Important Ordering Notes

If you are ordering 2 or more units of the same size but require different keys for each package, please contact our customer service team before your order ships. If no special instruction is provided, all same-size cylinders in a single order will default to being keyed alike (operating with the same key).

Installation Tips

Before purchasing, measure your existing lock cylinder from end to end to confirm the correct size (60mm, 70mm, or 80mm). Ensure your door thickness falls within the 35–45mm range. Standard flathead and Phillips screwdrivers are all that's typically needed for installation.

Frequently Asked Questions

Q: What does "keyed alike" mean for this brass lock cylinder?

A: "Keyed alike" means that multiple lock cylinders are all operated by the same key. This is ideal for homes or offices where you want one key to open several doors, eliminating the need to carry multiple keys. When ordering, simply specify the keyed alike option and all cylinders in your order will be matched to a single key pattern.

Q: Which size brass lock cylinder do I need — 60mm, 70mm, or 80mm?

A: To find the right size, remove your existing lock cylinder and measure it from one end to the other (total length). Common sizes are 60mm for shorter door profiles, 70mm for standard doors, and 80mm for thicker or double-door applications. All sizes fit doors with a thickness of 35–45mm.

Q: Can this lock cylinder be used for outdoor doors?

A: Yes. The solid brass construction and brushed finish are designed to withstand outdoor conditions, including exposure to moisture and temperature changes, making it suitable for both indoor and exterior door applications.

Q: Is a master key system available with this cylinder?

A: Yes. This lock cylinder is compatible with master key configurations, making it a great choice for landlords, property managers, or businesses that need one master key to access multiple entry points while individual keys still work for each specific door.

Q: How many keys are included with each lock cylinder?

A: Each lock cylinder package includes keys. The exact number of keys included may vary by variant — please check the specific product listing option you select or contact customer service for details.
