This guide explores the security and lock products available, explains security ratings and standards, and helps you choose appropriate solutions for your specific needs. With ABUS alone providing over 1,200 products in our security range, you'll find professional-grade protection for virtually any application.

Understanding Security Ratings and Standards

Not all locks provide equal protection. Security ratings help you select appropriate products for your risk level and insurance requirements. Sold Secure ratings—Bronze, Silver, Gold, Diamond—indicate resistance to different attack methods and durations. Higher ratings meet more stringent testing criteria and resist determined attack for longer periods.

Insurance companies often specify minimum security standards for coverage, particularly for commercial premises, high-value goods, or certain business types. Check your policy requirements before purchasing locks—installing inadequate security may void your insurance regardless of how secure it appears.

CEN ratings (European standards) classify locks from 1 to 6, with higher numbers indicating greater security. These ratings consider factors including drill resistance, pick resistance, physical strength, and corrosion resistance. Understanding these ratings ensures you select locks that match your actual security needs rather than relying on appearance alone.

Padlocks for Every Application

We stock over 1,300 padlocks covering applications from luggage security to industrial gate protection. Padlock selection depends on several factors: shackle clearance, weather resistance, key systems, and security rating.

Keyed Padlocks

Standard keyed padlocks remain the most common choice, offering good security with straightforward key management. Brass bodied padlocks provide basic protection with reasonable corrosion resistance, suitable for indoor use or protected outdoor locations. Laminated steel padlocks add strength for demanding applications, while weatherproof designs include sealed mechanisms that exclude moisture and dirt.

Marine-grade padlocks use stainless steel construction and sealed brass mechanisms to withstand coastal environments where salt spray rapidly corrodes standard locks. For contractors working in multiple locations, padlocks with replaceable cylinders allow rekeying without replacing the entire lock body.

Combination Padlocks

Combination locks eliminate key management—no lost keys, no spare key distribution, no rekeying costs. They suit applications where multiple users need access or where key security presents challenges. Modern combination mechanisms provide security comparable to keyed locks, though they require memorizing or recording code numbers.

Resettable combination padlocks allow code changes when staff leave or security becomes compromised. Some models include shackle-less designs that resist bolt cutter attacks by eliminating the exposed shackle entirely—the lock body threads through a hasp or chain with no vulnerable point to cut.

Keyed Alike and Master Keyed Systems

For multiple locks across a site or property, keyed alike systems use identical key cuts so one key opens all locks. This simplifies key management but means losing one key compromises all locks. Master keyed systems provide individual keys for each lock plus a master key that opens all locks, useful for managers needing access to all areas while restricting individual staff to their specific zones.

ABUS and Yale provide comprehensive keyed alike and master keyed options across their padlock and cylinder lock ranges. Planning key systems in advance prevents security issues and reduces costs compared to ad-hoc lock purchasing.

Door Locks and Security Hardware

Door security starts with proper lock selection and extends to hinges, strike plates, and door construction. We stock over 850 door locks and security products including mortice locks, cylinder locks, bolts, and specialized security hardware.

Mortice Locks

Mortice locks fit within the door thickness, providing robust security for external doors. Five-lever mortice locks offer reasonable security for basic applications, while British Standard (BS3621) approved locks meet insurance requirements for domestic properties. Deadlocks provide key-only operation on both sides—no internal handle release—essential for some insurance policies and security-critical applications.

Sashlocks combine deadlocking with handle operation for day-to-day convenience, automatically locking when the door closes while providing key override. Euro profile cylinder locks have become standard in uPVC doors and many modern timber doors, offering quick cylinder changes when rekeying becomes necessary.

Cylinder Locks and Euro Cylinders

Euro cylinders vary dramatically in security levels despite looking similar externally. Basic cylinders offer minimal pick and drill resistance, adequate for internal doors but vulnerable on external doors. Anti-snap cylinders include sacrificial sections that break under attack but leave the locking mechanism intact. Anti-drill pins resist drilling attacks. Anti-pick pins complicate lock picking.

British Standard cylinders (TS007) meet rigorous security testing including snap attack, drill attack, and pick resistance. For high-security applications, choose cylinders with multiple attack resistance features—anti-snap, anti-drill, anti-pick, and anti-bump protection all contribute to overall security.

Bolts and Additional Security

Supplementary bolts add security to standard locks, particularly useful for doors opening outward where hinge access becomes a vulnerability. Tower bolts, mortice rack bolts, and security chains all provide additional protection points. Surface-mounted bolts offer straightforward installation, while morticed designs provide hidden protection that cannot be compromised by removing external fixings.

Hinge bolts prevent door removal even if hinge pins are accessed, essential for outward-opening external doors. Security chains and door limiters allow partial door opening while preventing forced entry, useful for checking caller identity before fully opening doors.

Hasps, Staples and Gate Security

Securing gates, sheds, and outbuildings requires hasps and staples that match your padlock security level. A high-security padlock paired with flimsy hasp defeats the purpose—attackers will simply remove the hasp rather than attacking the lock. Heavy-duty hasps use through-bolting and reinforced construction that resists prying and fixing removal.

Close-shackle padlocks work with specialized hasps to minimize exposed shackle, making bolt cutter attacks extremely difficult. For containers and commercial gates, heavy-duty staples through-bolt to prevent lever attacks. Coach bolt fixings resist removal from the secured side, particularly when ground smooth to prevent spanner grip.

Security Solutions for Construction Sites

Construction sites present unique security challenges—temporary structures, multiple access points, transient workers, and high-value equipment all attract theft. Container locks with protected shackles and drill-resistant bodies secure storage containers. Gate chains and high-security padlocks control vehicle access. Site safes provide certified storage for tools and small valuable items.

For site compound fencing, secure the chain link or panel edges properly—fencing only works if it cannot be easily lifted or cut. Round bar locks prevent unauthorized trailer coupling. Fuel tank locks prevent fuel theft from plant machinery and generators. Implementing multiple security layers increases difficulty for thieves and reduces losses.

Insurance and Security Recommendations

Insurance companies provide security recommendations or requirements based on your risk profile. These might specify lock types (five-lever mortice deadlocks, British Standard approved), security ratings (Sold Secure Gold), and installation standards (lockable windows, external door protection). Meeting these requirements ensures claims won't be rejected due to inadequate security.

Document your security installations with photos, receipts, and certification where provided. This evidence supports insurance claims and demonstrates due diligence. Some insurers offer premium reductions for enhanced security—upgrading locks might save more than the installation cost over time.

Access Control and Modern Security

Beyond traditional locks, modern security includes electronic access control, smart locks, and integrated alarm systems. Electronic keypads eliminate physical keys while allowing immediate access code changes. Smart locks provide remote access control, activity logging, and integration with alarm systems.

For commercial applications, proximity card readers, biometric scanners, and time-based access restrictions provide precise control over who accesses which areas and when. While more expensive initially, these systems reduce lock replacement costs, eliminate key cutting, and provide security audit trails.

Key Control and Management

Physical key control prevents most security breaches. Restrict key duplication through registered key systems where key blanks require authorization before cutting. Number keys and maintain key assignment records showing who holds which keys. For staff changes, either collect keys or rekey affected locks—assuming returned keys represent all copies risks security.

Master key systems require careful planning to prevent security compromise. Each additional key in a system provides another potential point of failure. Document key hierarchies and regularly audit key holdings to ensure current records match physical reality.

Lock Installation and Maintenance

Proper installation determines whether security hardware performs as designed. Mortice locks need adequate door thickness—installing five-lever locks in thin doors weakens the door more than the lock strengthens it. Strike plates must mount into solid timber or masonry, not just door frames—a robust lock defeats purpose if the frame fails.

Maintain locks through periodic lubrication with proper lock lubricants, not general-purpose oil that attracts dirt. Clean key surfaces prevent pin jamming. Check cylinder alignment in euro locks—misalignment from door settlement creates insertion and turning difficulties. Replace worn locks before failure—a lock that sticks occasionally will eventually fail completely, potentially at the worst possible moment.
