Is there still a viable reason to specify and select 5-pin cylinders?

The Illusion of 5-Pin Cylinders

At first glance, five pins in a lock cylinder may sound impressive. With a bit of clever marketing, it’s easy to see why buyers believe they’re getting solid security. In the past, this may have been true. But things have changed significantly in recent years. It’s time for those still promoting 5-pin cylinders to acknowledge the truth – this outdated, inferior product has no place in modern security.

The True Cost of Cheap Cylinders

5-pin cylinders are often sold on price, but like many so-called bargains, the true cost can be far greater. If you replace a lock cylinder in your home, and your insurance policy requires specific standards, you could unintentionally void your cover. This is an easy mistake to make – after all, who reads the fine print on insurance documents?

Insurers’ Standards and Vulnerabilities

Insurers, of course, set their premiums to reflect their risk. In the case of lock cylinders, they often specify BS3621. Under this standard, cylinders must be 6-pin models to achieve the minimum specification. Insurers are well aware that the 5-pin versions are more vulnerable to attack.

The Impact of Approved Document Q

In 2015, a new requirement, Approved Document Q, dealing with the security of dwellings, was added to English Building Regulations. For the first time, new dwellings were required to be able to resist unauthorised entry by casual or opportunist burglars. Manufacturers rushed to ensure their products reached the required standards. PAS24 is often-quoted as the standard for door security, and let’s be absolutely clear: to meet PAS24, a 6-pin cylinder is required as a minimum necessity.

Limitations in Complex Systems

Beyond the domestic market, the limitations of 5-pin cylinders become clear. Their design offers fewer combinations than a 6-pin cylinder, making them unsuitable for complex masterkey systems, such as those used in hospitals and schools. Specifiers often find themselves facing difficulties when trying to meet their client’s keying requirements. What was initially specified may not work, leading to the need to switch to a 6-pin solution. While this adds to the cost, it’s often the only option to achieve the desired keying complexity.

Security Features and Compliance

With fewer chambers in a 5-pin cylinder, the options for enhanced security features are limited. For example, construction keying isn’t usually a possibility. Also – with implications that most consumers will understand – fewer chambers means no anti-bump features. If you don’t have anti-bump capability the cylinder cannot be considered for use on entrance doors to dwellings – again as part of Approved Document Q. Furthermore, without anti-bump it’s not possible to achieve the much-publicised 3-star security rating. The result – properties are more vulnerable to attack.

The Future of Lock Security

The good news is that, overall, both in the domestic and commercial markets, standards of security are increasing. Lock cylinders are better designed and built, more door manufacturers are choosing 3-star products and there is an increased understanding that for total security, key systems need patent protection.

The Persistent Problem of 5-Pin Cylinders

The bad news is that some vendors continue to push 5-pin cylinders onto unsuspecting buyers. Surely, it is time this stopped.

Why it pays off to invest in mechatronic or electronic security technology

Security has moved on. Traditional mechanical cylinders still have their place, but today’s buildings demand more: greater control, better auditability, remote management, and future-ready flexibility. That’s where mechatronic and electronic security technology delivers measurable value. One standout example is the TOKOZ ePRO mechatronic cylinder, a solution that intelligently blends mechanical robustness with electronic access control. It represents a smart evolution rather than a wholesale replacement of proven mechanical security. What is Mechatronic Security? Mechatronic security combines: The result? A cylinder that looks and installs like a traditional euro profile lock, but operates within a controlled electronic ecosystem. The TOKOZ ePRO Advantage The TOKOZ ePRO cylinder functions like a standard euro profile cylinder, meaning: Installation is straightforward, with no radical door modifications required, making it ideal for retrofit projects as well as new builds. But beyond mechanical familiarity lies its real strength: electronic access control embedded inside a secure cylinder platform. Why investing in Mechatronic Technology pays off 1. Enhanced access control without replacing every door With mechanical-only systems, lost keys often mean expensive cylinder changes. With mechatronic systems: This dramatically reduces long-term operational costs. 2. Full audit trail and accountability Traditional keys leave no record. Mechatronic cylinders provide: For commercial, healthcare, education, and multi-occupancy buildings, this level of oversight is increasingly essential for compliance and risk management. 3. Flexibility for changing environments Buildings evolve. Staff change. Tenants rotate. Security requirements increase. The TOKOZ ePRO system allows: This adaptability ensures the system continues to deliver value long after installation. 4. Retaining mechanical security strength One common concern with electronic systems is durability. The ePRO addresses this by maintaining: You gain electronic control without sacrificing mechanical integrity. 5. Future-proofing your security investment Electronic and mechatronic access control is no longer niche — it is rapidly becoming standard in: Investing now reduces the risk of premature system obsolescence. A mechatronic platform provides a transitional pathway from purely mechanical to fully integrated electronic systems when required. Mechanical vs Mechatronic: The Real Difference Mechanical Only Mechatronic No audit trail Full event logging Physical rekeying required Credentials programmable Fixed access structure Flexible, scalable access hierarchy Lower upfront cost Lower lifetime management cost While initial investment may be higher, the total cost of ownership is often significantly lower with mechatronic systems. A smart upgrade, not a compromise The TOKOZ ePRO mechatronic cylinder demonstrates how modern access control does not have to mean complexity. It installs like a standard euro cylinder, works with traditional mortice locks, and operates with familiar key functionality — yet adds intelligence, flexibility, and accountability. For organisations looking to enhance security without rebuilding infrastructure, mechatronic technology offers a practical, scalable, and financially sound solution. If security is critical to your building’s integrity, compliance, and operational efficiency, sticking purely with mechanical systems may limit your control and increase long-term costs. Mechatronic solutions like TOKOZ ePRO provide: In today’s security landscape, that combination isn’t a luxury, it’s a strategic advantage.

Preparing School Locking Strategies for Martyn’s Law

Martyn’s Law, introduced to improve security in public spaces, is prompting schools and other organisations to re-evaluate their locking strategies. With safety under greater scrutiny, it’s important for facility managers and school administrators to understand the options available and ensure their buildings are prepared. Classroom vs Clutch Cylinders: What You Need to Know With the introduction of Martyn’s Law, building locking strategies—particularly in education and public spaces—are coming under greater scrutiny. One area often overlooked is the difference between Classroom and Clutch lock functions. In a barricade situation, a Clutch Cylinder allows a keyholder to override the internal thumbturn from outside, whilst still allowing the door to be locked from inside the room. This helps maintain control of the space while preventing unauthorised access. Traditionally, many educational buildings have used Classroom Function, but in certain situations a Clutch Function may provide a more appropriate solution. How Access2 Can Help At Access2, we can help convert Classroom cylinders to Clutch Function without affecting the existing master key system. This means schools can upgrade their locking strategy quickly and efficiently, ready for the next term or planned refurbishment.
