The Best Mortise Lock: Our Picks
Guide: Questions you should ask yourself before buying a mortise lock
How does a mortise lock work?
With the help of a lever, the door handle or the key from the outside, the so-called latch, which keeps the door closed when it is unlocked, is moved in or out. When the handle is pressed down, it is retracted, and when it is released, it is retracted again and locks the door again. There are also mortise locks that have an additional locking function, as they are designed for external doors that need to be locked, for example.
The lock works in such a way that when the key is turned from the outside, first the bolt is unlocked and then automatically, when the door is unlocked, the latch is turned inwards by turning it, as with the handle mechanism, and the door can be opened.
Why do I need a mortise lock?
What alternatives are there to mortise locks?
As a second alternative, you can choose door locks with a combination of numbers. Here, no key is needed, but the correct combination of numbers must be entered in order for the door to open.
Decision: What types of mortise locks are there and which is the right one for you?
What distinguishes a mortise lock with a Buntbart hole and what are its advantages and disadvantages?
The low-priced Buntbart lock got its name from its appearance. While normal locks have a round head and go down narrowly, the Buntbart hole opens up towards the bottom like a semicircle, making it look as if the head of the key has a beard. Buntbart precedes beard because this lock can also be made in all variations or colours and shapes.
The disadvantage of the bearded lock is its low security standard, but that is why this mortise lock is used for interior room doors, where a high level of security does not normally have to be guaranteed. In addition, the Buntbart mortise lock cannot be installed in security doors, as it cannot provide smoke or fire protection.
What distinguishes a Chubb mortise lock and what are its advantages and disadvantages?
The Chubb mortise lock is a further development of the Buntbart lock. For the first time, the keys of the Chubb lock have been given several prongs at the bottom end and thus lift up small locking tumblers with the different lengths of the prongs and thus open or close the door.
The bolt of this mortise lock also allows the entire door to be locked by turning it twice, which works in exactly the same way as opening the locking tumblers. Since this type of mortise lock is no longer the most modern, as it usually has a very bulky key, it is no longer used on house or flat doors.
This was the case until about the 1960s, but it has been largely superseded by modern variants. In addition, there are further developments of the Chubb mortise lock, which is now used to lock safes or prison cells. However, these are only the latest models.
What distinguishes a mortise lock with a PZ hole and what are its advantages and disadvantages?
A mortise lock with a PZ perforation is the most common variant installed in Germany today.
PZ perforation or profile cylinder is also used for entrance doors. There are two different locking mechanisms for the cylinder lock. One is the keyed alike system or the keyed different system. There are also emergency and danger functions that ensure the door can be opened if the key is still inserted on one side.
It is also suitable for security doors, as it usually offers fire, drilling and smoke protection. With a mortise lock, however, special care must be taken to ensure that it is inserted correctly, as incorrect insertion or overhanging of the lock can lead to security problems.
In addition, you have to find out exactly which model you really need for a PZ hole because, as already mentioned, there are different functions and mechanisms that have different security standards. However, if you would like more detailed information on this, you are welcome to read the article on ABUS locking cylinders.
What distinguishes a mortise lock with a bathroom bolt and what are its advantages and disadvantages?
A mortise lock with a deadbolt is a key-free lock. The lock is opened with a knob that manually opens or closes the lock. This makes it easy to use in rooms that are often opened or closed during the day.
However, as this type does not offer a high standard of security, since the door can be opened from the outside with a flat object, this mortise lock with bathroom bolt is only used for bathrooms. Of course, it can also be fitted to other interior doors, but the normal case is the bathroom door.
Buying criteria: You can compare and evaluate a mortise lock based on these factors
Mortise locks can be made of different materials. Often, different elements of the mortise lock are made of different materials. Normally and one of the most secure materials is stainless steel. Often, entire mortise locks are made of stainless steel, but there are also variants where the bolt and the latch are made of metal. Zinc is also often found in mortise locks.
They are often made of a stainless steel core and a zinc shell. All in all, the most positive feedback is on stainless steel mortise locks, but metal locks can also be a secure option. However, if the mortise lock is made of a different material, which has not been mentioned so far, a second opinion or advice should be sought from a consultant shop.
The security of mortise locks is measured by the purpose for which the mortise lock can be used. As already described above, there are different types of mortise locks.
Accordingly, a mortise lock with PZ holes offers the highest security, while a mortise lock with a bathroom bolt could not avert a drilling incident or similar. The material of the mortise lock must also be taken into consideration, because a pure zinc lock cannot and is not as secure as one made of stainless steel. Therefore, before buying, it must be carefully considered for exactly which door the mortise lock has to be bought and what material it is made of.
The backset is a measurement that only exists for mortise locks. It is the distance from the centre of the keyhole and the square that secures the mortise lock to the outer edge of the mortise lock. Doors can have different backsets, so if you want to replace the mortise lock, it is important to measure the distance of the old lock in advance. A typical backset for solid doors is 65 mm. Since backset is always given in millimetres.
Before buying a mortise lock for your door, you need to know in advance whether the door is a DIN left-closing door or a DIN right-closing door. Here, you have to consider the direction in which the door opens.
The door is a DIN right-closing door if the door hinge is on the right from the point of view and therefore also opens to the right. This in turn means that the closing mechanism engages on the left-hand side. The other applies for DIN-left. Depending on what kind of door you have, you will then have to buy a DIN-right or DIN-left mortise lock.
Facts worth knowing about mortise locks
How do I open a mortise lock without a key?
A normal mortise lock can be opened with the help of a card, such as a credit card, identity card or similar. To do this, however, the door must not have been actively locked, but must only have fallen shut so that the latch has only closed the door. Then insert the card above the lock between the door and the door frame. Then slowly try to get the card close to the trap and slowly get it in between and then push the trap in.
With a little patience, you can open the door and save yourself an expensive locksmith.
