A mortise lock

A mortise lock is a very specific kind of lock containing a handle and lock set. Depending on where you buy it, you could buy a lever and tumbler style lock in the UK and in Europe, but in the US you are more likely to buy a cylindrical style lock as it is considered to be more secure.

You cannot just attach a mortise lockset to the door. It has to be cut into the panel into which it is to be fitted. The lock comes in a number of parts i.e. the lock body which is the bit you put inside the panel of the door, the lock trim i.e. the doorknob, handle or lever depending on the style you choose, the strike plate which is also known as the box keep. When the door is locked the bolt is inserted into the hole in the frame and it is the strike plate that keeps this aligned. The final part of the lock is the keyed cylinder which as the name suggests operates the actual locking and unlocking mechanism. When you open the door and look at it, you will see a solid metal plate securely screwed into place that is flush with the frame.

It used to be the case that a mortise lock was only found on older buildings as the bored cylindrical locks were more popular. This was partly to do with the fact that it takes a certain set of skills to install the former type of lock. However in recent years, the mortise has found a new following especially in the more up market houses primarily because it provides better security. It can also be found on modern commercial buildings for the same reason. There are a number of brand names associated with this type of lock, one of the most popular being the Sargent mortise locks. Schlange, Baldwin and Yale are some other popular providers.

Can you fit one of these types of locks yourself? Well yes if you have good carpentry skills but for most people you should employ a qualified locksmith or carpenter with experience in fitting this style. As it has to be fitted into the actual door as opposed to attached on top of the panel, you can do a lot of damage to the wood never mind end up with a lock that is not aligned properly if you do not know what you are doing. If you are fitting an exterior mortise lock to a steel door perhaps in a commercial building, you will need an expert used to fitting this additional security measure.

Although some people say that installing a mortise lock weakens the door, and they are probably correct as you have interfered with the original timber setting, it actually improves the security of your home making it more difficult for burglaries to break in. If you fit these types of locks to your home you should tell your insurance company or broker as you may find that you qualify for a discount on your home insurance premiums.

In addition to providing more security, the availability of various different styles of mortise lock furniture has accounted for the increase in popularity. There are a range of door knobs you can purchase including if you prefer an antique mortise lock, if you were restoring an old property to its former glory. Mortise door hardware comes in polished brass, satin nickel, polished chrome and antique brass so no matter what your personal taste is or the design of your home, you are bound to find the right style for you. If you live in an area prone to adverse weather, you may have been advised to install some mortise storm door hardware.

Up until now you may have taken locks for granted. In fairness most of us have busy and interesting lives and up until recently the security measures you employ at home were not usually the topic of conversation at the dinner table. Unfortunately with the current economic crisis and resulting rise in petty crimes and burglaries, all of us are becoming more concerned. Perhaps you have already had your home broken into and are trying to secure it more effectively to prevent a reoccurrence.

Some people are investing in firearms and safes for the first time while others are employing locksmiths and woodworkers to install a mortise lock on their external door. The in built heavy duty deadbolt helps to make us all feel more secure. If you want a deadbolt with a cylindrical lockset, you will need to install a separate deadbolt lock which means drilling more holes in your door.

A mortise lock is an investment – it will improve the security and look of your home but it comes at a price. There are many fantastic deals you can choose from so be sure to shop around to get the best based on your personal choice and requirements.
