What You Should Know About Mortise Locks

What You Should Know About Mortise Locks

The knob refers to the handle of the door you are working with; opening mortise locks should allow you to release the latch and push the door open.

We don’t blame you if you aren’t familiar with mortise locks. However, when you work as a professional locksmith, you should learn everything you can about them. You’ll encounter them whether you’re working on a commercial building or a private home. Here is more about what you should know about these locks.

Where You’ll Find Them

Mortise locks can be used for homes and other residential buildings. However, when you are out on a call, it’s more likely you’ll find such a lock on the doors of commercial buildings instead. These locks are highly resilient both against harsh weather conditions and attempts to break through them. Once you open them up for maintenance, you’ll notice that many of the inner workings are designed to be interchangeable. Not only does this make your job much easier, but it also means you’ll be able to complete repairs much more quickly and avoid making your customer wait.

Pieces of the Puzzle

You’ll know a mortise lock when you see it. The handle is much bigger than the ones on other locks, and you’ll also find deadbolts, lever trims, latches, and latch bolts. Here’s what else you should see when you start examining these locks:

  1. The body: The body of the lock is the casing that holds everything else together. By interacting with the body, you can also open and close the lock.
  2. The knob: The knob refers to the handle of the door you are working with; opening the lock should allow you to release the latch and push the door open.
  3. The cylinder: The cylinder keeps all of the inner workings of the lock safe. This piece is also what connects the door handles to the lock body.
  4. The spindle: The spindle attaches the door handle and the lock body to the door itself.
  5. The strike plate: Strike plates align the deadbolt on the lock with the bolt for the latch.

Now that you know what to look for let’s examine some upgrades that make mortise locks more effective.


Hard collars are one upgrade that will make your job a little bit more difficult. The reason for this is that these rings will make it harder for your tools to work. Once you work your way past the hard collars, you might spot the escutcheon plates. Escutcheon plates, also called rose plates, are upgrades that ensure the handle and cylinder fit together more snugly.
