When it comes to securing your home, one of the most crucial components is the locking mechanism you choose for your doors. In Europe, one of the most popular types of lock design is the Euro Cylinder. However, not all Euro Cylinders are created equal. In this post, we’ll delve into the details of 1-star and 3-star Euro Cylinders, their security features, and some of the top brands on the market.

What are Euro Cylinders?

Euro Cylinders, also known as Euro profile cylinders, are a type of lock mechanism predominantly used in Europe. They’re characterized by their distinctive shape, similar to an enlarged keyhole, and are commonly used in conjunction with a Euro mortice lock case.

The cylinder operates as a self-contained unit that, when the key is inserted and turned, manipulates a revolving cam in the center of the cylinder, which in turn activates the lock mechanism. This design allows for easy replacement of the cylinder without needing to change the boltwork hardware.

1-Star vs. 3-Star Euro Cylinders

The star rating system for Euro Cylinders was developed by the Door & Hardware Federation (DHF) and the Glass and Glazing Federation (GGF) in the UK. It helps consumers understand the level of security offered by a particular cylinder.

1-Star Euro Cylinders

1-star Euro Cylinders offer a basic level of security and are typically less expensive than their 3-star counterparts. While they do provide protection against common breaking methods such as picking, drilling, and snapping, they lack advanced security features found in higher-rated cylinders.

3-Star Euro Cylinders

3-star Euro Cylinders represent the pinnacle of door lock security. They come equipped with advanced features such as anti-snap, anti-bump, and anti-drill mechanisms. These cylinders are designed to withstand even the most determined attacks, making them an excellent choice for those seeking superior home security.

Vulnerabilities of Low-Security Cylinders

Low-security Euro Cylinders, including many 1-star options, can be vulnerable to several types of attacks. These include:

  • Lock Snapping: This method involves applying force to the cylinder, causing it to break and expose the lock mechanism.
  • Lock Bumping: A specially cut key is inserted into the cylinder and then ‘bumped’ with a mallet or hammer. This forces the pins in the lock to jump, allowing the cylinder to be turned.
  • Lock Picking: Using specialized tools, an intruder can manipulate the pins inside the cylinder to unlock the door.

Top Brands and Their Offerings

Several renowned brands manufacture high-quality 1-star and 3-star Euro Cylinders. Here are a few noteworthy names:

  • Yale: Known for their reliability and durability, Yale offers a range of Euro Cylinders, including the 1-star Platinum Euro Cylinder and the 3-star AS Platinum Euro Cylinder.
  • ERA: ERA‘s range of Euro Cylinders includes the 1-star Fortress Euro Cylinder and the 3-star Fortress “British Standard” Euro Cylinder, both known for their excellent security features.
  • MUL-T-LOCK: Offering high-security solutions, MUL-T-LOCK’s Euro Cylinders, such as the MT5+ Euro Cylinder, are highly resistant to picking, drilling, and bumping.

The Cost of Upgrading

Upgrading from a 1-star to a 3-star Euro Cylinder will cost more initially, but it’s an investment in your home’s security. Prices vary based on the brand and specific product, but on average, you can expect to pay between £30 and £100 for a 3-star Euro Cylinder.


In conclusion, while 1-star Euro Cylinders offer a basic level of security, upgrading to a 3-star Euro Cylinder can significantly enhance your home’s protection. With advanced security features such as anti-snap, anti-bump, and anti-drill mechanisms, 3-star cylinders provide robust resistance to various types of attacks.

Remember, investing in high-quality door locks is an essential step in safeguarding your property. Consider your needs, budget, and the level of security you desire when choosing a Euro Cylinder for your home.
