Instead, what matters most is whether it matches your needs – there are many models with different features depending on whether they should work outdoors or indoors, as well as what kind of locking system you prefer.

Mortise Lock vs Cylindrical Lock

Cylindrical Lock

While cylindrical locks tend to be much more common in residential homes, mortise locks are more commonly used for commercial applications. This is because mortise locks are a much more secure option for various reasons. A cylindrical lock is essentially just a small version of what you’d find on most modern-day doors.

The cylinder slides back and forth in order to unlock and lock. Though it may seem convenient at first glance, there is an inherent flaw with these types of locks; a key can easily be duplicated by an experienced locksmith or even off-the-shelf devices like those sold at any hardware store for under $30. In fact, it’s estimated that around 75% of all break-ins occur through unsecured windows or sliding glass doors.

This type of breach only takes seconds but has major consequences: almost 80% of burglars gain entry through these weak points before they ever pick up a crowbar to break down your front door! To avoid being next, consider installing new mortise locks on your home’s sliding glass doors and installing a solid wood door with multiple deadbolts instead.

Not only will doing so discourage potential intruders from breaking into your home, but research has shown that people tend to feel safer if their doors match up nicely with other doors in their neighborhood. They also help prevent excessive noise (as compared to hollow door frames) when someone knocks on your house while you’re trying to sleep or relax after work – a win-win situation!

Things To Consider Before Choosing A Mortise Lock

Installing a mortise lock is an important decision because they are essentially your first line of defence in keeping your home safe. You want a solid, reliable lock that is also easy to use. Before shopping for a new lock, consider these things: strength, installation and style. Here’s what you need to know before choosing a mortise door lock for your home Strength –


A strong lock is one of the most important considerations for selecting a good quality lock. Mortise locks are often made with either metal or plastic construction; there are many different types of metal options on today’s market, and each style has its own pros and cons. Metal locks tend to be stronger but can be more expensive; plastics don’t last as long as metals but tend to be lighter weight and easier to install. When choosing a door lock, make sure you select one that meets your security needs. If you live in an area where there’s lots of crime, you may want to go for something extremely secure.


Installation is another consideration when choosing a mortise lock; if you’re a DIY enthusiast, you may install your own mortise lock. This can save you some money, but there are some things you should look out for before taking on that job yourself. First of all, make sure you have all of the necessary tools and skills required; mortise locks can be difficult to install correctly without experience. If you do decide to hire someone else, take note of what they’re doing and ensure they’re using quality materials in their installation. Remember that lower prices might not always mean quality work—keep an eye out for unprofessional techniques or shoddy materials.


Consider your style and tastes when choosing a mortise lock. You’ll want a lock that looks great and fits in with your existing style, so it doesn’t stick out like a sore thumb! Consider all of your options before making a final decision; do some research online or speak with local suppliers about what’s available in today’s market. When you have an idea of what you like, make sure you pick something easy to clean, durable and resistant to wear and tear.

Handle Design

There are a few different handle designs that you can choose from when shopping for mortise locks; these include modern handles, lever handles and traditional latch designs. The handle design is not an important consideration in terms of security, but it does play a role in how easy it is to use your lock day-to-day. You should pick something that feels comfortable for you and your family members; everyone should be able to use their locks with ease and without any frustration or difficulty. If there are children or older people in your home, make sure you pick a style that’s easy for them to use as well!

How to Install Mortise Lock

Installing a mortise lock is not that difficult, but you should get help from an experienced person for it. First, you will need to measure your door size to know how long and wide it is. Make sure that whatever type of mortise lock you choose suits your door size. It should fit snugly in place but not too tightly so that it may cause problems while opening or closing the door. If there is an overhang, use wood fillers or putty on either side of the hinge plate to make sure it fits well and closes easily without making any noises when opened or closed.
