When it comes to protecting a business premises, the locks you select matter far more than most people realise. Commercial buildings face challenges that residential properties simply do not: hundreds of people passing through daily, staff turnover requiring frequent code changes, and the constant threat of forced entry attempts. Standard household hardware wears out quickly under these conditions.
At Lockey Digital UK LTD, based in Royston, Hertfordshire, we supply digital and mechanical locking systems designed for commercial use. Below, we have listed five of our most popular products for offices, retail units, warehouses, and other business premises, followed by guidance on selecting the right type for your situation.
Top 5 Lockey Products for Commercial Building Security
1. Lockey 2210 Mortise Deadbolt Digital Lock
This remains one of our bestsellers for office buildings and retail entrances. The mortice deadbolt is housed in a pocket cut into the door edge, making it extremely difficult to tamper with from the outside. Because it operates via a digital keypad, you avoid the hassle of physical keys entirely. Staff leaving the company? Simply change the code in seconds rather than rekeying cylinders or chasing down old keys.
The 2210 works well on both steel and timber doors, though you will want to confirm backset measurements before ordering.
2. Lockey 7055 Super 8 Mortise Latch
Built for heavy-traffic environments, the Super 8 range handles thousands of cycles without issue. The 7055 features a mortise latch mechanism with mechanical keypad operation, so there are no batteries to replace or wiring to install. It suits narrow stile aluminium doors commonly found in shopfronts and modern office buildings.
The biggest advantage here is reliability. Mechanical locking systems continue to function during power outages or electrical faults.
3. Lockey 2430 Mortise Latch
A versatile option for both internal and external doors. The 2430 self-latches every time the door closes, preventing the common problem of staff forgetting to lock up properly. It accommodates various backset measurements and integrates easily with existing door frames.
We often recommend this model for side entrances, back doors, and internal areas requiring restricted access.
4. Lockey 2200 Surface Rim Lock
Sometimes you need a lock that mounts to the surface rather than fitting inside the door. The 2200 rim lock attaches directly to the interior face, making installation straightforward on doors where cutting a mortise pocket is not practical. It works particularly well on fire-rated doors, where maintaining the door’s integrity is critical.
The combination mechanism provides reliable security without relying on keys or electronic systems.
5. Lockey 2500 Hook Bolt for Sliding Doors
Standard bolt mechanisms struggle with sliding panels because the door moves laterally rather than swinging. The 2500 addresses this with a hook bolt design that curves into the strike plate, preventing the door from being forced off its track. Warehouses, loading bays, and retail premises with sliding entrances benefit most from this model.
6. Lockey 2835 Mortise Latch With Hold Back-Free Passage
For commercial premises requiring operational flexibility during peak periods, the Lockey 2835 delivers hold-back functionality that allows temporary free passage during busy service hours. Retail establishments, office receptions, and hospitality venues appreciate the ability to temporarily disable locking during high-traffic periods, then restore combination security at closing without tools or complex procedures.
The free passage feature particularly suits mixed-use buildings where access patterns fluctuate throughout operating hours. Facilities managers can enable open-access mode during deliveries or customer surge periods, then return spaces to secure operation through simple mechanical adjustment that requires no electrical modifications or additional hardware infrastructure.
What Makes Commercial Door Locks Different?
This question comes up frequently, and it deserves a straightforward answer. Commercial locks differ from residential hardware in several important ways.
Durability and Materials
Business premises see far more traffic than homes. A residential front door may open and close approximately 20 times per day. An office entrance could see that number every hour during peak periods. Commercial locks use heavier steel components, brass internals, and reinforced mechanisms designed to withstand this constant use.
Testing Standards
The ANSI/BHMA grading system rates locks from Grade 1 (highest) to Grade 3 (basic residential). Grade 1 products must withstand 800,000 opening cycles, resist forced-entry attempts, and support significant weight loads without failure. Most serious commercial applications require Grade 1 or high-quality Grade 2 hardware.
Access Control Features
Unlike home locks, commercial systems often need to accommodate multiple users with different access levels. Master key systems, programmable codes, and integration with building security sensors are all prominent in commercial applications. Some electronic locks even maintain audit trails showing who entered and when.
Types of Locks Suited to Commercial Buildings
Selecting the right mechanism depends on your specific situation. Here is a breakdown of the most common options.
Mortice Locks
These fit into a pocket cut at the door edge and include configurations such as deadbolts, latches, and combination mechanisms. Mortice locks offer excellent security because the mechanism sits protected inside the door rather than exposed on the surface. They work well on timber, steel, and aluminium doors, though installation requires professional cutting.
Cylindrical Lever Locks
The most commonly used type in commercial buildings, cylindrical lever locks are installed through two bored holes in the door. They are well-suited to high-traffic areas where ease of use is critical, such as restrooms, conference rooms, and internal corridors. A locksmith can rekey or replace cylinders relatively quickly when security concerns arise. For premises requiring reinforced hardware beyond standard lever configurations, our dedicated guide to security locks for commercial doors covers the specific Grade 1 and Grade 2 options suited to high-risk applications.
Electronic Locks and Keypads
Electric lock systems and lock keypad configurations eliminate the need for physical keys. Staff use codes, fobs, or access cards instead. When someone leaves the organisation, revoking their access takes moments rather than requiring expensive rekeying. Many electronic locks integrate with broader entry systems, CCTV, and alarm systems for centralised security management.
Deadbolts
Adding a deadbolt alongside a primary lock significantly improves protection against forced entry. The bolt extends deep into the frame, resisting kicks and shoulder charges. Deadbolts are particularly effective on exterior doors and on storage areas containing valuable items.
Panic Hardware and Night Latches
Fire safety regulations often require panic bars on emergency exits. The Lockey 2230NL Front works with existing panic hardware and night latches, adding digital access control without replacing the entire system. This proves especially useful in buildings where fire compliance has already been established.
How to Secure a Commercial Door Properly
Protection involves more than just fitting a good lock. Consider these additional factors.
Door Closers
A door left propped open defeats even the best lock. Automatic door closers ensure entrances shut properly after each use. They also reduce wear on hinges and frames by controlling the closing speed.
Strike Plates and Reinforcement
The strike plate receives the bolt or latch when the door closes. Weak strike plates can be forced out of the frame with minimal effort. Commercial installations should use reinforced plates secured with long screws that reach into the wall studs, not just the door frame.
Gates and Perimeter Security
For premises with external yards or loading areas, securing gates is as important as securing building entrances. A gate lock prevents unauthorised vehicle access and protects outdoor equipment. Padlocks are suitable for some applications, but digital combination locks provide greater control over who has access.
Multiple Entry Points
Most commercial buildings have several doors: a main entrance, a back door, fire exits, and internal restricted areas. Each requires appropriate hardware based on traffic levels, security needs, and regulatory requirements. Creating a consistent access control system across all entry points simplifies management considerably.

Frequently Asked Questions
What type of locking device is most appropriate for an office building?
Most office buildings benefit from a combination of lock types. Main entrances typically use mortice deadbolts or electronic keypads for controlled access. Internal doors, such as those to conference rooms and storage areas, are suitable for cylindrical lever locks or digital combination mechanisms. Reception areas may require hold-back latches during periods of high foot traffic. The specific choice depends on traffic levels, security requirements, and whether integration with broader access control systems is critical to your operations.
Are commercial locks really different from residential ones?
Yes, and the differences are significant. Commercial-grade hardware is typically made of heavier materials, such as solid steel or brass, rather than the lighter alloys used in household locks. Testing standards also differ: Grade 1 commercial locks must withstand 800,000 cycles, compared with roughly 200,000 for residential products. Beyond durability, commercial systems often include features such as master keying, programmable codes, and audit trail capabilities that residential locks do not offer.
How do I know which grade of lock my business needs?
Consider your daily traffic levels and security requirements. Grade 1 locks suit high-traffic main entrances, external doors, and areas containing valuable assets or sensitive information. They resist forced entry better and last longer under heavy use. Grade 2 works adequately for internal doors, storage closets, and lower-traffic areas. If your premises receive more than 100 visitors daily or store high-value items, investing in Grade 1 hardware is typically worthwhile over time.
