What Is a Dimple Key? A Simple Guide to Dimple Keys

If you have ever looked at a key and noticed a row of small drilled indentations instead of the usual edge cuts, there is a good chance you were holding a dimple key. Dimple keys are a common type of security key used in many modern locks, and they appear across doors, padlocks, safes, lift systems, and other specialist applications. On We Love Keys, the Dimple keys category includes more than 100 products across brands such as CISA, ABUS, TESA, Mul-T-Lock, KESO, Phoenix, ISEO, Mottura, and more, which shows just how broad this key type really is.

What makes a dimple key different?

The easiest way to recognise a dimple key is by the small holes, or dimples, cut into the flat sides of the key blade. Unlike many standard house keys that are cut along the edge, dimple keys rely on drilled recesses arranged in a specific pattern. On the CISA Dimple Key page, We Love Keys describes these keys as having multiple holes drilled into them and notes that they are common in doors and padlocks across Europe, especially in the UK and France.

That is why dimple keys often look a little more technical or specialised than an ordinary key. Some are compact and simple, while others are part of higher-security systems and brand-specific cylinders. For customers, the important point is not the exact engineering detail but the fact that a dimple key usually needs to be matched carefully by code, brand, or clear identification, rather than treated like a generic key copy.

Where are dimple keys used?

One reason this topic is worth covering is that dimple keys are used in far more places than people expect. On We Love Keys, dimple-key products appear not only under door-related brands such as CISA and TESA, but also under bike-related ABUS products, safe-related products like Phoenix Safe Dimple Key, and specialist lift or switch key listings that also sit inside the Dimple keys category.

That means a customer searching “what is a dimple key” may actually be trying to replace a front door key, a bike-lock key, a safe key, or another specialist key without knowing the proper name for it. From an SEO and conversion point of view, that makes this blog especially useful because it can educate users while naturally leading them into the correct category or product page.

How can you identify a dimple key?

There are three main ways to identify a dimple key.

First, look at the blade. If the key has drilled holes or indentations rather than only traditional edge cuts, it is likely a dimple key. Second, look for a brand name such as CISA, ABUS, TESA, Mul-T-Lock, KABA, Mottura, or Phoenix. The live Dimple keys category shows a wide spread of brands, so branding can narrow the search quickly. Third, check whether there is a code stamped on the key or shown on a code card. Many of these products are ordered by code rather than only by eye.

The product pages on We Love Keys make this very clear. The CISA page says the code is usually stamped on the head of the key or shown on a code card. The ABUS EC Extra Classe and D6 page says the code is often on the key or code card and can begin with prefixes such as N, D, DN, DF, W, SM, ZY, E, or EC. The TESA T60 page says its codes usually start with 69. Those examples show why code-based ordering is such an important part of dimple-key replacement.

Are all dimple keys high-security keys?

Not all dimple keys are the same, but many are associated with higher-security or more specialised locking systems. The ABUS EC Extra Classe and D6 page, for example, says these keys are used in high-end ABUS products including bike locks, padlocks, and door cylinders. That does not mean every dimple key is a premium security key, but it does explain why many people encounter them in products where accurate replacement matters.

In practical terms, this is why customers should avoid guessing. A dimple key may look similar to another key at a glance, but the correct replacement depends on the exact brand, profile, and code pattern.

What should you do if you need a replacement?

Start with the simplest route: check the key for a visible code and brand name. If you have both, you may be able to go straight to the correct product page. If you do not, use the Dimple keys category to compare likely matches and narrow things down by brand. If you are still unsure, We Love Keys already has a Find My Key process that lets customers send details or photos for help identifying the correct key. That matters because the Dimple category includes many different products that look similar at first glance but belong to very different systems.

Final thoughts

A dimple key is not just one product. It is a broad key type used across many brands and applications, from doors and padlocks to bike locks, safes, and specialist access systems. The easiest way to identify one is by the drilled dimples on the blade, then by checking the brand and any visible code. Because We Love Keys already has a deep Dimple keys category and several strong product examples like CISA, ABUS EC Extra Classe, and TESA T60, this topic works well as both an educational guide and a path into product discovery.
