Not all doors are the same: Front house door and apartment doors have different security requirements than interior doors.
Depending on the area of application, different door locks are used on different doors at different positions in the house.
The use of Modern Mortise Locks
Today, mortise locks are mostly used which are pushed into a recess in the door – the so-called lock pocket.
In the past, however, box locks were also common, which were placed on the inside of the door.
Mortise locks can be divided into different types, including warded locks, cylinder locks, tumbler locks and tubular frame locks.
For interior doors, simple warded locks are usually sufficient. Their keys have a so-called beard, which can have different shapes.
It is possible that several locks can be unlocked with a single key. This is because there are only 64 different profiles in the US, according to Techpally.
If the key is lost, the lock can also be easily opened with a locking hook. You can find more advantages of smart door lock system like mortise locks.
External doors are usually equipped with cylinder locking systems.
As the name suggests, such locks have a separate locking cylinder in which various spring-loaded pins are located.
They ensure that each lock can only be opened with the appropriate key.
Removing a door lock without a key
Would you like to remove a cylinder lock that you don’t have a key for?
There are several ways to do this: If the door is closed, you can drill open the old lock.
It is best to use an HSS-E drill for this, as it is particularly hard.
Position the drill underneath the keyway and drill into the lock about halfway down.
This destroys the pins that lock the cylinder Now you can open the lock with the screwdriver as a key replacement. However, this method does not work for locks with anti-drill protection.
If the door you are trying to remove the lock from is already open, you can use heavy-duty pliers, such as water pump pliers, to remove the lock.
First remove the fittings on both sides of the door and loosen the screws.
Then put the pliers on the narrow side of the cylinder. Push it left and right hard until it finally breaks. After that you can remove all fragments from the door.
Play it safe with the new door lock
It is not always necessary to replace the entire door lock at once. If only the cylinder is defective, it is sufficient to replace it with a new one.
In any case, the new door lock should meet certain security requirements.
The security fitting should be adequately certified (VdS marking) and at least correspond to resistance class ES1 – even better: ES2 – (DIN 18257).
Attack resistance classes 1 and 2 (DIN 18252/DIN EN 15684) as well as drilling protection or drilling and pulling protection are recommended for locking cylinders.
In the case of entrance doors, the mortise lock should at least correspond to burglary protection class 4 (DIN 18251).
A secure front door also includes a robust strike plate, into which the latch of the door lock engages. The locking plate should also be anchored very firmly in the wall.
