is compatible with the OneCyl interchangeable cylinder platform, allowing for simplified rekeying and master key system integration without replacing the entire lockset.

Frequently Asked Questions
- Will this cylinder fit my existing Lockwood lockset?
This cylinder is designed specifically for Lockwood Symmetry Series knob and lever locksets only. It is not compatible with other Lockwood series such as 001, 002, 3570, 3582, or non-Symmetry products. Verify your lockset is from the Symmetry range before ordering. - What does "restricted profile" mean for keying?
A restricted profile keying system limits key blank availability to authorised dealers and locksmiths, providing enhanced key control. Replacement keys cannot be cut at standard key cutting services and require authorisation from the registered key holder. This helps prevent unauthorised key duplication. - Can I rekey this cylinder myself or do I need a locksmith?
Rekeying Lockwood restricted profile cylinders requires specialised tools, pinning kits, and authorisation documentation. Professional locksmith service is required for rekeying operations. However, if your system uses OneCyl interchangeable cores, cylinder replacement can be performed by building maintenance staff with appropriate training. - What is the OneCyl system and how does it work?
OneCyl is Lockwood's interchangeable cylinder platform that allows cylinder cores to be removed and replaced without dismounting the entire lockset. This simplifies rekeying, reduces labour costs, and minimises building disruption during key system changes. A control key is required to remove and install OneCyl cores. - Why is this product sold in packs of 10?
Cylinder assemblies are typically required in quantity for multi-door installations, building fit-outs, or facility management operations where multiple locksets need cylinder replacement. The pack of 10 format provides cost efficiency for trade and bulk applications while ensuring finish and keying consistency across installations.
Additional Information
- Lockwood Symmetry Series Compatibility:
The Symmetry Series represents Lockwood's residential and light commercial door hardware range. This cylinder assembly is engineered specifically for Symmetry knob and lever locksets and is not cross-compatible with other Lockwood lock families. Attempting to fit this cylinder to non-Symmetry locksets will result in improper function and potential damage. - C4 Cylinder Platform:
The C4 designation refers to Lockwood's standard commercial cylinder format used across multiple product lines. C4 cylinders feature a 5-pin tumbler configuration as standard, with the mechanical capability to accept 6-pin configurations for enhanced security applications. The cylinder bore and spring chamber dimensions are standardised across the C4 platform. - Restricted Profile Key Control:
The 5-pin restricted profile (5RP) provides an additional layer of security through controlled key blank distribution. Key blanks are supplied only to registered dealers and locksmiths who maintain authorisation records. This system prevents casual key duplication but requires proper registration and documentation for legitimate key replacement needs. - Installation Considerations:
Installation requires removing the existing cylinder from the Symmetry lockset and installing the replacement cylinder using the horizontal mounting screws. Proper alignment of the cylinder tailpiece with the lockset mechanism is critical for correct operation. The cylinder must engage the bolt mechanism without binding or excessive play. - Master Keying and Keying Schedules:
These cylinders support master key system configurations where a hierarchy of key access is required. Master keying requires professional locksmith service to create appropriate pinning arrangements. For multi-building or complex facility applications, a formal keying schedule document should be maintained to track cylinder locations and key distribution. - OneCyl Interchangeable Core System:
The OneCyl system allows building operators to change locks without locksmith attendance by removing the cylinder core with a control key and installing a pre-keyed replacement core. This reduces rekeying costs and enables immediate response to security events such as lost keys or staff changes. The control key itself must be secured to prevent unauthorised cylinder removal. - Finish Matching:
Cylinder finish should match the existing Lockwood Symmetry lockset trim for aesthetic consistency. Chrome Plate finish is suitable for contemporary and commercial applications, while Polished Brass provides a traditional appearance. Finish does not affect mechanical function or security performance but may be subject to different warranty coverage periods. - Non-Returnable Policy Rationale:
Cylinder assemblies are non-returnable due to security protocols governing keyed components. Once a cylinder has left secure storage, it cannot be confirmed that key control has been maintained or that the cylinder has not been compromised. This policy protects both the end user and the distribution chain from potential security vulnerabilities. - Bulk Purchase and Project Pricing:
The pack of 10 format is designed for trade, contractor, and facility management applications. For larger projects requiring significant quantities, contact Gold Coast Hardware for project pricing and keying coordination services. Bulk orders can often be pre-keyed to a specific key code or master key system before dispatch.
