(Door) cylinders

Door cylinders are an essential part of your home’s security. They form the core of any lock and are crucial for the proper functioning of your doors. Whether you're moving into a new home, replacing your current locks, or need an extra key, choosing the right door cylinder is important. Our range includes a wide selection of cylinders, from standard models to those with advanced security features. We offer cylinders from top brands known for their reliability and durability. Whether you're looking for a single cylinder, double cylinder, or thumbturn cylinder, we've got you covered.

Different Types of Cylinders

There are several types of cylinders available, each with its own features and levels of security. Here’s an overview of the most common types:

• Single cylinders: Ideal for doors where you only need a key on one side.
• Double cylinders: Can be operated with a key from both sides.
• Thumbturn cylinders: Feature a turn knob on the inside, convenient for quickly locking the door without a key.

Cylinder Security Ratings

Cylinder security is often indicated by the SKG certification. SKG stands for “Stichting Kwaliteit Gevelbouw” (Dutch quality assurance institute):

• SKG★ (1 star): Standard burglary protection.
• SKG★★ (2 stars): Offers drill protection against common break-in methods like drilling.
• SKG★★★ (3 stars): Highest level of protection with features like anti-core pulling and resistance against advanced burglary techniques.

Keyed Alike Cylinders

For added convenience, you can choose keyed alike cylinders. This allows you to open multiple doors with a single key, ideal for homes and commercial properties. These sets can always be expanded with additional cylinders.
When selecting the right cylinder, don’t just consider the price, quality and security level are equally important. Our experts are happy to provide personalized advice and can perform a competitor analysis to recommend the best options.

FAQ: Frequently Asked Questions About Door Cylinders

1. What is the difference between a door cylinder and a cylinder lock?

A door cylinder is the part of the lock where you insert the key. The cylinder lock includes both the cylinder and the mechanical parts that operate the lock. Though often mentioned together, they are technically separate components.

2. How do I measure a door cylinder correctly?

Measure from the center of the set screw to the left and right in millimeters. Also, check whether the door has hardware with anti-core pulling protection, this can affect the cylinder size. Visit our page “Measuring a Door Cylinder” for a clear explanation.

3. What is anti-core pulling protection and do I need it?

Anti-core pulling protection prevents burglars from pulling the cylinder out of the lock using a screw or puller. It is mandatory in many new homes. We always recommend SKG★★★ cylinders with anti-core pulling protection for exterior doors.

4. Can I replace a door cylinder myself?

Yes, in most cases it’s easy to do with just a screwdriver. Just make sure you choose the correct cylinder size. Our customer service is happy to help if you’re unsure.

5. What are keyed alike cylinders and why choose them?

Keyed alike cylinders allow you to open multiple doors with the same key. Ideal for front doors, back doors, and sheds, or for businesses that need one key for multiple access points.

6. Are certified cylinders more secure?

Yes, certified cylinders offer not only physical protection, but also prevent unauthorized key duplication. Extra keys can only be made upon presentation of the security certificate.
