Mortise Locks

How to Choose Mortise Locks

Mortise locks are designed for doors that are prepped to accept a mortise lock body inside the edge of the door. Because this category includes keyed entry, passage, privacy, dummy, parts, and commercial options, the first step is choosing the function that matches how the door will be used.

Function is often the most important decision. A keyed entry mortise lock is used where security is needed, while passage, privacy, and dummy functions are designed for different interior or non-locking applications. If you are replacing existing hardware, matching the function first will help narrow the selection much faster.

It is also important to confirm the exact type of product you need. On this page, the assortment includes complete mortise locks, lock bodies, trim-related components, replacement parts, and commercial configurations. Two products may both fall under mortise locks but still serve very different purposes depending on what is already installed on the door.

Before ordering, check compatibility details carefully. Door preparation, handing, and application all matter with mortise hardware, especially when replacing an existing lock or selecting parts for a specific setup. Taking time to verify fit first will make it much easier to choose a mortise lock that works properly and installs as expected.
