Perfect for Our Apartment Complex

We ordered over 500 euro profile lock cylinders for a residential housing project. The quality is excellent — smooth key insertion, sturdy construction, and consistent keying. We especially liked the anti-bump protection and the customizable logo engraving. Will definitely reorder for future projects.

Smart Lock Compatible and Reliable

We integrated the GMB lock cylinder into our smart lock shell, and it worked flawlessly. The dimensions were precise, and the brass body feels durable. Our technical team was impressed with the master key support and quick delivery time. Great partner for OEM production.

Lock Cylinder FAQ

Q1: What is a lock cylinder and why is it important in a locking system?

A1: A lock cylinder is the central part of a locking mechanism where the key is inserted. It controls access by aligning internal pins when the correct key is used. The quality and type of lock cylinder determine how secure and tamper-resistant your lock system is, making it a critical component for both residential and commercial security.

Q2: What are the different types of lock cylinders available?

A2: The most common lock cylinder types include euro profile cylinders, single cylinders, double cylinders, and thumb turn cylinders. Euro profile cylinders are widely used in Europe and Asia, while thumb turn cylinders allow keyless operation from the inside. Each type serves different security, functional, and installation needs.

Q3: How do I choose the right lock cylinder for my door?

A3: To choose the right lock cylinder, consider your door thickness, lock type, security requirements, and usage scenario. Key factors include cylinder size (e.g. 60mm, 70mm), profile (euro, oval, mortise), material (solid brass, zinc alloy), and security features (anti-drill, anti-bump). For smart locks, verify compatibility with electronic shells.

Q4: What is the difference between a high security lock cylinder and a standard one?

A4: High security lock cylinders include advanced features like anti-snap, anti-drill, and anti-bump protection, and are often certified to EN1303 or ANSI Grade 1. Standard cylinders are suitable for basic residential use but may lack these protections. If your application involves high-traffic or high-risk areas, a high security model is recommended.

Q5: Are lock cylinders compatible with smart locks or digital door locks?

A5: Yes. Many euro profile lock cylinders are designed to fit inside smart lock housings. At GMB Hardware, we offer custom-tailored lock cylinders with specific dimensions, tailpiece types, and key configurations to ensure seamless integration with leading smart lock brands.

Q6: Can I order lock cylinders with the same key (keyed alike)?

A6: Absolutely. Keyed alike lock cylinders allow multiple locks to be opened with the same key, which is very convenient for homes, apartments, offices, or warehouses. We also support master key systems, where a master key opens multiple locks while each lock retains its own unique key.

Q7: How do I measure a lock cylinder for replacement or installation?

A7: To measure a euro profile lock cylinder, remove it from the door and measure from the center of the cam to each end (e.g. 30/30, 35/35 for a 70mm length). Always measure both sides, as some doors require offset sizes (e.g. 35/45). GMB offers custom lengths based on your exact dimensions and installation type.
