Dimple Cut vs Standard Edge Cut Locker Keys – Security, Specification & Availability

Compare dimple cut security keys and standard edge cut keys for commercial lockers. This guide explains security differences, wet specifications, master keying, and availability.

Understanding locker key types helps facility managers make better security decisions. This article compares dimple cut security keys with standard edge cut keys. We discuss security levels, wet specification suitability, master keying options, and availability.

Introduction

Commercial lockers, used in schools, gyms, workplaces and leisure centres, rely on mechanical keys for security and access. Replacing lost keys promptly preserves access and prevents disruption.

Two common key types are standard edge cut keys and dimple cut security keys. These differ significantly in design and security features.

What Are Standard Edge Cut Keys?

Standard edge cut keys are the traditional style found on basic locker locks. They have a flat blade with cuts along one edge. These cuts align with pins in the lock to allow rotation and access.

They are simple to produce and widely available for a broad range of manufacturers.

What Are Dimple Cut Security Keys?

Dimple cut security keys are milled with dimples or indentations on one or both faces of the key blade. These interface with more complex pins within the lock, creating a higher number of possible key combinations.

Dimple keys may also be cut in a way that allows insertion in either orientation, improving usability.

Key Design Differences

Standard edge cut keys use jagged edge profiles on one side. Dimple keys use circular or conical indentations at targeted positions across the blade.

This difference affects how the lock’s pin tumblers interact with the key and how resistant they are to picking or tampering.

Security Comparison

Security is a primary consideration when choosing between these key types. Overall, dimple cut security keys offer higher protection.

Because of their complex dimple layout and higher variation in pin combinations, dimple systems are harder to manipulate without the correct key.

By contrast, standard edge cut keys are simpler. They are easier to replicate and are more widely understood by generic key cutting services. This convenience comes with relatively lower resistance to picking or duplication.

Wet Specification and Corrosion Resistance

Lockers installed in changing rooms, pool areas, outdoor facilities and other wet environments require keys and locks that withstand corrosive conditions.

On Total Locker Service you will find wet-specification locks with keys designed for harsher conditions. Certain Ojmar models for wet areas include security keys with dimples cut on both sides and edges.

Standard edge cut keys for wet areas are typically produced with corrosion-resistant plating but may not incorporate the same level of internal lock resistance as dimple systems designed for high-use wet environments.

Master Keying and Key Control

Businesses with many lockers often require master key systems. These allow one master key to open multiple individual locks while restricting access with individual keys.

Dimple cut keys lend themselves more naturally to restricted and master key systems due to their complexity. This means duplicates and additional keys are controlled through code systems and authorised operators only.

Standard edge cut keys can be master keyed too, but they are more commonly duplicated at high-street key cutting shops, making controlled distribution more challenging unless managed through a formal key control policy.

Availability and Cutting Services

Standard edge cut keys are widely available. Most locksmiths and key-cutting services in the UK can cut these quickly.

Dimple cut security keys may require specialised machinery for accurate cutting. Not all general key cutters have the equipment, so you might need to use approved services or original manufacturer codes.

On Total Locker Service’s site you can order replacement keys cut to the original manufacturer code, including dimple and standard edge cut variants, with next-day UK delivery.

Cost Considerations

Cost Considerations

Typically, standard edge cut keys are less costly than dimple security keys because they are simpler in design and easier to replicate.

Dimple cut security keys may be marginally more expensive due to their complexity and restricted cutting requirements. However, this cost difference can be justified by the improved security and controlled duplication features they offer.

Recommendations by Locker Use Case

Dry, low-risk environments – such as staff room lockers or low-value storage – often function well with standard edge cut keys due to their ease of replacement and general availability.

High-security applications – like public leisure centres, wet changing areas, and sites with valuables – benefit from dimple cut keys. Their restricted duplication and complexity add layers of protection.

For facilities with many lockers, master key systems based on dimple technology can streamline access while maintaining compartmentalised individual security.

How to Identify Your Locker Key Type

Look at the key blade: Dimple keys have round indentations on one or both faces. Standard keys have cuts along one edge.

Check the lock code: Many locker manufacturers stamp a code on the lock barrel. Enter this when ordering a replacement to ensure the correct key type.

Conclusion

Both key types serve a purpose. Standard edge cut keys are practical and widely available. Dimple cut security keys offer enhanced protection and controlled duplication, especially for higher-security or wet environment applications.

Consider the security needs of your facility, the environment, and whether a master key system is needed when choosing between them. Using the correct key type ensures lockers remain secure and access is reliable.
