Cylinder lock with the same key

A cylinder lock is a common type of lock. And a question we are often asked is whether there are cylinder locks that can all be opened with the same key. The answer is short and sweet: Yes.

Keyed alike lock can be used on almost any type of door

A cylinder lock with the same key is also called a keyed alike cylinder lock. This means that multiple locks can be opened with the same key. This is useful in situations where multiple doors or objects need to be secured with locks and the keys do not have to be changed every time. So you do not need to have a different key for each door. This applies to many types of doors, such as front doors, garden doors, garage doors and shed doors. A keyed alike lock provides a lot of convenience, because you only need 1 key to open or lock different doors.

Points to consider when ordering a new cylinder lock

When ordering a new cylinder lock, it is important to pay attention to a number of things. Firstly, it is important to choose the right size. Cylinder locks come in different sizes, depending on the thickness of the door or the object for which the lock is intended. Therefore, always carefully measure the dimensions of the old lock before ordering a new one. You can easily measure a cylinder lock yourself.

Choose the right type of cylinder

There are different types of cylinder locks available. There are cylinder locks with a single cylinder, but also with a double cylinder. A single cylinder can be opened with a key on the outside. This type of cylinder is also called a half cylinder . Do you only want to be able to open a lock on one side with a key and on the other side with a rotary knob? That is also possible. We also call this type a knob cylinder lock . With a double cylinder, also called a profile cylinder , a key is needed on both sides of the door to open the lock. This is safer, but can also be annoying if, for example, a door needs to be opened quickly.

Also replace the cylinder lock with the same key

In short, a cylinder lock with the same key certainly exists and can be useful in situations where multiple doors or objects need to be secured. It is also possible to replace and reorder a cylinder lock so that it connects to other existing cylinder locks in the home or business. We always require a certificate for your existing cylinder(s).

If you want to order a cylinder lock, it is advisable to go to a specialist such as Deur-Cilindervelden.nl. Do you need advice? No problem. You can call or email us with your question.

Frequently Asked Questions
Which cylinder lock do I need?

An SKG 3*** cylinder lock is the safest because this cylinder is equipped with core pulling protection. If the security fittings on your exterior door are equipped with core pulling protection, an SKG 2** cylinder will suffice. You can recognize the core pull protection in the door fittings by the rotating disc in front of the keyhole. If your front or back door fittings do not have core pulling protection, you can easily solve this by installing an SKG 3*** cylinder. In this way, the lock complies with current security standards to significantly reduce the risk of burglary.

What is an SKG-certified cylinder lock?

An SKG 2 star or SKG 3 star certified cylinder lock is equipped with a key that cannot be easily copied. You can only have the keys counterfeited upon presentation of the certificate. The advantage of this is that you can safely give your key to your employees or to your neighbors or your daughter's boyfriend. They cannot have the key counterfeited without your knowledge.

We always work with small systems, so that the key cannot be copied after a few years. This is the case with major brands such as Nemef and Lips.

What is a locking plan?

In addition to keyed alike cylinder locks, we can also help you with locking plans outside the webshop. These are systems where certain keys can only operate the designated cylinder locks and another key fits everything: the master key.

You can set up such a locking plan exactly as you want. If you contact us by email or telephone, we will advise you on drawing up a closing plan together. Of course, you can always drop by our store in Alkmaar.

How do I measure a cylinder lock?

The size of a cylinder is expressed in millimeters. It is actually the length of the cylinder divided into two with the screw hole in the middle in steps of five millimeters with a minimum length of 30/30: or 60 millimeters. If the door is four centimeters, the cylinder is automatically 60 millimeters long, so the cylinder protrudes ten millimeters on both sides. This is for the fitting that is still on the door.

From the basic size of 30/30, the cylinder can always be five millimeters longer on one side. A commonly sold size, for example, is 30/45, this size is used on new-build doors that are thickened by fifteen millimeters on one side.
