Guide: Questions to consider before buying a security lock
What is a safety lock?
Security lock is a generic term for different types of locking cylinders. Security locks are located in house entrance doors as well as in apartment doors and serve to protect property.
Since the front door, next to the windows, is probably the first point of contact for burglars, it is essential to choose the right security lock. The lock thus not only serves for security, but also conveys a feeling of well-being.
Besides the protection, the aesthetic aspect of a lock should not be neglected. In a beautiful living environment, the lock cylinder also serves as an optical embellishment.
To ensure optimum safety, the door must also meet safety criteria. Even the best lock in the world is only as strong as the surrounding door.
Security locks are divided into different security categories and are standardized according to DIN.
By the way, so-called armoured bolts also help to secure the door.
What does a security lock cost?
There is a wide price range between the different security locks. Depending on the quality and size of the cylinders, the cost varies. The range can be from about 20 to 100 Euros.
Cheap security locks start at 20 Euro, but of course you should keep in mind that small cylinders are cheaper than large ones, and low security levels are cheaper than very secure cylinders. Other factors that influence the price are cylinder brand, cylinder type and materials.
Who pays for the safety lock?
Who pays for the damage in case of a defective lock? Landlord or tenant?
That depends. If you as a tenant have wilfully, i.e. intentionally, destroyed the lock, you must also pay for the damage caused. But that will happen very rarely.
The civil code §538 regulates who is liable in case of a defect. A security lock is a mechanical component and will wear out sooner or later. This means it will have to be replaced at some point, even under normal use. This is therefore not the responsibility of the tenant, which means that the landlord has to pay for the change.
Where can I buy a security lock?
Security locks are available in specialist shops and department stores, as well as in many online shops. Additionally, it is possible to order security locks directly from your local locksmith.
According to our research, most security locks are sold through these online shops:
All security locks that we present to you on our site have a link to at least one of these shops. If you have found a suitable cylinder that you like, you can strike right away.
How do I measure the size for a security lock?
To order and change a security lock, you must of course first think about the right size. Therefore, I will explain to you here how to determine the correct cylinder size.
You can measure with a standard folding rule. It is important to know that there are two dimensions to be determined: the inner dimension (from the centre to the inside of the room) and the outer dimension (from the centre to the outside of the room).
Both dimensions are determined from the cylinder centre or alternatively can be measured from the fixing screw. The outer dimension is always on the left and the inner dimension is always on the right.
The basic length for profile cylinders and knob cylinders is always 30/3
Have you determined your cylinder dimensions? Congratulations, you can now proceed to the selection of your security lock.
Decision: What types of security locks are there and which one is right for you?
If you want to get a security lock, there are different types of cylinders that are suitable for different applications.
- Double cylinder
- Knob cylinder
- Half Cylinder
- Lever cylinder
With the following section we would like to help you to make your decision easier so that you buy the security lock that suits you best.
What is a double cylinder and when is it used?
The double cylinder is probably the most common cylinder. It can be locked from outside and inside with a key. The double cylinder is also available with the emergency and danger function, which means it can also be used if the key is inserted from one side.
Suitable for: front doors, cellar doors, apartment doors
can be operated on both sides
emergency and danger function
Inside only lockable with key
Key loss usually expensive
What is a knob cylinder and when is it used?
The knob cylinder can only be locked from one side with the key. There is a knob on the other side (inside). Therefore this variant can always be locked from the inside and no key is required.
Suitable for: front doors, cellar doors, apartment doors
easy to close on the inside
Not suitable for doors with glass
lower security than double cylinders
What is a half cylinder and when is it used?
The half cylinder can only be locked on one side with the key (outside). It cannot be locked from the inside. The length is always 10mm on the inside and is different for the outside, depending on requirements.
Suitable for: Mailboxes, garage doors etc.
Not lockable on the inside
lower safety level
What is a lever cylinder and when is it used?
The lever cylinder is, as the name suggests, equipped with a lever on one side. It opens and closes by means of this lever and is available in a wide variety of variations. However, it is the exception and is rarely used.
Suitable for: Lockers, mailboxes, boxes
Only suitable for simple protection
few application possibilities
Purchase criteria: You can compare and evaluate security locks based on these factors
In the following we will show you on the basis of which aspects you can decide between the multitude of possible security locks.
The criteria you can use to compare the cylinders include
- Security level
- Product dimensions
- Overall length
- Number of keys
In the following paragraphs we will explain what is important for the individual criteria.
An important criterion for delimiting locking cylinders is of course the guaranteed security. Every security lock can be divided into different security levels, depending on the nature of the materials used and the processing.
Usually security locks of level 1-3 are used.
Cylinders with 5 to 6 so-called internal pins are classified in security level 1. They are used for low to medium security requirements, for example for garage doors, letterboxes or similar.
Cylinders which also have 5 to 6 internal pins are classified in security level 2. The difference, however, is that they provide additional security by scanning the key from the side.
Alternatively, they can also be provided with drilling protection. They are used for medium security requirements, for example garage doors with access to the house or a side entrance.
Cylinders that use at least 6-9 internal pins are classified as security level 3. Other security mechanisms are used for this lock to ensure the high security level.
Highest drilling protection, as well as protection against pulling out or chiselling in is available here. They are used for high security requirements, for example for homes, office complexes or industrial plants.
Note: Be very careful when selecting the security level. A security level that is too low provides a target for burglary.
Of course the product dimensions of your cylinder play a role. The dimensions are determined by the door in which the security lock is to be installed. We have already explained above how to determine the correct dimensions.
The length of the cylinder also depends on your door. The overall length depends on the thickness of your door. This means that the overall length must be as large as the width of your door.
Number of keys
The number of keys of your cylinder usually depends on how many people should have access to the lock.
If your security lock is to be used for an entrance door of a detached house, the number of keys usually depends on the number of occupants. For a garden shed, for example, fewer keys are usually needed, since the fluctuation is not so high.
If your selected cylinder does not have the necessary number of keys, this is usually not a problem at all. Make sure that a security card is included in the delivery and you can have other keys copied by your local locksmith or have the manufacturer send them to you.
Since the security lock is not only for security, but also has to serve aesthetic aspects, you should of course think about the colour of the lock.
It is important that your lock matches the colour of your door and fits harmoniously into the overall picture.
Trivia: Worth knowing facts about security locks
What should I do if I lose the key to a security lock?
The loss of a key can be very annoying and above all also expensive, according to the German Key Insurance, a key is lost every 35 minutes in Germany.
However, it is important to distinguish what kind of key you lose. Usually the locking system is replaced after the loss, as it cannot be guaranteed that the required security is still guaranteed.
In any case you must inform your landlord immediately, as you are not allowed to have a duplicate key made without the permission of the tenant.
Who bears the costs of the loss?
If the tenant is responsible for the loss of the key, he is also obliged to bear the costs of the replacement. The lessor is entitled to have the lock changed against reimbursement of the costs.
So that you can feel safe despite losing the key, an alarm system, an electronic watchdog or even a motion detector would be an advantage. In addition, window locks are extremely useful to protect your apartment or house from burglary.
